Introduction to Agile Development

Introduction to Agile Development

Agile is an iterative technique for delivering a product/software to a client by generating requirements and improving the product over time, as the name implies.

Agile software development is a Feature Driven Deployment approach that adheres to the following guidelines:

  • Customers expect continuous delivery from software developers, and they should welcome changes even late in the development process.
  • It is necessary to deploy working software on a regular basis and at short intervals.
  • Agility will be improved by paying attention to technical knowledge and strong functionality design.

In contrast to other software development models such as Traditional Waterfall methodology, where a developer receives requirements, develops the complete code, and sends it for software testing, in Agile Methodology, prioritize the requirements and collaborate with other teams to develop the given requirements while simultaneously testing the requirements that have already been completed and releasing the software.

The Scrum framework is utilized in this agile methodology to handle complicated software development using numerous processes and methodologies.

 In the scrum framework, there are three roles:


  • Scrum Master: He or she ensures that the process is followed by removing roadblocks and providing support to the development team.
  • Product Owner: He/she collaborates with stakeholders and the business.
  • Development Team: Self-organizing team that performs requirements analysis, design, implementation, and testing, among other things.

Scrum Events are a part of the Agile Methodology

Scrum is simple to grasp but putting it into practice requires more effort. Sprint, Sprint Planning, Daily Scrum, Sprint Review, and Sprint Retrospective are Scrum events in Agile methodology.

  • Sprint: A sprint is a one-month or fewer time period in which a new sprint begins immediately after the previous sprint ends. Once the sprint begins, no changes can be made, and the project's scope can be renegotiated with the Product Owner and development team.
  • Sprint planning: sprint planning is a time-box of no more than 8 hours for a month sprint that provides an overview of the needs that must be delivered in that sprint.
  • Daily Scrum: This is a 15-minute time limit event in which the development team meets to discuss and prepare for the next 24 hours in order to reduce complexity.

  • Sprint Review: At the end of each sprint, the Increment and Product Backlog are reviewed and adjusted.
  • Sprint Retrospective: This occurs after sprint review and before sprint planning to determine what went well and what may be improved in the previous sprint.

Artifacts in Agile

Product Backlog, Increment, and Sprint Backlog are examples of Agile artefacts.

  • Product Backlog: A product backlog is an organized list of needs for a product that is never complete.
  • Increment: The sum of all product backlog items completed during a sprint is called increment.
  • Sprint backlog: The sprint backlog is a collection of Product backlog items chosen for a specific sprint.


Benefits of Agile Development

  • It encourages collaboration and cross-functional training.
  • In a short period of time, functionalities can be developed and demonstrated.
  • It is a practical approach to software development.
  • The number of resources required is small.
  • Adaptable to shifting demands.
  • At least in part, early delivery of working software.
  • It's simple to use and allows developers a lot of freedom.
