Field Trip and Seminar's Travel Report

Fieldtrip Overview:

Let’s start by defining first what fieldtrip is, fieldtrip is a journey or rather a school trip wherein students are having a trip outside the university or school’s campus. It is basically practiced to showcase some information coming outside the wall or promissory of the school for students. The main purpose of conduction fieldtrips and seminars is basically to let students learn more, to critically observe things, to experience a different learning environment and to have an unusual kind of interaction. This method or approach of teaching quality learning to students had been very helpful for them to grow.

Frankly it was my first time having a fieldtrip outside the city - it was like more of interesting rather than exciting. There are also some first timers in the group, and all are excited of what is the outcome of the fieldtrip. Well as being defined, there are really lots of enjoyable things to learn and discover in joining fieldtrips. Amazingly things went right; accommodations are good, services are fine and we’ve caught up each of our company seminars, meetings or appointments. Had heard a rumor about the last year’s fieldtrip and seminar, and it wasn’t that good though, however each side had some advantage and disadvantage. The field trip held last year, wherein some of my classmates joined had started and ended a bit chaotic because of some delays, but more exciting and jolly since there are couple of friends to be with. It might have been because of their numerous populations that companies could not accommodate each of them well. And also because of the numerous fieldtrip participants, a higher percentage of delay caused by a fellow participant is of an elevated risk. At our part, since we’re outnumbered by them because unfortunately only few students could attend and participate at the fieldtrip, we are lucky because companies could accommodate us well and could cater each of our questions without a hurry of answering it. And since the crowd is not that big, lecturers could impart their knowledge to us the best and comfortable way they can with additional joke cracking to keep the interaction alive.

The trip had gone somehow smooth. Itineraries are already prepared to serve as the basis on which and where to go first and next. Time had already been calculated and managed to ensure a good flow of things. It’s like most of the things had been well prepared and anticipated. Starting from day 1 down to the last day of the trip is already scheduled, and each company had their own slot. At day 1, a direct visit to the prestige company of PLDT and then a quick trip for a visit at the SPI Servisoft. The whole day 2 was spent for the most awaited y4it held at the University of the Philippines or UP. Day 3 with the Flour Company and right after was the visit to DOST where a museum or collections of important part of the Filipino – Science History could be found. And day 4 at the Social Security System or SSS and then a visit to Exist Global Company. It was the last day for company visiting since the remaining day 5 was already allotted to have the shopping spree, leisure and having fun (maybe the day we’ve all been waiting for, to ease the stress of pulling ourselves in bed to wake up early each day). These known companies had been a part of our Fieldtrip wherein each of them had showcased variety of helpful information for us participants.

Each company shared different topics, had introduced us to some technologies, guiding us a tour to their company and showing each of the fundamental departments that serves as the main foundation of their company, like their network management team, editorial, database managers, programmers, content writers, designers and even the room that contains their servers which contains various data and plays a vital role for the company. Multiple topics and information and knowledge are being fed to us each day and no one could avoid rating the topics or rather the presenter of the topic for some are interesting, caught our attention while some are just boring like having their reviews or reports in a power point presentation, reading them like as if they were really not into it in their career as an IT professional. Even though, still they had managed to impart us some knowledge which could be considered as a present from them to us.

To sum it up, although some or even few of the companies mentioned had a flaw with their sharing and presentations, each tour and visit is considerably grateful and much or highly appreciated. For the knowledge and time they had spent and shared with us, and for cheering us to continue with what we had started for, I thank them and owe them a lot. And for the chance to participate in the fieldtrip, it is a great pleasure to be a part of the event and to witness and be showered with the knowledge conveyed by everyone.

Day 1

A visit to PLDT

This is the very first day of our fieldtrip. After packing things up and having hours of air flight, we were urgently fetched by a bus to deliver us directly to our first company visit at the company of PLDT or the Philippine Long Distance Telephone Company. Despite of suffering from jet logs, we were delivered at the company to start and follow the scheduled flow of our trip itinerary. Now to start with, PLDT is one of those large Tele communications Company who gives service and supports communications here in the Philippines. In fact, Philippine Long Distance Telephone Company or the PLDT is the largest Tele communications Company in the Philippines. They offer variety of services from fixed lines, wireless, up to technology and information technology. Services mentioned above are the main services offered by the company to its valuable consumers.

