Project Highlights

Project Highlights
There are several key highlights in this Epitrain Elearning Platform (EEP) project made by Team Cavetz.

  • Cavetz managed to protect online documents from copying or alterating. Therefore copyright protection of Epitrain's training materials is achieved, and the profit is maximized for the company.
  • Highlighting and comments can be saved on the server for the students' learning purpose. They will also be able to share the notes with a group of users.
  • Discussion forum with tagging function is developed to ensure the communication between staff and students. Staff gains a better overview of student's understanding over course content and materials.

Project Challenges
Our challenges faced includes:

  • Absense of knowledge for PHP framework Laravel. The developers are unfamiliar with the framework and the framework has many limitations and compatibility issues with the other packages.
  • Managing the front-end designs and keeping the consistency though the design is completed by various developers. Calculation of the book prices.
  • Developing differents functions for different types of users of the project.
  • Saving highlighting and comments on the server with minimal cost for the sponsor.

Project Achievements

  • Managing all Epitrain training materials on the real application.
  • Achieved 80% positive feedback from user testings on average.
  • 100% of the testers reflected that the application is easy to use and will be helpful for the students.



Technical Complexity

Shopping Cart

  • We wants a shopping cart similar to that of Amazon, but there is no existing solution on our framework, so we built one from scratch
  • Two main processes:

- Adding and checking out items
- Deleting items/the whole cart
Shopping Cart – adding items
Team CAVETZ Tech Complexity 1.png

  • View after adding books
  • Price calculation

Team CAVETZ Tech Complexity 2.png

  • Calculation of final prices is done in the view for dynamic price calculation

Team CAVETZ Tech Complexity 3.png

  • Calculation of final prices is done in the view via a phpScript

Team CAVETZ Tech Complexity 4.png

  • Removing an item from shopping cart will also dynamically update the price

Team CAVETZ Tech Complexity 5.png

  • Boilerplate function for next iteration’s ePayment module

Disallow concurrent login & automatic logout for idle users

  • Table for session data

Team CAVETZ Tech Complexity 8.png

  • Automatic logout for idle users – SessionTimeOut request handler

Team CAVETZ Tech Complexity 9.png

  • Disallow concurrent login – Authentication controller, post-login

Team CAVETZ Tech Complexity 10.png

  • Disallow concurrent login – Authentication controller, upon log out

Team CAVETZ Tech Complexity 11.png

  • Disallow concurrent login – DisallowConcurrentLogin request handler

Team CAVETZ Tech Complexity 12.png

  • Disallow concurrent login
  • Authentication controller, post-login

Team CAVETZ Tech Complexity 13.png

  • Login view page – display error messages

Project Risks

6Sigma Risk Table.png


Risk Type Risk Event Likelihood Impact Category Prevention Measures Reactive Measures
Requirement risk Some corner cases and scenarios - especially about security and publishers’ functions - may not be fully captured in the requirement gathering phase. Medium High A We will plan test cases carefully and conduct thorough testing in order to detect corner cases and minimize the number of glitches We will update requirements as the development progresses along the way to cover these corner cases.
Technology Risk There might be inconsistency in the quality of encryption on different devices or among different types of files as our team has limited experience in implementing encryption methods. To mitigate this, our team decided to consult professors with expertise in security and do research on encryption implementation of different devices. Medium Medium B We chose a framework with support for strong encryption techniques and compatible with multiple platforms (Laravel) and conducted intensive research on security standards as well as implementation methods of these methods that are suitable to our project We will consult professors with expertise in security and arrange meetings with clients for alternative options
Client Management Risk There might be misunderstanding of requirements and expectation between us and our client since they are not familiar with IT techniques and limitations. High High A The team will communicate regularly with the client to ensure that the client is satisfied with our products and to keep us on track should any change need to be made To mitigate this, we will arrange irregular meetings with the sponsor to adjust our business and IT expectations should we know that a misunderstanding is present.

Risk Measure Logs

Iteration Risk Type Event description Measures taken Status
5 Technology Clients want their macro-enabled spreadsheets to be accessed online simultaneously by 50 students. However, we have a few problems:

- Online spreadsheets application do not support macros - Online excel spreadsheet is configured by Microsoft to be accessed only one at a time (there is a locking mechanism involved that we can't change) - Spreadsheets' formulas are our sponsors' intellectual properties, thus they cannot let the students copy it out and our team has very restricted access to the spreadsheets

Meeting with client was arranged to rectify the issue. We proposed using either d3.js to stimulate the spreadsheet or to let students have offline access to it with encryption mechanism involving the users' passwords. The client chose the second method and our team decided to consult multiple professors as well as our supervisor for help regarding encryption. Completed
6 Client management Clients' requirements for us to have all our plugins and libraries resided within our platform and for our platform to call no external service wasn't made clear at the beginning at the project. Thus, they expect our ebook highlighting & annotation functions which are calling an external service (Hypothes.is) to be ported inside our application code. However, there are no available PDF highlighting & annotation plugin that we can embed in our application and our team lacks the capability and time to develop such functions from scratch. Meeting with client was arranged to rectify the issue. However since the CEO on our sponsor side couldn't be there, conversation through emails following the meeting were carried out to reach a consensus of having an exception for this ebook highlighting & annotation function. Completed

Reflection

Team Reflection

  • Throughout the duration of this project from acceptance to midterm, we have learnt the importance of open communication, being able to estimate our ability correctly and foreseeing possible technical roadblocks.


  • For communication, our perseverance in negotiating requirements for spreadsheets have paid off but on the other hand, we also encountered development setbacks due to lack of communication at certain times.


  • Regarding estimating our abilities and foreseeing technical roadblocks, we have learnt that extensive research needs to be done to prepare mitigation for everything that might go wrong, even if we think that it’s very simple.


  • We have also learnt the importance of working with one another as we have different strengths and weaknesses, which are complemented only in a group setting.
