The Knowledge Decay Curve: Why Agency Retainers Leak Margin Between Onboarding and Offboarding

Every agency retainer carries a hidden tax: the hours spent re-answering questions that were already answered, re-documenting processes after a departure, and re-onboarding a replacement account lead. Knowledge management platforms now attack that tax directly by detecting stale documentation and auto-verifying content as usage rises, which turns a fixed onboarding cost into a compounding delivery asset. The strategic question is not whether to centralize knowledge, but whether your chosen platform plugs into the tools your team already lives in or becomes an eighteenth browser tab.
