What is SCRUM?

Adaptive, quick and self-organising

What is Srum

“The… ‘relay race’ approach to product development…may conflict with the goals of maximum speed and flexibility. Instead a holistic or ‘rugby’ approach—where a team tries to go the distance as a unit, passing the ball back and forth—may better serve today’s competitive requirements.”

Hirotaka Takeuchi and Iku j i ro Nonaka, “The New New Product Development Game”,

Harvard Bus iness Review, January 1986

What is SCRUM?

Originated in 1980s, as new new product development game out of Japan.

Agile process for managing projects

(often but not necessarily software)

Project management, not technology management.

No engineering practices (ie unit testing, continuous integration)

What is SCRUM?

Simple method for managing complex projects.

Delivering business value early and frequently.

Emperical approach, frequent inspection and adaption.

Replace illusion of predictability with a flexible approach.

Software development is not a well defined repeatable task, each task is different.

Product Backlog

Managed, controlled by Product Owner (one person).

Items originate from many sources.

ToDo list, constantly updated, and prioritzed.

Estimates added by team (for ROI), as items added.

Might be made up of simple list, might be user stories.

Example Product Backlog

Sprint

Project progresses as number of sprints.

Each sprint is typically 2 - 4 weeks. Time boxed.

No new requirements mid-sprint.

Working product delivered at the end of each sprint.

Constant duration leads to a better rhythm.

Sprint Backlog

Features to be delivered in next sprint.

Focus on features with best ROI.

Each feature split into small tasks.

Team sign up for tasks, they are not allocated.

Backlog updated to reflect progress through the sprint.

Daily Scrum (meeting)

All are welcome, but only 'pigs' may speak.

Each team member answers three questions:

What have you done since yesterday?

What are you planning to do today?

Do you have any impediments?

These are not status for the ScrumMaster, they are commitments in front of peers.
