VSL Software Development Process
We base on the two basic, most popular methodologies: Waterfall & Agile.
Waterfall or the traditional approach
Waterfall is a linear approach to software development. In this methodology, the sequence of events is something like:
- Gather and document requirements
- Code and unit test
- Perform system testing
- Perform internal testing
- Perform user acceptance testing (UAT)
- Fix any issues
- Deliver the finished product and go to maintenance mode
Agile is an iterative, team-based approach to development. This approach emphasizes the rapid delivery of an application in complete functional components. Rather than creating tasks and schedules, all time is “time-boxed” into phases called “sprints.” Each sprint has a defined duration (usually in weeks) with a running list of deliverables, planned at the start of the sprint. Deliverables are prioritized by business value as determined by the customer. If all planned work for the sprint cannot be completed, work is reprioritized and the information is used for future sprint planning.
As work is completed, it can be reviewed and evaluated by the project team and customer, through daily builds and end-of-sprint demos. Agile relies on a very high level of customer involvement throughout the project, but especially during these reviews.
