Project Management

Project Schedule (Plan Vs Actual):


TeamXcellence planned vs actual v7.jpg


For summary of Plan Vs Actual per iteration before mid-terms, please refer to here.
Summary of Plan Vs Actual per iteration (after mid-terms):

  • Iteration 8
    • The focus was on UAT refinements and Mid-Term Presentation.
    • Everything went as planned and Mid-Term Presentation was awesome.
    • Prof Marcus was able to get the R script connector for ISES Statistical Model done on the day of Mid-Term Presentation. (The connector is for ISES to pull the completed projects responses and answers, and passes through their statistical model, and insert back the calculated results back to our database.)
  • Iteration 9
    • After post mid-term review with supervisor and sponsor, there were a few UI refinements to make on the web application, visualizations and survey app.
    • There were additional functionalities - client view all surveyor details, client preview questionnaire questions, surveyor admin bulk upload surveyors - added too.
    • There were issues with the Survey App and question logic, hence this iteration had cater time to get it fixed.
    • There was a day delay in this iteration:
      • Reason: There were issues on the uploading of questionnaire with question logic in the web application and integrating the question logic with the Survey App. It took us longer than expected to resolve.
  • Iteration 10
    • Creating the 1min video pitch task was inserted early in this iteration after receiving the email
    • Everything went as planned despite the insertion of task.
    • UAT 2 was split into two days because some clients could not make it on the day that we had planned for. This did not have much impact on us and the schedule.
    • On 30th Oct 2014 (1 day before UAT 2), we received a news from ISES that they had temporary removed our access rights to their server. They found out that there was a hacker trying to poke into their server every now and then. Hence, this breach of security incident forced ISES to take necessary actions.
      • Impact: We could not deploy our latest codes up to their server prior to UAT 2. It did not affect UAT 2 because we were able to continue to use our AWS EC2 staging environment to conduct the test.
      • Impact: The planned load test might have to be cancelled or postpone if the access rights is not given.
  • Iteration 11
    • GOOD NEWS! On 10th Nov 2014, ISES was comfortable to give us restricted access rights to tomcat server and mysql server for deployment.
    • Load Test can be conducted as planned.
    • Live Deployment
      • There were many clients indicated interest to come onboard myCSISG. However, ISES confirmed that though clients have indicated interest, clients may not come onboard within our project time frame.
      • ISES are approaching as many clients as possible to see if any clients can come onboard within the project time frame.
      • To mitigate the risk of no clients coming onboard, our team decided to use the applications to run 1 projects. The project will understand the customer satisfaction of 1 stall from F&B industry. Thus, this project was live on 17th Nov!
  • Iteration 12
    • Last lap of IS480 to finish final presentation and end of with poster day! :)

Quality:

We have the following points to ensure quality of the project:

First, we have designed our solution to comprise of 3 different portions. The first portion is the database. All read/write operations will occur on this database. The second portion is the web service which contains all the logic needed for the myCSISG portal and Survey App. We exposed the web services as REST for consumption. Furthermore, if needed, the logic in the web service will communicate with the database for read/write operations. The third portion is the front-end applications (myCSISG portal and Survey App) which consume the exposed REST web service. The combination of the 3 portions follows the concept of Model-View-Controller where View is the front-end, Controller and Model are the web service and database. This greatly reduces the possibility of code redundancy because the front-end applications could share the same web service if the functionality is the same. Moreover, this vastly reduces the complexity of maintaining codes since the front-end and back-end are separated.

Second, we uses a staging environment and live server environment. AWS EC2 is used as the staging environment for us to deploy and test, ensuring that everything is working before pushing it to the live server environment. This allowed us to identify bugs without affecting the deployed applications in the live server.

You can refer to our architecture diagram to understand about first and second point.

Third, through prototyping and user tests, we are able to evaluate feedback and iteratively incorporate the changes to ensure the usability of the myCSISG portal and Survey App.

Lastly, load test was conducted to measure the performance of the applications and server. However, due to not having the rights to configure ISES server, we could only make recommendations for them.

Testing:

We have conducted 2 User Acceptance Test, 1 A|B Test Experiment and 1 Load Test. Click here to view any of the tests information.

Here's a quick summary of each of the test conducted:

  • UAT 1
    • 10 real ISES clients kindly participated
    • The objectives were to align ISES's expectation with our current product, better understand the real user's needs and identify areas to enhance their experience with myCSISG.
    • View more about UAT 1 here
  • UAT 2
    • 6 real ISES clients kindly participated
    • The objective was to understand if myCSISG web application and survey app is ready for commercial use by ISES clients
    • View more about UAT 2 here
  • A|B Test Experiment
    • 30 participants are selected on the basis that they have done a survey within the last 3 months
    • The objective was to determine which layout (Keypad vs Slider) will help surveyors be efficient and accurate
    • View more about A|B Test Experiment here
  • Load Test
    • Load test was conducted on the live deployed site residing in ISES server
    • The objective was to understand the performance of the web application and survey app residing in ISES server. We will recommend ISES a set of changes to make to improve the performance since we do not have the permissions to make the necessary changes.

Reflection

Team Reflection:

The team has learnt that communication is one of the key factors to the success of the project. This is important as communicating ideas across to various stakeholders allowed us to better manage the project and align our goals with the clients’ expectations. Knowing that there is limited time, we have learnt to evaluate our options and solutions, and arrive at a decision that best align with the goals set forth. Lastly, we have learnt to adapt to unexpected situations and be prepared for exceptions to happen.

Teng Rui Jie Andy Reflection:

I have learnt two key lessons – communication and ability to adapt. Being able to communicate ideas clearly and concisely with various stakeholders is vital to the success of the project. Furthermore, picking up the skill to adapt to different situations has allowed me to manage the project better and react to unexpected situations better.

Tan Si Yu Reflection:

Throughout the course of this project, I have learnt to better manage client’s expectation and to deliver a solution that is truly built on the needs of its users. I have also ventured out of my comfort in terms of individual competencies and learnt to better deal with unexpected situations to bounce back even stronger.

Wong Wei Xiong Reflection:

If you want to complete the project on time don’t waste time on ideas that are far beyond the budget, your capabilities, or the client’s resources.

Weng Xinyong Reflection:

There are always trade-offs for everything. There are no perfect solutions for any given problem. Learning to evaluate on the pros and cons of each solution is important as there is no time to do everything.

Lek Guan Zhou Reflection:

Communication is the key to make a project successful; be it within teammates or other stakeholders. Through these tough 15 weeks, I have learnt how to express thoughts, more proactive in giving opinions and more open in receiving suggestions. Surely, the project had crafted me to be a much better developer as well as a team member.

Chua Zhen Ling Reflection:

Through this journey, I have learnt how to manage all the stake holders’ expectations, including my own, together in one single project. Basically, everyone has got different expectations be it individually or for another. The key is to constantly do a cost benefit analysis and most importantly, patience and tolerance. I have also learnt much from the technical executions as well as gaining more knowledge in tackling real world problems and unforeseen circumstances.