As we were toured by a staff to the hall of PLDT and introduced unto us the company’s history, from the oldest form of communication and telephone to the newest technology including the wireless and internet services that we or almost all people are enjoying now. Base on the company’s history, telephone and communication users in the past are just only a few ranging from thousands but as services went good and affordable, lots and lots of users embraced these form of communication wherein it had covered the most islands of the Philippines. As a company, PLDT had also undergone some reconstructing which made the company robust and running ‘til the present period.

After the company tour, we had been given the chance to have a meeting and conversation with one of their veteran networking experts in the company. So basically, this is the part where I liked the most in visiting and spending my time at the Philippine Long Distance Telephone Company PLDT. The veteran networking expert lectured and introduced to us some of their ways, the company’s basic foundation and also he explained why internet connections and even text messages sometimes fail while the weather is suffering from a bad rainy season. So, from what that veteran networking expert of PLDT explained, I had learned that the PLDT’s way to earn an income is to sell cables and wires. Selling cables and wires to some consumers that would connect a communication tool or telephone from one side to the other side, basically some entrepreneurs who want to manage their business with multiple branches in an easier and efficient way. He introduced us some ways and manipulation to ensure a good flow of connection, wherein he mentioned something like a dual stream where if the main stream suffers from congestions or any traffic, the connection will be redirected to the backup stream to have a continues flow. It is just some of their ways to implement flow and traffic control. Also, he had mentioned about a certain part inside a wire or cable in which connections flow that plays an important role in connection with the company services, because without which, there will be no medium for the connection to run through. The most interesting part is the explanation for the late messages and weak connection when a bad weather is ongoing. When there is rain, literally connection disperses. It is because of the raindrops that affect or destroys the connection which instead of going directly it would take another path which makes its travel time longer.

For the very first company visit, it goes well and fine. The lectures provided were great and so far there’s nothing I didn’t like about the company. Although we suffered from shortage of time, facts, ideas and knowledge fed to us were stored in our minds through interactive conversations.

A visit to the SPI Servisoft

The second company we visited for the first day of fieldtrip in manila is the SPI Servisoft Company. SPI is a communication and Information Technology company somehow or somewhat related to PLDT. SPI supports and offers services like cost-effective business solutions, software creation and etc.. The company staff led us to a tour around the company and took us to the different areas inside the company.

As far as I could remember, one of the lecturers talked about business solutions, the other went to the topic of using a programming language, and the other one talked about his field the technical support service I think. So let’s take it one at a time, for the business solutions they had variety of effective ways to help a business improve its work efficiency and rating in the economical industry. One of the SPI Company’s programmer talked about using I think it was .net, or something like c#. He shared his experiences, like his past of being fascinated and using PHP but ended up using other programming language. So it’s like explaining to us that we really don’t know what’s were going to deal with when we will be indulge in a company. And the other one explain his field which is the technical support, which according to him has tiers and each tier level has their own specialties. Problems occurrence and its difficulty will decide which tier it will be taken to.

Frankly, I didn’t learn a lot from them, but let me give credit to the company tour. Don’t know if I couldn’t just fix my mind for listening mode or I’m not just simply interested with the topics they had been talking to.

Day 2

A visit to UP for Y4it

For day two (2), we had our next adventure and spent the whole day at the prestigious University of the Philippines or commonly known as the UP. And by the way, University of the Philippines or UP is a high class university in the country which produces high quality and competitive graduates in different aspects and fields. UP is where Y4it was held, and it was a good idea to celebrate or hold our major fieldtrip simultaneously in sequence with the Y4it. Computer science and Information Technology representatives coming different schools and universities from the different regions inside the country had been gathered at UP just to stay, witness and be a part of the celebration of Y4it. At the event, there were multiple and numerous topics being shared which were categorized and were split to different houses. Some topics could be heard from the Film Theater, some are from the Bahay ng Alumni and still there are 3 more other sites. At Y4it, there are IT and technological experts who joined and shared their parts to help rise the quality of students in the Philippines. Couldn’t talk about the entire topics covered in the event for we have to choose unto where and which station to stay, which basically depends on our point of interests.

