Introducing the Rock Crusher.pdf

Agile software development introduced the backlog as a beautiful, powerful, and delightfully simple tool for managing variability and uncertainty in modern organizations. Unfortunately, the backlog can also be a major impediment to flow and break the value stream with substantial economic loss. This happens because our traditional model of backlog management presents the backlog as a stack of plates reservoir for the development team. Agile grew up, and now so does our model of the backlog. Based on the recently launched book The Rock Crusher (available from Amazon or the IIBA) this session introduces a flow-based model for backlog management. We explore how some organisations are managing their backlogs well, yet others struggle, show how turbulence is necessary for innovation, introduce the waste gate as a way to help focus on doing the right work and show how using a rock crusher helps maximise the value generated for our customers and stakeholders.

In project-oriented management, there is no incentive to reduce technical debt; its effects do not materialize until after the project ends. This results in application portfolios that are dead ends for the companies that created them and the constant accumulation of more legacy systems and code. 24 25

(What problem are you trying to solve through adoption of the Rock Crusher approach?) 2. Choose a value stream. (Where will the Rock Crusher reside?) 3. Identify your village. (Who will play the various Rock Crusher roles?) 4. Visualize your Rock Crusher. (How will you visualize the rocks flowing through the Rock Crusher?) 5. Establish your intake policies. (Where are the front and back doors into the Rock Crusher?) 6. Establish your Waste Gate policy. (What are your policies for disposing of or managing the rocks ejected through the waste gate?) 7. Schedule the ceremonies. (What is the cadence and attendance list for the various Rock Crusher ceremonies?) 8. Continuously improve your Rock Crusher. (How will you apply continuous improvement concepts to the Rock Crusher you are implementing?) Rock Crusher Hypothesis Why? What is the value of doing this? What problem are we solving? Why do we think this is the solution to this problem? Rock Crusher Metrics What will we measure to know if its working? Value Stream Which Value Stream is the Rock Crusher associated with?
