Agile Model vs. Waterfall Model


What is agile model?

Agile model combines both iterative and incremental process models. This model focuses on process adaptability and satisfying the customers by swift delivery of software product. The agile model divides the product into small incremental builds. These builds are then iterated. The time taken for each iteration is approximately one to three weeks.   

Cross-functional teams involve themselves in each iteration and see to that it is properly undertaken. Once the iteration is successfully completed, then the final product is shared to the customer for their feedback.

Advantages of agile model:

·         Teamwork and cross-training is encouraged

·         It is adaptable to both fixed and changing requirements in line with product development

·         It is suitable for product development of such products and environments where changes take place frequently

·         Simple to follow rules and an easy to understand documentation process

·         It can be easily managed without any complexity as such.

What is waterfall model?

Waterfall model follows a more sequential approach. This means that each phase of the waterfall model must be successfully completed before going on to the next phase. The waterfall model demonstrates the software development life cycle process in a linear sequential flow.

Following are the different phases of the waterfall model:

·         Requirement Analysis

·         System design

·         Implementation

·         Testing

·         Deployment

·         Maintenance

Advantages of waterfall model:

·         For every phase, there are particular deliverables to be expected and also a thorough review activity takes place

·         It is highly rewarding for small projects where requirements are clearly presented

·         All the tasks can be easily arranged

·         All the results obtained from each phase are well documented 

·         All the stages of this model are well-defined for providing productive outcomes.

Benefits of Agile Methodology 2021

Image
The software industry has been transformed by agile methodology.   Agile is being adopted by every organization in a variety of ways to meet their business needs. They also aim to be accessible to the market and their end-users.   Agile methodologies can be applied in many ways.   Agile methodology is a fast, flexible, and responsive software development process.   Many companies have customized the Agile Software Development Life Cycle to meet their specific needs. The benefits of agile methodology 1.   Collaboration and total involvement with the entire team is key: Testing allows testers to shift left during the development cycle, allowing them to work with the rest of their product team instead of being isolated entities that only enter the phase before release.   The testers have shown the evolution of their work, and how they are a great help to other teams by working together. 2.   Test automation allows for better quality work and more...

Dealing With Agile Implementation Problems

Image
  So, your working coach advised you that after you implemented , the staff growth goes through the roof. But you are trying hard to observe the outcome. Perhaps it is taking a bit longer than anticipated to arrive, or perhaps the environment you have made doesn't match the new demands. What do you need to do? Run into the trainee trainer and need your money back? Possibly, but , why don't you take a better look at exactly what factors have the maximum effect where nimble team efficacy is worried? Agile execution Issues Bad user reports Bad user reports are tales which are either poorly written in their own heart (they make no sense), are poorly rigged (development group does not understand exactly what to do), or are simply too big for a single feature or mend. A simple solution is to become in touch with the staff that's quite likely to be functioning in a product to assist when composing the consumer story. Incorrect Comprehension of time boxing The notio...