So while I was reading the sheet of paper where the whole Y4it program was listed, a topic about gaming caught my attention and it was held I think at the University’s Film Theater. So after the bus arrived and dropped us on a dropping area, I together with my classmates and some other participants urgently started walking the path to the university’s Film Theater to have our lines and reserved a seat for the coming lecture. So there it was, several minutes later the lecture had started. The topic is more about the new technologies and gaming. One of the speakers I think was actually still a graduating student (didn’t know where school did he came from) and he talked about the windows phone which is absolutely powerful but too expensive. He boasted some of the phone features and qualities which made it cool and awesome. A speaker also shared to us his experience in the field. According to him, he had been working for some huge companies outside the country and had been a part of some successful projects. He taught us some important things to take note when facing the industry through his sharing.

So for the second day of our fieldtrip, what didn’t I like? Actually, as mentioned there are multiple sites inside the university’s campus offering different topics and each site is composed of different students sharing common interests. Now, let me just focus on the Film Theater. Actually I was a bit unhappy of what I had heard when the speakers are talking, as I were reading the catalogue or the paper containing the orders and schedules of the event, I read something about on teaching on how to build a game – just something like that which caught my attention. I thought being inside the Film Theater and taking time listening to them could give me literally some ideas on how to build a game, or even just simply the basics of doing and building it. All I heard was just practical life sharing and endorsing new innovations of technologies, which is still great but didn’t match what I really expected to have or hear to. But honestly I wasn’t given the chance to go inside the Film Theater after leaving there for a lunch break for as the gate keeper told us that there’s no vacant space left inside the theater so we had just wandered around collecting freebies and stuffs from different companies who also participated the event.

Day 3

A visit to Fluor Company

For the day three, our itinerary is to have a trip and visit the Fluor Company. It was a huge company who deals with constructions, engineering, procurement, and networking and information technology. And by the way, Fluor is a one big company with branches scattered throughout each side of the world. In fact they boast to have their next business branch somewhere in Cebu which is known as a hub for professionals and IT experts. And just to add up, they are the only company who’d fed us with some heavy snacks. Lol!

As we entered the company, the company HR greeted us as a form of a formal welcome. She guided us to a conference room where a long but informational presentation is already awaiting. The HR started the talk and asked us about how do we fix our resumes, and so we did, we told her of our ways and she also shared her way. As an HR manager, she is as expected expert and had more experience in terms of dealing with these kinds of things. And according to here, the most effective approach to have a higher chance of being hired is through the presentation of resumes, HRs or businessmen by any chance wouldn’t take a look about the personal background of the applicant but it’s more on the applicant’s working experience, history, highlights and educational background. So base on these ideas, she mentioned that in every resumes, we must consider putting those things together with our personal vital information and career objective at the very first page of the resume to catch the attention of the possible reader. The next speaker lectured about the importance of having a strong team. The speaker tackled about the 6 things a successful team has in common, like the: team’s purpose, process, communication, involvement, commitment, and the very important part the trust. The speaker explained to us that no matter how weak a member of a team was, the team will always be there for that person, to help that person grow, mature and learn what he or she needs to learn in order for him or her to be successful and for the team to accomplish each tasks granted to them. Helping each other and growing as a team is the main key for the team’s success. The next part is the lecture about networking which tackles about defense systems, routing and communicating.

 The best part of having visiting the Fluor Company is the wonderful tour, where we were guided by some of their experts and explaining us deeply each and every purpose and some general things to be shared in a specific are, like the time we were brought to a room full of servers, hubs and other things wherein an expert shared unto us some important matters like the role and importance of maintaining the humidity, moisture and proper temperature inside that room.

So what I didn’t like at Fluor? Nothing, because the company is just really great, their accommodating, had accompanied us and had really spent good time teaching us some pretty good lessons.

A visit to DOST

DOST or the Department of Science and Technology here in Philippines as we already know is a government organization established to conduct studies, researches and innovations in science life and as well as in technology. Different innovations through the help of science had been implemented by the Department of Science and Technology in the country to help the economy and industries rise.

