Scrum Theory


Scrum (n): A framework within which people can address complex adaptive problems, while productively and creatively delivering products of the highest possible value. (2)


Definition of Scrum

  • Framework not Methodology (1)
  • Servant Process not Commanding Process (1)
  • Goal = to optimise and control the creation of valuable software (1)

Origins in New New Product Development Game

  • Demonstrated complex product success
  • By self-organising team
  • The team were given objectives, not tasks (tasks make teams blinkered) (1)

House of Scrum

HouseofScrum

created by Gunther Verheyen (1)

  • The walls are the main activities of Scrum (inspect and adapt)
  • The foundation for the activities is transparency
  • The roof keeps the house safe (the increment) from the unpredictable from outside the house
  • Inside the house is the space to create (including the principles, rules, roles)

Increment

Inspect (2)

  • Frequent inspection of artefacts and progress toward Sprint Goal
  • To see if there is variance between where we are and where we want to be
  • Not too frequent to get in the way of work
  • Performed by skilled team members at the point of work

Adapt (2)

Transparency (2)

  • Artefacts of the product must be visible to all people responsible for the product
  • Common understanding
  • Example is the definition of done

Empiricism

Empiricism: "Empiricism asserts that knowledge comes from experience and making decisions based on what is known." (2)

Empirical Process Control (1)

Closed Loop System

Closed Loop System (Empirical Process)
  • Actual outcome is regularly compared with desired outcome to diminish undesired variance
  • Creates transparency
  • The Sprint and Daily Scrum are examples
  • Self-correction is applied (no need to know the details up front)
  • Complexity means steps and tasks are not predictable as they are not repeatable

Open Loop System

Techniques

Scrum Improvements Exercises

Scrum Elements Team Exercise (3)

  1. Write each element of the Scrum Framework on a separate sticky
  2. Write complementary practices the team uses on a different coloured sticky (e.g. story points)
  3. Score each sticky from 1 (not doing this) to 5 (mastered this)
  4. Discuss how the team can get each Scrum element to 5. Are the complementary practices getting in the way?

Scrum Across the Organisation (3)

  • Gather the Scrum Masters together
  • Use the liberating structure, 15% Solutions to answer the below question
    • ‘What’s within my control that I can change to get our organisation 15% closer to where it needs to be?’
