What do Waterfall Hardware And Agile Software Management Types Mean?

As any software project begins, the first decision that project teams have to take is to decide between the waterfall and agile model. The waterfall model follows a traditional and sequential approach whereas the agile model follows a modern and iterative model.

What is the waterfall model?

It is a sequential model in which software development is divided into pre-defined phases. In this model, the tasks are completed in order and one task is finished at a time. The work on the next task begins only after the completion of the previous task.

The stages of this model are as follows:

1. Requirement analysis- All the requirements of the system to be developed are gathered and documented in the system requirement specification document (SRS)

2. System design – Based on the SRS document, system design is prepared to understand the overall system architecture

3. Implementation – Based on the system design, the system is developed into smaller programs known as units. These units are tested and integrated known as unit and integration testing

4. System testing – Once all the units are tested and integrated, the post-integration testing whole system is again tested to ensure there are no faults or failures

5. System deployment – Once all the functional and non-functional tests are done, the system is deployed in the production environment and is released in the market

6. System maintenance – Once the system is deployed in the client’s environment, if some issues arise, the issues are fixed and patches are released. Also to enhance the system, upgraded versions are released from time to time

What is the agile model?

It is the most significant approach in project management that is used in SDLC. This approach has been introduced in the field of software development to overcome difficulties that were previously present in the waterfall model. It works on the iterative and incremental model. Processes are tailored according to the need of the specific project and customer requirements. In this model, the tasks are broken into smaller segments and teams work on these tasks based on priority within time frames knows as sprints.

The stages of this model are as follows:

Iteration 1:

  • Planning
  • Requirement analysis
  • Designing
  • Building
  • Testing

After 2-3 months, Iteration 2:

  • Planning
  • Requirement analysis
  • Designing
  • Building
  • Testing

After 2-3 months, Iteration 3:

  • Planning
  • Requirement analysis
  • Designing
  • Building
  • Testing

What are the key points of difference between the waterfall and agile model?

Waterfall model

It is a linear sequential life cycle model

It is a structured software development methodology

It follows a sequential approach

Testing is performed after the completion of the build phase

It does not anticipate change in software development requirements It allows changes in software development requirements

Agile model

It is a continuous iteration of development and testing

It is a flexible kind of software development & testing methodology

It follows an incremental and iterative approach

Testing is concurrent with the software development process

What are the advantages of the waterfall and agile model?

Waterfall model

It is a simple approach, easy to understand and use

It works well for smaller projects

It has clearly defined stages

It requires process and results to be well documented

Agile model

Realistic approach of software development

Suitable for fixed or changing requirements

It requires minimum resources

It focuses more on concurrent development and delivery. Documentation is easy

Conclusion: Today enterprises are shifting from the waterfall model to the agile model as it allows change and is comparatively better than the waterfall method. There are many differences between these two models but each of them plays a significant role in software development. Depending on the type of project and its requirements teams switch between these models. Leverage agile testing from a next-gen QA and software testing services provider to get a high-quality product with shortened time-to-market.
