Complexity

Complexity is the amount of things you’ve to keep in mind before/when doing something. There are two types of complexity: accidental complexity and essential complexity. It is the job of the product organization to drop complexity.

Why it matters: As a system grows, it becomes complex. You should care about it because Complexity slows down execution. Hence, ruthlessly identify and shed as much accidental complexity as possible.

How to handle it

• Always do pre-mortem to breakdown information you’ve into: Known Knowns (Facts), Known Unknowns (Uncertainties or Questions), Unknown Knowns (Blindspot or Intuition), Unknown Unknowns.
• Be on the lookout for Wicked Loops
