Delivery Models

Iterative

The Iterative delivery model focuses on incremental development and refinement. It involves repeated cycles (iterations) where a small portion of the project is developed, tested, and reviewed. Each iteration builds upon the previous one, allowing for continuous feedback and improvement. The typical steps in each iteration include:

This model is flexible and adaptive, making it suitable for projects with evolving requirements and a need for regular adjustments based on user feedback and changing circumstances.

Waterfall

The Waterfall delivery model is a linear and sequential approach to project management and software development. It consists of distinct phases, each following the completion of the previous one.

Each phase must be completed before moving on to the next, with little to no overlap. This model is best suited for projects with well-defined requirements and low uncertainty.
