Throughout our FYP journey, we have tried our best to implement the changes that our clients have requested, even if it meant additional coding hours or having to rework the project schedule multiple times. This is because we place emphasis on our project's value to the clients. However, as we approach the completion of our project, we had to scrutinize every change more closely. We had to find a balance between providing the best value to the clients, as well as our workload and confidence of completing the project in time.  
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.

Our stakeholders have been actively involved in our project right from the start. Apart from meeting our supervisor regularly, we have been in constant communication with our other stakeholders. Working with a team of 17 entails certain challenges. I have learnt to manage different perspectives and expectations, as well as balance the workload and priorities of my team.  
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.

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.

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.

This will enable smoother and faster progression as a team.

Project Risks:

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.



Technical Complexity:

Our technical complexity comprises of:


Recommendation Models

Student Recommendation Model

We have implemented a recommendation model for students, to address their individual weaknesses.This model is guided by the following principles:

  1. 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.

  2. 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.

  3. 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:

  1. The recommended sub-specialties are based on the overall cohort performances.

  2. 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.

  3. 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.