Actually, our visit at DOST had only lasted for only few hours since they could only offer us one speaker for that day. The speaker started his talk about the current status of IPv4 or the IP version 4. IP is a unique address of a computer set to serve as the computer’s ID while surfing over the internet. Through IP addresses, data and other vital information stored within the computer could be revealed to hackers when they have the address. This is why there are some business related spams being generated through mails using our own emails. So going back, he mentioned about the shortage or the IPv4 running low and the near adoption of the IPv6. He told us some facts and details regarding some businesses already reserving their own domains for future purposes.

Besides from being alarmed of what the speaker had mentioned and for a bit sharing, I haven’t learned that much but instead drawn out my attention to their museum where some culture and scientific inventions made by Filipinos where preserved.

Day 4

A Visit to SSS

SSS or the Philippine Social Security System is an organization in the country that protects the people’s well-being from the social and economic distresses. Dealing with SSS as far as I am concerned is like a future investment in which any people who had been their member for specific years could avail their services.

SSS could be availed in different approaches, if the applicant is currently working on a company, the applicant and employer will share and equal contribution as a monthly payment for the applicant’s membership. And the other one is through voluntary, in which it is more expensive because there’s no employer who could share half of the payment that should be done. But anyway, being a member of SSS has numerous advantages like being insured with assistance in misfortunate times and taking a loan to start with something up.

Besides the importance of having the SSS in the near future, that’s all I had learned from them. So basically visiting the company is not that time or cost-benefit for me.

A visit to Exist Global

Visiting Exist Global is the last company visit we’ll be doing in our fieldtrip. So anyway, who’s Exist Global? What kind of company are they? Well, exist global was founded in the year 2001 and is a product development firm who develops interactive web applications, mobile applications, software and business solutions, enterprise software and etc.. Exist Global is a company of the type software provider who promotes the aid of open source tools as a way of building or creating a system. Because they are more up to using open source tool, programmers within the company are centered on using or more on using Java and Ruby on Rails.

One of the things I learned in exist global is the topic of “Companies Hire Depending on the Business Plan”. 1.) Companies hire new applicant because they want to introduce new products and services and they want to find a new man who’s suitable for the job. 2.) Companies hire new applicants because they want to grow their current team, to make it stronger through adding manpower. 3.) Companies hire new applicants simply because they want to cut some costs, because veterans are paid at a higher percentage so they’d rather hire and train a new one which is basically of cheaper cause for the mean time. 4.) To increase leadership, they might try to find an individual who’s capable of managing a leading a team to its success, and the last thing, 5.) Social Media.

Day 5

The last day of stay was allotted for the extended shopping spree, wandering around and having fun. We had jumped over the Mall and start to budget our remaining money and that’s where we learned the art of asking for discounts.

Appendix
The entire trip was fun and enjoyable, in the end several information, ideas and knowledge were shared and given to us by the companies we visited. The idea of taking the fieldtrip simultaneously with the celebration of Y4it is indeed great. I have only some concerns which I think might help the next batches who will be taking the fieldtrip, one is about picking the right company who could cater and share valuable information and knowledge to everybody. Because as mentioned above, it is a bit disappointing to end up not that satisfied enough of the lectures and sharing provided by a certain company. And the other one is about ensuring that the company could handle certain number of students. Because as what we had experienced, it is likely great to be in few numbers rather than in a pack of hundreds of students, else they could be broken to batches so that the crowd can be controlled hence ensuring that the students can focus and understand each lecture.
But all in all, in went somehow just fine. Thank You!





The 2nd Developers Connect


Developers Connect or preferably known as DevCon is an organization established support the growing population of young developers in the country. DevCon offers conferences wherein team buildings, interaction and knowledge are being shared to participants to help them grow and build their dream. As for now, the Institute of Computing had already embraced or joined DevCon’s community for already more than a year. Seminars and gatherings had really been a good help for students like us. Professional IT lecturers shared different interests thoughts, and ideas to share students of the possible fascinating things they might want to be indulged with and it’s a pleasure to say that those knowledge imparted had opened our young minds of the different fields in the profession were pushing through.

The Institute of Computing’s 2nd Developers Connect was attended by multiple students. During the program, some students were asked to have their thesis or research presentation. Part of the program was intended to give a chance for those students to experience an actual presentation in front of the crowd to help them build their confidence to face the world outside the university’s wall. It was an effective approach for them to improve or discover some of their hidden talents in defending what they’ve created and facing the crowd.

