Fit It In One Head

A Valis principle that prioritizes keeping
Work Area
and related simple enough for one person to fully understand and manage.
By respecting the
Cognitive Limit
, this principle aims to avoid
Coordination Costs
, eliminate communication overhead, and enable faster execution.
We respect the cognitive limit by:
  1. Carefully defining scopes for our work areas.
  1. Self-imposing constraints on our tooling:
      • Standardizing on a single tool, even if a specialized solution might look better in isolation. See the document.
      • Choosing not to use all features of a service. See the rule.
