Project Management

The Vivapp project was developed using an agile method, with two-week sprints. Every day, the team would gather for a few minutes during the daily meeting to discuss each person's progress or achievements, the work planned for the day, and any issues encountered. At the end of each sprint, there was a production release, a product demo, and a team retrospective to discuss what worked well, what didn't, and to implement corrective actions for three improvement points selected by the majority vote of the team members. During each sprint, there was also a sprint planning and a sprint review. The sprint planning, led by the Product Owner, aimed to select tasks from the backlog for the next sprint and estimate their complexity using the Fibonacci sequence. A task ready to be selected for a sprint must have a Definition of Ready and a Definition of Done. Every two weeks, a developer from the team participated in a session with the UX team to review the Figma mockups and give their feedback and improvement ideas.
