SDLC: Agile Model

#productivity #agilemodel #softwareengineering #softwaredevelopmentlifecycle

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.
