On-demand Catering Service: To expand its restaurant franchise business, McDean is now offering catering service to its customers. Customers may order food three hours before an event, and the food will be delivered to customers on time. Customers may order online or on a mobile app. To increase sales among young adults, McDean is offering to waive its delivery fee if customers present their eCoupons upon delivery. To shorten your development time, your team has decided to hire three full time software engineers and three interns from UWB at the beginning of the project. Your team has also agreed to use the latest web development frameworks (e.g., Django) and technologies which can automatically generate some of the code. Your team will also coordinate with another team who is working on the backend database. Which SDLC should you use for this?

To select the most suitable SDLC (Software Development Life Cycle) for this project, you need to consider various factors such as project size, requirements, team size, timeframe, and coordination with other teams. Based on the given information, I would recommend using the Agile SDLC.

The reasons for choosing Agile SDLC in this scenario are as follows:

1. Time-to-market: Agile methodologies, such as Scrum, emphasize delivering working software in short iterations called sprints. This approach allows for quicker release cycles and faster time-to-market, which is essential for a project aiming to expand business and capture market share.

2. Flexibility and adaptability: Agile methodologies are known for their flexibility and adaptability to changing requirements. Since this is a new service offering, there might be evolving needs and scope changes. Agile allows you to accommodate these changes more easily compared to other SDLCs.

3. Collaboration and communication: Agile methodologies place a strong emphasis on communication and collaboration within the development team, as well as with stakeholders. Since your team is coordinating with another team for the backend database, Agile will enable regular interactions, feedback, and transparency, ensuring smooth coordination and alignment.

4. Incremental development: Agile encourages iterative and incremental development, where the project is divided into smaller feature sets or user stories. As you are using the latest web development frameworks and technologies that can automate code generation, an incremental approach will allow you to deliver value early on and continuously improve the application.

5. Team composition: Since you have a mix of three full-time software engineers and three interns, Agile methodologies can provide a suitable framework for teamwork, collaboration, and mentoring. The Agile approach allows for regular feedback and knowledge sharing, which can benefit both the interns and the full-time engineers.

In conclusion, considering the need for speed-to-market, flexibility, collaboration, and incremental development, Agile SDLC would be the most suitable choice for this on-demand catering service project.
