We’re losing the relay race

Hirotaka Takeuchi and Ikujiro Nonaka, “The New Product Development Game”, Harvard Business Review, January 1986.

“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

Product owner

Define the features of the productDecide on release date and contentBe responsible for the profitability of the product (ROI)Prioritize features according to market value Adjust features and priority every iteration, as needed Accept or reject work results

The ScrumMaster

Represents management to the projectResponsible for enacting Scrum values and practicesRemoves impediments Ensure that the team is fully functional and productiveEnable close cooperation across all roles and functionsShield the team from external interferences

The team

Typically 4-9 peopleCross-functional:

Programmers, testers, user experience designers, etc.

Members should be full-timeMay be exceptions (e.g., database administrator)

Teams are self-organizingIdeally, no titles but rarely a possibility

Membership should change only between sprints

A sample product backlog

Backlog item EstimateAllow a guest to make a reservation 3

As a guest, I want to change the dates of a reservation. 3

As a hotel employee, I can run RevPAR reports (revenue-per-available-room) 8

Improve exception handling 8... 30... 50

Sprints

Scrum projects make progress in a series of “sprints”

Analogous to Extreme Programming iterationsTypical duration is 2–4 weeks or a calendar month at mostA constant duration leads to a better rhythmProduct is designed, coded, and tested during the sprint

Sprint planning

Team selects items from the product backlog they can commit to completingSprint backlog is created

Tasks are identified and each is estimated (1-16 hours)Collaboratively, not done alone by the ScrumMaster

High-level design is considered
