Overview of Scrum Agile Development Methodology

What is Scrum?


Scrum is an agile development methodology for managing and completing projects. It is a way for teams to work together to achieve a set of common goals.

Scrum is an iterative and incremental approach to software development, meaning that a large project is split into a series of iterations called “Sprints”, where in each sprint, the goal is to complete a set of tasks to move the project closer to completion.

Each sprint typically lasts 2 to 4 weeks or a calendar month at most. Building products one small piece at a time encourages creativity and enables teams to respond to feedback and change and to build exactly what is needed.

In scrum, product is designed, coded and tested in the sprint.

A key principle of Scrum is its recognition that during a project the customers can change their minds about what they want and need (often called “requirements churn”), and that unpredicted challenges cannot be easily addressed in a traditional predictive or planned manner. As such, Scrum adopts an empirical approach—accepting that the problem cannot be fully understood or defined, focusing instead on maximizing the team’s ability to deliver quickly and respond to emerging requirements.

Scrum Framework

The scrum framework has three components: Roles, Events and Artifacts.



Product Owner

  • Defines features and release plans
  • Prioritize features every iteration as needed
  • Accept or reject work results

Scrum Master

  • Responsible for enacting Scrum values and practices
  • Ensure that the team is fully functional and productive
  • Enable close cooperation across all roles and functions


  • Cross-functional:Programmers, testers, user experience designers, etc.
  • Members should be full-time
  • Teams are self-organizing

Sprint Events

Daily scrum meeting

  • Daily review meeting for 10-15 mins
  • Status review and not for problem solving
  • All sprint team members participate
  • More on daily scrum meeting

Sprint review

  • Demo of new features to customer/product owner
  • Team presents work accomplished during the sprint
  • All major stakeholders participate

Sprint retrospective

  • Periodic post mortem to review what’s working and what’s not
  • Done after every sprint
  • All major stakeholders participate


Product backlog

  • A list of all desired work on the project
  • Ideally expressed such that each item has value to the users or customers of the product
  • Prioritized by the product owner
  • Reprioritized at the start of each sprint

Sprint Backlog

  • A list of tasks identified by the Scrum team to be completed during the sprint.
  • The team selects the items and size of the sprint backlog



Sprint Burndown Charts

  • Chart updated everyday, shows the work remaining within the sprint
  • Gives an indication of the progress and whether some stories need to be removed and postponed to the next sprint



In Summary:

  • Scrum is an agile development methodology
  • It is an Iterative and Incremental approach to developing software
  • There are three main roles in Scrum: Product Owner – Scrum Master – Scrum Team
  • Each Sprint typically lasts between 2 to 4 weeks
  • Product Owner creates and prioritizes a list of wishlist items called the product backlog
  • In Sprint Planning Meeting, the Scrum Team decides how many items from the backlog can be developed in a Sprint
  • Every day of the Sprint, the team get together and do a stand-up called the Daily Scrum Meeting
  • Testing and Development is done together rather than separate activities
  • During the Sprint, Scrum Master tries to remove any impediments and blockers so the Scrum Team can continue to work
  • At the end of the Sprint, the Team showcase the developed features, which are potentially candidates for release, to the business
  • At the end of the Sprint, there is also a Sprint Review at the Retrospective Meeting
