Scrum events and timeboxes: Sprint Planning to Retrospective

Scrum has five events: the Sprint, which contains Sprint Planning, the Daily Scrum, the Sprint Review and the Sprint Retrospective. Each is a formal chance to inspect and adapt, and each has a maximum length, called a timebox.

The events and their timeboxes

The Sprint is a fixed length of one month or less, and the next starts as soon as the previous ends. Sprint Planning sets the Sprint Goal, selects items and plans the work, in at most eight hours for a one-month Sprint. The Daily Scrum is 15 minutes for the Developers to inspect progress toward the Sprint Goal and adapt the plan. The Sprint Review is at most four hours, and the Sprint Retrospective at most three. Shorter Sprints usually have shorter events.

The Scrum Master makes sure the events take place and stay within their timebox.

Rules scenarios turn on

During the Sprint no changes are made that would endanger the Sprint Goal and quality does not decrease, but scope may be clarified and renegotiated with the Product Owner as more is learned. If one selected item turns out far larger than forecast, the Developers renegotiate scope with the Product Owner. They do not extend the Sprint or cut testing.

Only the Product Owner can cancel a Sprint, and only when the Sprint Goal becomes obsolete.

The Daily Scrum is for the Developers. If the Product Owner or Scrum Master is actively working on Sprint Backlog items, they take part as Developers. Detailed discussions can happen at other times during the day.

Review versus Retrospective

The Sprint Review inspects the product outcome with key stakeholders and decides what to do next; the Product Backlog may be adjusted. The Scrum Guide calls it a working session and says the team should avoid limiting it to a presentation.

The Sprint Retrospective inspects how the Sprint went for individuals, interactions, processes, tools and the Definition of Done, and plans ways to improve quality and effectiveness. It concludes the Sprint.

Where the exam catches people

  • Believing the Sprint can be extended to finish late work: Sprints are fixed length, so scope is renegotiated instead.
  • Believing a Sprint can be cancelled because urgent work arrived: it can be cancelled only when the Sprint Goal becomes obsolete, and only by the Product Owner.
  • Believing the Sprint Review is a demo: the Scrum Guide calls it a working session where attendees collaborate on what to do next.
  • Believing the Product Owner never attends the Daily Scrum: a Product Owner working on Sprint Backlog items takes part as a Developer.

Pick an answer to see why each option is right or wrong.

  1. Key stakeholders attend every Sprint Review but mostly watch while the Developers demonstrate features. The project manager wants their input to shape the Product Backlog. Which of the following should the Sprint Review become?

    Right. In the game that’s Renown for your People building.

    Not that one: D is right. In the game your People building would lose a little Renown, and this question would come back later.

  2. Midway through a Sprint, the Developers find one selected item is far larger than forecast, so not every selected item will be finished. Which of the following should the project manager encourage?

    Right. In the game that’s Renown for your People building.

    Not that one: A is right. In the game your People building would lose a little Renown, and this question would come back later.

  3. This Sprint, the Product Owner is also building two items in the Sprint Backlog. The Scrum Master suggests the Product Owner stay away from the Daily Scrum so the Developers can self-manage. Which of the following should the project manager encourage?

    Right. In the game that’s Renown for your People building.

    Not that one: B is right. In the game your People building would lose a little Renown, and this question would come back later.

    Show the full explanation and doc quotes

    This Product Owner is building two items, so they take part as a Developer.
