Introduction to Scrum

Scrum is a specific framework built on Agile values. It gives teams clear roles, events, and artifacts to follow. Scrum remains the most widely used Agile framework across the software industry.

The Origin of the Name

The word scrum comes from rugby. In rugby, a scrum happens when players pack tightly together to restart play as a unit. The name suggests teamwork and tight coordination, which matches how Scrum teams operate.

The Sprint

Scrum organizes work into fixed time boxes called sprints. A sprint usually lasts between one and four weeks. The team commits to finishing a set amount of work by the end of each sprint.

Sprint 1 -> Sprint 2 -> Sprint 3 -> Sprint 4 (and so on)

Three Pillars of Scrum

Scrum rests on three pillars: transparency, inspection, and adaptation.

Transparency

Everyone involved sees the same information about the project's progress. No hidden details exist between the team and stakeholders.

Inspection

The team checks its progress and product regularly. Frequent checks catch problems early.

Adaptation

The team adjusts its plan or approach whenever inspection reveals a problem.

Layman's Example

Think of Scrum like a weekly fitness challenge with friends. Everyone shares their progress openly each week, similar to transparency. The group checks who improved and who struggled, similar to inspection. The group then adjusts next week's plan based on those results, similar to adaptation.

Key Takeaway

Scrum structures Agile work using fixed sprints and three guiding pillars. These pillars keep the team honest about progress and quick to fix problems.