DevCon held Lightning Talks served by IT experts and Birds of Feathers with the topic about Operating Systems. Wordpress, Drupal, Python, ideas on how to retrieve a lost laptop and the significance of online map are just some of the coverage of the Lightning Talks. Topics being presented are all Open Source, meaning, these tools and software is free of any charges. Wordpress had been introduced during the presentation by one of the speakers. Wordpress is a powerful open source CMS tool with embedded features and templates that could help anyone create a dynamic website with less worry. Through the aid of the tool, managing work flows and procedures is now easy. Drupal on the other hand is more likely similar to Wordpress. Drupal is also a competitive open source CMS tool that could run in nay platform and supports the use of PHP and common databases like MySQL, Microsoft SQL Server and etc. Python is really not that much known to Filipino programmers as for the moment, but Python users had been growing in population as programmers multiply. Anyway, python is a programming language and is also free to use. It runs with Windows, Linux and Mac Operating Systems. The speaker of this topic leaved a funny but interesting quote, “There are only few users of Python Language for programming here in Philippines, hence making a good deal of encountering good offers as a Python user”. Another topic is an idea of how to retrieve a lost laptop, as far as I could remember it goes something like this. Each unit has its own unique IP address which is composed of binaries which represents or serves as the unit’s ID while surfing over the internet. The main idea is to track down the lost unit through tracking the unit’s current position through its IP address as it connects over the internet. Though it might just been an idea, but it could possibly be brought to reality by some programmers. The last one is the significance of online mapping. There are teams out there, plotting each street in the City, making a visual representation of them to contribute to an online map. This powerful map keeps down a track of possible routes that is mostly helpful for travelers and emergencies. Showing the shortest path and revealing possible routes to go through is the main purpose of maps basically. Through this, response time for emergency rescues perhaps is optimized.

It’s a pleasure joining the event and learning a lot from these experts coming from different fields. Hope to see them around next time to keep an update from outside community.

ES321 EXERCISE 1

Exercise 1

Observe skilled and novice operators in a familiar domain: for example, touch and 'hunt-and-peck' typists, expert and novice game players, or expert and novice users of a computer application. What differences can you discern between their behaviors?




                Technology brings about the need to learn and acquire new things. And as technology grow and develop, the more human requires to get hold of these new and innovative things. Human behavior is said to be complex but nonetheless, random. The growth of technology largely affects the human behavior; and thus human behavior also affects the growth of technology. However, the way that human deals and interacts with technology also depends on the training and the environment he receives and encounters. 

At some point, not all people accept and understand quickly the changes in technology. Being skilled and a beginner in using modern technology really matters on how it is regularly used and practice. There is definitely a difference between the two in applying technology. Let’s take for example some scenarios stated below:

·         Touch and ‘hunt-and-peck’ typist
These individuals are obviously doing the act of typing, however they differ on how fast or how they can type accurately and conditionally. Touch typists are often called professional typists. They keep their eyes on the source copy at all times uses their ten fingers and avoid looking at the keyboard when typing. They often do their typing works fast and accurate and lessens the time of work. However, hunt-and-peck typists also known as search and peck typist are the contrast of touch typists. They look at the keyboard and tap the keys with only a few fingers (sometimes only two fingers).  They are clearly much slower than expert typists. Usually, they are unable to focus on their works since they always look on the keyboard while typing. This affects the quality of their work. Though there can be accuracy in their outputs, it increases the time of work and thus sometimes slows the time of completion of an output.

·         Expert and novice game players
Differentiating Expert players against Novice players, as expected, these Expert players do have wide knowledge about a specific game. Since novice players are beginners, they are often more on explorations and generating questions. Looking back at their performance, Expert players do have several advantages especially in experience unlike the novice players. Now, taking some tactical games, Expert players can generate certain tactics towards the game and since Novice players are still learners they usually discover these tactics through and when they experienced it.

                Practice makes perfect, that what they say. In order for these novices to become experts, they should strive hard to commit the power over the technology. Experience still plays a vital role, for it encompasses learning and the creation of facts and ideas.

ES321 EXERCISE 4

Exercise 4

Can you think of any instances in which the 'noun-verb' guideline for operations, as suggested in the Apple human interface guidelines for the Desktop Interface, would be violated? Suggest other abstract guidelines or principles besides consistency which support your example. (Hint: Think about moving files around on the Desktop.)


