Decision Decay

Every decision a team makes carries context: the alternatives considered, the constraints at the time, the data reviewed, and the people involved. Decision decay happens when this context is never recorded or slowly becomes inaccessible. Within weeks, the team remembers what was decided but not why.

The consequences of decision decay are costly. Teams revisit settled questions because no one can recall the original reasoning. New team members reverse past decisions without understanding the tradeoffs that were already evaluated. Leaders lose confidence in their own decision-making history, leading to slower and more cautious choices.

Preventing decision decay requires a system that captures not just the outcome of a decision, but the reasoning, the alternatives rejected, and the people involved. Decision logs, architecture decision records (ADRs), and organizational memory tools like Reattend, which captures decisions with their reasons as people work, keep this context accessible months or years later.
