SDLC: Agile Model

Agile model is commonly used by SDLC these days because of its adaptability to changing requirements . It is a combination of Iterative & Incremental models . It focuses on process adaptability & rapid delivery of working software products .

In Agile , requirements are divided in small incremental builds (iteration). Each build lasts for about 1-2 months . Each build is planned in advance . At the end of each build customers feedback is taken on the current build. The final build has all requirements.

Here’s the diagram of Agile Model:

Each Build has to go through Design , Development and Testing.

Check out my blog SDLC to get the gist of the process.

Use Cases

• Frequent changes are required
• Highly skilled team is available
• Customer is ready to have interaction frequently
• Project size is small

Pros of Agile Model

• Easy to manage
• Little or no planning required
• Reduces total development time
• Customer interaction is the backbone of the model
• Minimum documentation required
• Adaptive to changing requirements

Cons of Agile Model

• Not good fit for complex projects
• Risk of sustainability , maintainability & extensibility
• Heavily dependent on customer interaction . If customer is not clear then team can be guided in wrong direction
• Very high dependency on an individual since less documentation is made
• Due to less documentation passing of the project to new team members is difficult
• An overall plan and an agile expert/leader is needed without him/her the model is difficult to follow .

So far, we have discussed the Model, it’s use cases, pros & cons.