The noun-verb guideline suggests that we can view all operations that the user will perform as being composed of an action (the verb) acting with one argument (the noun). In the case of moving a file (or copying, for that matter), the action (move or copy) requires more than one argument. The way the move operation is performed requires the user first to select the icon for the file to be moved and then to indicate the move operation implicitly by dragging the selected icon to the destination folder. The nouns in this dialogue are the file to be moved and the destination folder. The verb is the move operation. The natural way to express this is in the order noun-verb-noun. Strictly speaking, in order to stick with the noun-verb guideline, we would have to indicate both the target file and the destination folder before indicating the move operation. That would be consistent, relative to input expression, with most other commands on the desktop. However, some principles of direct manipulation and familiarity to the user are more important. Moving files by dragging them on the desktop is very similar to the way we can pick up any object in the physical world and move it to its new location. And the dragging operation is incremental and easily recoverable; moving to one place can be undone within the same operation since the dragging can continue until the file is released.

The file-moving example is a slightly contrived one, because some could argue that there is no violation of the noun-verb guideline (hence, moving is still consistent with respect to input expression) because the verb is 'move to destination folder'. Perhaps a better example is a command to search a file system for files matching some specification. Here, the action is to do the qualified search and the argument or noun is the set of folders or volumes of the system that you want searched. Typically, this kind of operation is defined by some dialog box that allows the user to indicate in any order the specifics of the operation (the search parameters) and the folders or volumes to search. Once this unordered dialog is complete, the user then indicates that it is OK for the system to perform the operation. This kind of form-filling dialog subscribes to neither the noun-verb or verb-noun guideline; the order is more flexible for the user than consistent.

ES321 EXERCISE 3

Exercise 3

What influence does the social environment in which you work have on your interaction with the computer? What effect does the organization (commercial or academic) to which you belong have on the interaction?


Talking about the social environment I am with, the presence and usage of the technology specially computers is widely in common. The influence of computer gaming is one of the major reasons of the Human-Computer interaction, and also, these interactions are present due to the profession i had chosen.
Through the extensive usage of this technology, organizations whether commercial nor academic had grown popular. Academic organizations had been requiring the knowledge about computers, which includes the usage of these devices to meet certain school requirements. These organizations had contributed a lot on the interaction, some of its effects are addiction, knowledge and the growth of technology.

ES321 EXERCISE 2

 Exercise 2

Pick a couple of computer input devices that you are aware of (joystick, light pen, touchscreen, trackball, eyegaze, dataglove, etc.) and note down how each has different attributes that support certain forms of interaction. You ought to know a little about all of these devices - if you do not, research them.


The following devices are input devices that supports Human-Computer Interaction:

In computing, a keyboard is a typewriter keyboard, which uses an arrangement of buttons or keys, to act as mechanical levers or electronic switches. With the decline of punch cards and paper tape, interaction via teletype-style keyboards became the main input device for computers. Supports interaction by having the users to input their commands by pressing its buttons or keys.

A light pen is a computer input device in the form of a light-sensitive wand used in conjunction with a computer's CRT TV set or monitor. It allows the user to point to displayed objects, or draw on the screen, in a similar way to a touch screen but with greater positional accuracy. Interactions occurs when users points the pen to the screen.

A touchscreen is an electronic visual display that can detect the presence and location of a touch within the display area. It enables one to interact directly with what is displayed. Similar to a light pen, touchscreen carries interaction by allowing the user to manipulate a device through touching it by hands or fingers.

A trackball is a pointing device consisting of a ball held by a socket containing sensors to detect a rotation of the ball about two axes.

A joystick is an input device consisting of a stick that pivots on a base and reports its angle or direction to the device it is controlling. Joysticks are often used to control video games, and usually have one or more push-buttons whose state can also be read by the computer.

As you can see, this devices are commonly used to manipulate the Computer, which results to what they called as "Interaction".

Expert Judgement Tool

ProjectManagement Assignment 5 : What is the best tool use in expert judgment?

