Dev Team Builds a Product
1. Each package contains one LEGO animal (according to a User Story) and one chocolate candy.
2. Each LEGO animal has a small label with a number affixed to it.
3. The contents don’t fall out if turned upside-down.
LEGO animal = software features
Chocolate = documentation

Sprint 1: Cyclical Value Delivery With Scrum
• Dev and Ops are silos• Everyone operates
within the boundaries of their roles.
• Sys Admin controls release schedule
• Security Scan at the end of the Sprint

Sprint 2: Optimizing the Scrum Team
•Cross-train Developers and Testers - address dev process bottlenecks.
•Move Security to the left - learn about security before implementation.

Step 1: Optimize Your Flow
Any improvement not made at the constraint is
an illusion
@DanaPylayeva This work is licensed under a Creative Commons Attribution-Share Alike 3.0 Unported License
Theory of Constraints. Systems Thinking.
1. Identify the system's constraint(s). 2. Decide how to exploit the system's constraint(s).3. Subordinate everything else to the above decision (align the whole system or organization to support the decision made above).4. Elevate the system's constraint(s) (make other major changes needed to increase the constraint's capacity).5. Rinse and Repeat!
