Scope (Planned Vs Actual)

Prime Scope BeforeAfter.png

Version 1 (Original)

  • Features are categorized in priority circles:
  • Core, Secondary and Tertiary Features: Features which will be developed by Prime during IS480
  • Good-to-have Features: Features which are of lower priority and can be implemented in future beyond this project

Version 2

  • Manage Students’ Progress was re-prioritised as a Tertiary feature since it is not the main focus of the IS480 project.
  • It was further re-prioritised as a Good-to-Have feature so that we can have a more manageable scope.

Version 3 (Latest)

  • Manage Reviews and Manage Users’ Reviews was replaced with Manage Evaluations

Project Metrics

Schedule Metric

The team has completed 5 sprints thus far, as shown in the burn down charts below.

Sprint 3:

  1. During December, the team met up every Monday to Thursday to complete tasks assigned. On 21 Dec, the calculated schedule ratio indicated that the team was behind schedule. We found out that the Manage Search (Instructors) feature needed more time to be completed. To get back on schedule, the team decided to shift the Manage Reviews feature to Sprint 4.
  2. On 27 Dec, the logic for Manage Search (i) feature was working but the feature had many alignment issues. The team also realised that we were behind schedule. To get back on track, we shifted the Update feature for Manage Class Registration to Sprint 4.

Sprint 4:

  1. On 10 Jan, the team met Dr. Miles Gilman (Entrepreneur-in-Residence, SMU Institute of Innovation and Entrepreneurship) for advice on improving our business plan for the ACE Startup Grant application.
  2. On 11 Jan, we consolidated all the changes to be made and realized that there were many changes to be made. The burndown chart also indicated that we were behind schedule. Hence, for the next 4 days, we dedicated much time and effort to get back on track. We decided to put our focus on the ACE submission which was in two weeks' time, therefore we shifted two features (Manage Recruitment and Manage Swim Schools) to future sprints.
  3. Since then, the team made slow progress on the features and eventually on 17 Jan, the burndown chart indicated that we were running behind schedule. The team decided to shift another two features (Manage Instructors and Manage Users) to future sprints.
  4. On 19 Jan, the burndown chart once again indicated that we were running behind schedule. The team decided to shift the Manage Notifications feature to future sprints.
  5. On 23 Jan, the team met with our supevisor Prof Lin Mei. After taking her feedback into consideration, we decided to replace the Manage Reviews feature and Manage User Reviews feature with Manage Evaluations which will be done at a later sprint.

Sprint 5:

  1. From User Test 1, the team collected much valuable feedback from the participants and wanted to implement as much feedback as we could. Hence, we put much focus into doing this at the start of the sprint.
  2. On 11 Feb, the team finalized the storyboarding based on the user test feedback, and realized that we needed more time to make changes. Since then, the team started moving away from the ideal progress line.
  3. On 17 Feb, the burndown chart indicated that the team was behind schedule. The team had an urgent meeting on 18 Feb to discuss our possible options. The outcome of the meeting was to prioritize the changes to be made from the user test feedback. We also managed our expectations for the remaining features before midterm.

Total Bug Score

  1. The chart above shows the corresponding bug severity score with the number of bugs found in each sprint.
  2. The bug severity score in Sprint 3 was the highest out of all sprints due to the testing for User Test 1 as mentioned above.
Total Bug Score Action to be Taken
< 5 Developers resolve issues within the sprint.
5 - 9 Resolve the bugs during the planned debugging time.
≥ 10 Stop current development and resolve the bugs immediately.

Change Request Management


  1. If the priority is a MUST, we will implement the change
  2. If the priority is a SHOULD and the time to implement the change is VERY SHORT, SHORT, or MEDIUM, we will implement the change.
  3. If the priority is a COULD, and the time to implement the change is VERY SHORT, we will implement the change.
  4. If the priority is a WON'T, then we will not implement the request.

Project Risks

The top 3 risks are prioritised as follows::

Risk Probability Impact Mitigation
Many issues might be raised during user tests; time is required to rectify these issues High Medium Create a response plan document to help us decide whether to implement a change based on priority, complexity and time needed to rectify the issues.
Project contains numerous documentation and different versions. Inefficent access to a particular document. Low Medium Use a collaborative file management software (e.g. Google Documents, Dropbox) to organise respective folders of the project. Consensus amongst team members to adhere to proper version labelling.
Putting too much focus on fixing user interface issues compared to ensuring the system logic is working properly High Medium Prioritize the task according to the criteria and strike a balance between the two.

Testing Methodology

Collecting of Qualitative Metrics

  1. Participants are encouraged to think aloud their thought process as they are performing each task. For example, we would encourage them to say whatever they are looking at, thinking, doing, and feeling as they go about the task. This enables us as the observer to better understand each participant’s thought processs and see first-hand the process of him/her completing the task.
  2. Facilitators will observe for usability issues during the testing procedure by recording down what participants say. The test sessions will also be video-recorded on Screen Flow so that we can go back and refer to what participants did and how they reacted.
  3. In addition, after participants have completed the user test, they will be asked to do a satisfaction level survey that will aid in the collection of qualitative metrics.

Collecting of Quantitative Metrics

  1. The amount of time taken to complete each task
  2. The number of clicks taken for each task

Registered Users



Solution: Place Login and Register in the same area and allow switching by tabs.


Solution: Change the View link to a button so users know that they can click on it to view the instructor’s profile

Based on the user feedback, we found out that users are mostly receptive to the idea of a swim-related search portal.

The top 2 favourite functions identified by the users were the Manage Search function and the Manage Notification function. They commented that the search function was easy to use and could be very useful to them. The notification function is also something they felt is lacking in the industry now. This is because they have made wasted trips to the swimming complex on the lesson day only to find out the lesson was cancelled.

The function that had the highest amount of users indicating that they are unlikely to use is the Instructor Review feature. They explained that they would not want to go through the trouble to register an account just to write a review for the instructors. However, they would not mind writing if given the option of a simpler and more convenient alternative.

A user also commented that he preferred to register classes with the instructor in person instead of registering online because he could infer the instructor’s character and personality through the former. A possible solution is to include a short introduction video clip of each instructor so that users are able to gauge the instructor for themselves through the video.

In conclusion, many users expressed that they portal is user-friendly and would be very useful to them.



Use radio buttons instead of dropdown list.


Display only the student name and contact number.
Instructors can choose to click on the student's name to view the rest of their information.

It was hard for us to get instructors to test our system because they are usually busy all the time while they are at the pool. They will either be teaching a class, or be on duty as a security guard. Thus, we only managed to get 2 instructors testers during their lunch break period when the weather is typically too hot to conduct a swim class.

Both instructors found the portal user friendly and did not face any problem using the portal. They provided mostly aesthetics feedback, such as the student list is too cluttered and the login button is too small. In addition, an important point which they commented was that since they are always on the go, they preferred to use the system on their smartphone rather than in front of the computer.
