Example of Agile Software Development
Let’s go through an example to understand clearly how agile works. A Software company named ABC wants to make a new web browser for the latest release of its operating system. The deadline for the task is 10 months. The company’s head assigned two teams named Team A and Team B for this task. To motivate the teams, the company head says that the first team to develop the browser would be given a salary hike and a one-week full-sponsored travel plan. With the dreams of their wild travel fantasies, the two teams set out on the journey of the web browser. Team A decided to play by the book and decided to choose the Waterfall model for the development. Team B after a heavy discussion decided to take a leap of faith and choose Agile as their development model. The Development Plan of the Team A is as follows:
- Requirement analysis and Gathering – 1.5 Months
- Design of System – 2 Months
- Coding phase – 4 Months
- System Integration and Testing – 2 Months
- User Acceptance Testing – 5 Weeks
The Development Plan for the Team B is as follows:
- Since this was an Agile, the project was broken up into several iterations.
- The iterations are all of the same time duration.
- At the end of each iteration, a working product with a new feature has to be delivered.
- Instead of Spending 1.5 months on requirements gathering, they will decide the core features that are required in the product and decide which of these features can be developed in the first iteration.
- Any remaining features that cannot be delivered in the first iteration will be delivered in the next subsequent iteration, based on the priority.
- At the end of the first iterations, the team will deliver working software with the core basic features.
The team has put their best efforts into getting the product to a complete stage. But then out of the blue due to the rapidly changing environment, the company’s head came up with an entirely new set of features that wanted to be implemented as quickly as possible and wanted to push out a working model in 2 days. Team A was now in a fix, they were still in their design phase and had not yet started coding and they had no working model to display. Moreover, it was practically impossible for them to implement new features since the waterfall model there is not revert to the old phase once you proceed to the next stage, which means they would have to start from square one again. That would incur heavy costs and a lot of overtime. Team B was ahead of Team A in a lot of aspects, all thanks to Agile Development. They also had a working product with most of the core requirements since the first increment. And it was a piece of cake for them to add the new requirements. All they had to do was schedule these requirements for the next increment and then implement them.
Agile Software Development – Software Engineering
Agile Software Development is a software development methodology that values flexibility, collaboration, and customer satisfaction. It is based on the Agile Manifesto, a set of principles for software development that prioritize individuals and interactions, working software, customer collaboration, and responding to change.
Agile Software Development is an iterative and incremental approach to software development that emphasizes the importance of delivering a working product quickly and frequently. It involves close collaboration between the development team and the customer to ensure that the product meets their needs and expectations.