It was been discussed before that in order to organize a project, the project team is required to split or break the main project to several phases. These phases are composed of unique processes, and it is constructed with prerequisites. Some or most of these phases will encounter a technique called the Expert Judgment. To handle some risks, generate ideas and decision makings on the project, expert judgments are being conducted to guide the project team.

Expert judgment is mostly used in developing project charter, direct and manages project execution, perform integrated change control, define scope, estimate activity resources, estimating costs, identifying stakeholders, perform qualitative risk analysis, plan risk responses, conducting procurements and etc.

Defining what expert judgment is about: Expert judgment is a common technique used in estimation methods. Most judgments are based on expertise being acquired from specific areas and knowledge, which concludes that this method merely relies on factors such as gained experience from past projects. Which reminds me of something, having students consulting to a mentor for an approval or changes is also a practice of this expert judgment! LOL! Expert judgment is often used to assess the inputs needed to develop the project charter. Through this, gaining an edge using historical data is no more an issue. Inaccurate estimation definitely leads to failure, that’s why accurate data are important to set a mark for those estimations.

Through observations, I had managed to come up with a disadvantage regarding to the matter of having this expert judgment. Yes it is true that through this, the project team could have the advantage of securing the outcome of their project, hence giving them the assurance for a better quality. But using this technique or approach, the project team would spend a large time especially when taking the path of having the interviews and consults. Thus, the project team should be well prepared for consequence of using it or simply its drawbacks.

Any individual who has the knowledge and experience relating to the project could be considered as an expert. It could be a member of the team, an individual with same project in the past, and the project manager. But to avoid having biases, it is more appropriate to have an expert who’s outside the project, an individual or a group who’s not related to the project itself. Through this, the team could have an assurance of having the judgments straight, clear and real.

Expert judgment is a technique right? Where in this expert judgment is an approach to secure the quality of the ongoing project. Tools are being introduced to support this approach or rather the technique. Some tools that could be employed in this technique are the following:

Interviews – Interviews are common to us, this is a tool we had been using specially when we are in doubt or we do not have knowledge on something, it can go to a one-to-one or a many-to-one basis (which is compose of the expert and the apprentice or the project team). Interviews are conducted by asking a series of related questions to an expert or an individual whose knowledgeable that will increase your knowledge of the project or a particular project activity.

Brainstorming – Brainstorming is basically about sharing related ideas, knowledge and solution as an approach for a specific problem. This works by getting a group to focus on a problem and then coming up with as many ideas as possible to determine an absolute solution. The goal of brainstorming is to achieve a broad list of project risks and solutions to terminate further damages to the project.

Consulting – Another tool of expert judgment, in which the project team will come for an expert to have a consultation regarding to the risk and progress of their project. An effective approach, for it could give the project team the path that they must take and a consultant that will test and neglect some options.

Historical Data – Historical data uses the knowledge gained on a similar past project activity to obtain duration estimates for each activity associated with a current project. With the proven data, the team could compare and come up with a better approach or implementation for the project.

Using these tools and techniques, the project team could expand their knowledge about the projects’ risks control and on how to deal with the several options and additions for the developments and progress of their project.

Below are some techniques that still comprise the expert judgment (innovations made to cover the weaknesses of the said technique.):

Another technique that can be applied to handle risks and conclude ideas and solution is the analogous estimating. Analogous estimating is one form of expert judgment and it also known as Top-down Estimating. This approach or technique is mostly reliable when the previous activities are similar in fact and not just in appearance, and the project team members preparing the estimates have the needed expertise. This estimation technique will be applied to determine the duration when the detailed information about the project is not available, usually during the early stages of the project.

Another technique for judgment is the Delphi approach or Wideband Delphi technique attempts to gather the opinions of a group of experts with the aim of producing an accurate unbiased estimate, as mentioned earlier that having expert judgments with the project manager or anyone involved with in the project could or might result in bias for they might not see the abnormalities or severe risks in the project. Delphi technique is a structured technique of expert judgment and is essentially a form based technique involving a multi step procedure and these are: The experts are issued the specification and estimation form by the co-coordinator, a group meeting is held to discuss the product and estimation issues, experts produce an independent estimate, estimates are returned indicating the median estimate and the expert’s personal estimate, another group meeting is held to discuss results, experts prepare a revised independent estimate, steps 3-6 are repeated until a consensus is reached by the panel of experts.
