Why keep a Decisions Log?

• Decisions compound on eachother.
• Recording decisions makes it easier to onboard new team members.
• Progress requires a series of decisions: they should be recorded and searchable.
• Memory lies, a log doesn't.
• Good decisions deserve to be repeated, not rediscovered.
• Alignment happens faster when everyone can see the why behind the what.
• Feedback loops work better if everyone can explore past thinking.
• Documenting choices means never needing to ask "what did we decide?"
• Teams move faster when the context is written down, not siloed in someone's head.
• Accountability gets easier when decisions aren't ephemeral.
• Clarity beats chaos.
