Is Agile a STLC model?

Agile is not a Software Testing Life Cycle (STLC) model. Instead, Agile is an iterative and incremental approach to software development that emphasizes flexibility, collaboration, and continuous improvement.

Here are some key reasons why Agile is not an STLC model:

1. Scope: Agile encompasses the entire software development process, from requirements gathering to deployment and beyond. It emphasizes iterative and incremental development, customer collaboration, and responding to change. In contrast, STLC is focused solely on the testing phase within the development lifecycle.
2. Iterative Development: Agile methodologies, such as Scrum or Kanban, involve iterative development cycles, with frequent releases of working software. Each iteration includes all phases of the development process, including planning, analysis, design, implementation, testing, and deployment. STLC, on the other hand, focuses specifically on the testing phase and its associated activities.
3. Cross-Functional Teams: Agile encourages collaboration among cross-functional teams, including developers, testers, and stakeholders, to deliver value incrementally and continuously. STLC, while it involves various testing activities, does not necessarily involve the same level of cross-functional collaboration as Agile.
4. Customer Collaboration: Agile methodologies prioritize customer collaboration and feedback throughout the development process to ensure that the delivered software meets the customer’s needs and expectations. STLC focuses on verifying and validating the software’s functionality and quality through testing activities but may not necessarily involve direct customer collaboration to the same extent as Agile.
5. Adaptability: Agile methodologies are highly adaptable and allow for flexibility in responding to changing requirements and priorities. Agile teams can adjust their plans and strategies based on feedback received during each iteration. STLC, while it may incorporate some level of flexibility, is typically more structured and follows a predefined set of testing activities and processes.

In summary, while Agile and STLC are both important components of the software development lifecycle, they serve different purposes and focus on different aspects of the development process. Agile is a development methodology that emphasizes flexibility, collaboration, and iterative development, while STLC is a testing process that focuses specifically on verifying and validating the software’s functionality and quality through testing activities
