Scrum is a simple framework for iterative product and project management, based on agile principles. The goal of scrum is to enhance the creation of value through adaptation. Work is done in iterations called sprints. A sprint is a short timebox of work, typically 1 - 4 weeks long, in which the team plans, executes, and delivers an increment of progress. Scrum is pull-based, meaning the teams are responsible for "pulling" items from the backlog to create a sprint plan. A backlog is simply a prioritized list of improvements to the product the team develops.

Scrum Roles

Scrum defines three roles:

  1. The scrum master manages ceremonies and helps remove roadblocks for the team
  2. The product owner defines and prioritizes the product backlog
  3. The developer implements the solution

A Scrum team is typically made up of one scrum master, one product owner, and roughly 5 - 10 developers.

Scrum Ceremonies

The ceremonies that happen during each sprint are:

  1. Each sprint is initiated with sprint planning, when the team evaluates the backlog and decides what will be delivered during the sprint.
  2. The team meets each day in the daily scrum to review progress from the previous day, plans for the day ahead, and known risks and road blocks.
  3. Each sprint closes with a sprint review where the team demonstrates their progress to stakeholders and collects feedback that can inform the next sprint plan.
  4. Finally, the team holds a sprint retrospective to reflect on how they can improve their interactions, processes, and tools.

Scrum Artifacts

Scrum artifacts are the output of the Scrum process. They include:

  1. The product backlog: A prioritized list of product improvements that serves as the single source of work for the team.
  2. The sprint backlog is pulled from the product backlog to create a prioritized list of improvements that can reasonably be delivered in the current sprint.
  3. An increment is the set of improvements delivered and demoed in a sprint.
