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

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!
