|Severity||Low Impact||High Impact||Critical Impact|
|Description||User interface display errors, such as out of alignment, colour used is not according to theme.
It does not affect the functionality of the system.
|The system is functional with some non-critical functionalities are not working.||The system is not functional.
Bugs have to be fixed before proceeding.
|Points||BM <= 5||5 < BM < 10||BM >= 10|
|Description||The system does not need immediate fixing, could be fixed during buffer time or during coding sessions||Coders to use planned debugging time in the iteration to solve the bug||The team has to stop all current development and resolve the bug immediately|
|S/N||Risk Type||Description||Likelihood||Impact Level||Threat Level||Mitigation Plan|
|1||Project Management||The schedule is planned based on macro functionalities, so small coding tasks may have been left out / time is underestimated due to lack of experience.||Medium||High||A||Project Manager will review the project schedule and the time needed for each task regularly, and make changes when necessary.|
|2||Client Management||Client may request for changes to existing functionalities or request for new functionalities. These increases in scope may delay the project completion.||Medium||Medium||B||Team will have to consider expertise and time required. Project Manager will manage the expectations of the client.|
|3||Project Management||Team members feel overwhelmed by the workload, and feel that they are increasingly burned out.||Medium||Low||C||Team members will limit the increases in scope, and prioritize functions in case functions need to be dropped.|
Our technical complexity comprises of:
- Use of Natural Language Processing to mark open-ended questions. (Discussed here during Midterms)
- Development of game for students, including anti-cheating mechanisms. (Discussed here during Midterms)
- Security features: firewall, automated backup for database, HTTPS protocol, SSH tunnel, and encryption of environment variables. (Discussed here during Midterms)
- Analyics dashboards for Students, Professors and Admins.
- Recommendation Models for Students and Professors.
The aim of our project is to use technology to enhance students' learning. We believe that analytics dashboards are a good medium to provide the 3 types of users an overview of the matters they will be most interested in. The dashboards were designed to be interactive, to allow users to zoom in and out based on the level of detail they want. The benefits to the 3 types of users are:
- Students: The analytics dashboard will help students identify their personal strengths and weaknesses through tracking their performance, as well as comparing them with their peers. These are good indicators of which areas they need to improve on.
- Professors: Their dashboard will provide valuable information on common weaknesses amongst students. This will guide their course planning in an efficient manner, as they will not have to go through the extremely time consuming process of marking every student's response.
- Admin: The dashboard for the Admins will provide them an overview of Medsense's status. They will be able to see the number of students for each school and cohort, as well as the number of cases for each specialty and sub-specialties.
Student Recommendation Model
We have implemented a recommendation model for students, to address their individual weaknesses.This model is guided by the following principles:
- Recommend beginner/advanced cases based on year of study: Medical students in their third year and below will be recommended beginner cases, while medical students who are in the fourth and fifth year of study will be recommended advanced cases. This is in accordance with their curriculum in school.
- Recommend most popular cases for new users: A new user might feel overwhelmed with the selection of cases. Hence, we will recommend the popular cases for them to familiarize themselves with the games. Their performance in these popular cases is a good gauge of their personal strengths and weaknesses, and will serve as a starting point for more targeted recommendations in the future.
- Recommend cases in the sub-specialties they are weakest in, based on the cases they have previously done: Through our model, we aim to tailor instruction to individual learner's needs. By recommending students to practice on topics they are weaker in, we believe that the medical students will be able to learn in a more holistic manner.
Professor Recommendation Model
For Professors, knowing which areas students are commonly weak in will assist them in their course planning. We would like to encourage Professors to upload more cases on the students' weaker topics. The recommendation model is guided by the following principles:
- The recommended sub-specialties are based on the overall cohort performances.
- Recommend sub-specialties with the least number of cases if there is insufficient data to determine the weaker topics: Professors will not be able to gauge students' performances in areas where there are no cases for students to try. The model will encourage them to upload cases in those sub-specialties, so that they can get a more accurate idea of the students' weaknesses.
- Recommend sub-specialties where the number of pending cases is above a certain threshold: Doing so will encourage Professors to vet the pending cases, which will increase the number of cases for students to practice on.

Our team has learnt the importance of working together closely with our clients, to ensure an ideal alignment between the client business requirements and our end-product. Throughout our development process, we are constantly plagued with minor hiccups and bugs. However, our team feels that our most valuable quality is resilience, as we tackle each and every problem with our ineffable tenacity and innovation.
It has been a very experimental journey managing the team since the project started. New challenges are always popping up, and I have learnt to manage the workload of each member more carefully. I believe communication is today’s important skill, be it raising issues with the team or simple dissemination of information. That is why I ensure that there are no communication lapses in our team.
It has been a challenging 7 weeks since our acceptance. The application architecture has undergone multiple major changes, especially our security configrations, to ensure better quality and continuity for our clients. The security breach incident was an eye-opening experience for me, and I have learnt to never take security for granted. I have realised that security should be a key consideration when planning an application's architecture because every implementation or change made could introduce a new vulnerability for potential attackers to take advantage of. Aside from the security enhancements, I have also discovered the difficulties in planning a software architecture after taking into account of budget, skill and technical constrains.
Being the previous Business Analyst, it was an enriching and mind-boggling experience researching on various Natural Language Processing techniques and trying to appraise their adequacy and appropriateness for our application. Moving on as the Quality Assurance lead, I hope I do not offend everyone involved in development by scrutinizing every single corner case in the application.
The opportunity to be able to apply the entire design thinking process from the creation of prototypes to the actual web development have been arduous but rewarding journey. The final designs of the application are a product of multiple revamps, each better compared to the previous. I have learnt the importance of gathering feedback from the clients as well as real users.
Having to pick up Node.js and React.js in a short period of time really pushed me to learn and adapt at a much faster pace. There are many front-end and back-end considerations to factor in during the design process, such as the communication between parent-child components and the use of redux store versus a direct http request to the database. I believe that my technical skills have definitely improved over the past few weeks.
It has been a great experience seeing how the project has grown from infancy to where it is today. As a backend developer, I have realised that is important to have a seamless integration of the frontend components with the server side logic as well as designing and implementing data storage solutions. Throughout the past few months working on the project, I have learnt that what’s even more important than completing the work assigned to me is to help my team members with their tasks. This will enable smoother and faster progression as a team.
