Steps in the Agile Model
The agile model is a combination of iterative and incremental process models. The steps involve in agile SDLC models are:
- Requirement gathering
- Design the Requirements
- Construction / Iteration
- Testing / Quality Assurance
- Deployment
- Feedback
- Requirement Gathering:- In this step, the development team must gather the requirements, by interaction with the customer. development team should plan the time and effort needed to build the project. Based on this information you can evaluate technical and economical feasibility.
- Design the Requirements:- In this step, the development team will use user-flow-diagram or high-level UML diagrams to show the working of the new features and show how they will apply to the existing software. Wireframing and designing user interfaces are done in this phase.
- Construction / Iteration:- In this step, development team members start working on their project, which aims to deploy a working product.
- Testing / Quality Assurance:- Testing involves Unit Testing, Integration Testing, and System Testing. A brief introduction of these three tests is as follows:
- Unit Testing:- Unit testing is the process of checking small pieces of code to ensure that the individual parts of a program work properly on their own. Unit testing is used to test individual blocks (units) of code.
- Integration Testing:- Integration testing is used to identify and resolve any issues that may arise when different units of the software are combined.
- System Testing:- Goal is to ensure that the software meets the requirements of the users and that it works correctly in all possible scenarios.
- Deployment:- In this step, the development team will deploy the working project to end users.
- Feedback:- This is the last step of the Agile Model. In this, the team receives feedback about the product and works on correcting bugs based on feedback provided by the customer.
The time required to complete an iteration is known as a Time Box. Time-box refers to the maximum amount of time needed to deliver an iteration to customers. So, the end date for an iteration does not change. However, the development team can decide to reduce the delivered functionality during a Time-box if necessary to deliver it on time. The Agile model’s central principle is delivering an increment to the customer after each Time-box.
Agile Development Models – Software Engineering
In earlier days, the Iterative Waterfall Model was very popular for completing a project. But nowadays, developers face various problems while using it to develop software. The main difficulties included handling customer change requests during project development and the high cost and time required to incorporate these changes. To overcome these drawbacks of the Waterfall Model, in the mid-1990s the Agile Software Development model was proposed.
