Guide on Water-Scrum-Fall Model

Importance of Water-Scrum-Fall Model:
The Water-Scrum-Fall model is crucial as it allows for more flexibility and faster delivery compared to purely deterministic models such as Waterfall, but still provide certain levels of stability. It incorporates aspects of both Waterfall and Scrum, thus adding predictability for more skittish stakeholders or high-stakes environments, while maintaining the advantages of iterative development.

What is it:
The Water-Scrum-Fall model is a hybrid agile and traditional methodology. The Design and Realization phase is iterative, therefore known as Scrum. The rest of the phases like building specifications, system setup, and going live are sequential and hence known as Waterfall.

How it works:
The Water-Scrum-Fall model begins with a determinate waterfall stage: a team defines a project’s scope and desired outcome. In the next stage, the scrum takes place. It involves iterative work cycles for developing the product. Finally, it ends with another waterfall stage where the product gets launched and reviewed.

Exam Tips: Answering Questions on Water-Scrum-Fall Model:

Assumptions: Ask yourself what kinds of projects and environments this model assumes.
Pros and Cons: Every model has strengths and weaknesses. Understand what makes the Water-Scrum-Fall Model useful and where it may fall short.
Differences: Understand the differences between a pure agile, pure waterfall, and the hybrid Water-Scrum-Fall Model.
