In this Software Testing Tutorial, we will learn about the iterative model in software engineering. The iterative development model was again the improvement over the waterfall and V model in order to address the delay in feedback loop.
When we follow longer development cycles then the feedback from customer is delayed as they only see the actual working software after long development cycle.
In order to overcome this iterative development approach came in picture where the smaller development cycles were repeated in order to get quick feedback from customer after each iteration.

**Software Testing Tutorial #10 - Iterative Model in Software Engineering - Notes**
**Nature of Iterative Development:**
- The Iterative Development Model emerged as a response to previous methodologies' limitations.
- This model involves shorter cycles or iterations, each resembling a mini Waterfall Model.
- Cycles are compressed, lasting from a month to a few months, facilitating rapid value delivery.
**Iteration Process:**
- In the traditional Waterfall Model, phases like Requirements, Design, Development, Testing, Deployment, and Maintenance span longer periods.
- In the Iterative Development Model, each phase is condensed into a cycle.
- Example: Initial iteration focuses on building a login page for an e-commerce app.
- This iteration includes Requirements, Design, Development, Testing, and Deployment for the login page.
**Incremental Value Through Iterations:**
- Subsequent iterations add functionalities to the existing software incrementally.
- Enhancements like CSS improvements, "Forgot Password" feature, "Forgot Username," or social media sign-ins are introduced in successive iterations.
**Advantages and Considerations:**
- The model swiftly delivers value to customers by employing shorter iterations.
- Still follows a phased approach, where Requirements must be locked before progressing.
- Enhances speed but doesn't eliminate challenges of phased development.
**Differentiating from Agile:**
- Iterative Development shares some similarities with Agile methodologies like Scrum.
- Agile encompasses broader values and practices, emphasizing customer collaboration, adaptive planning, and flexibility.
- Iterative Development is a technique within Agile methodologies.
**Conclusion:**
- The Iterative Development Model accelerates value delivery with shorter iterations.
- Users experience incremental software enhancements within weeks.
- Doesn't eliminate phased approach but significantly speeds up software delivery.
thank you again my honorary coursemate. Worthy of your flowers. I often come to your comment post each session to see the executive summary.
@@brytespeaks6343Exactly 😂. He or she is the best
Thank you so much ❤
Thank you sir
