When the person who made a key decision, why this vendor, why this approach, why this exception was granted, leaves the team, the reasoning behind that decision usually leaves with them. What remains is just the outcome, with nobody left who can explain why it was actually the right call at the time, which makes it hard to know whether it's still the right call now.
A decision log doesn't need to capture everything. It needs to capture the reasoning behind the decisions that would be genuinely costly to lose.
The reasoning behind a decision usually leaves when the person who made it does
A decision's outcome is often documented somewhere, a contract, a config setting, a chosen vendor, and the actual reasoning behind it usually lives only in the memory of whoever made the call. When that person leaves, the reasoning is effectively gone.
Capture the why behind a decision, not just what was decided
"We use Vendor X" tells a future team member nothing about whether that's still the right choice; "we chose Vendor X because of Y and Z, and ruled out A because of B" gives them what they need to actually evaluate it later. Capture the reasoning, not just the outcome.
In Stelaah, a decision and its reasoning can be logged directly on the project or client record where it happened, so it stays connected to the real context instead of living in a separate document nobody checks. See how projects works.
Log decisions as they're actually made, not reconstructed later from memory
Reconstructing the reasoning behind a decision after the fact, especially after the person who made it has left, produces an incomplete or inaccurate record. Build logging into the moment the decision is actually made.
Note what alternatives were considered and rejected, not just the final choice
Knowing what was considered and ruled out is often as valuable as knowing what was chosen, it prevents a future team member from re-litigating an option that was already tried and rejected for a good reason. Include this briefly.
Make it genuinely searchable, not a long buried list nobody actually checks
A decision log nobody can actually find or search when they need it might as well not exist. Keep it organized and genuinely searchable, so a future team member can actually find the reasoning behind a specific decision when they need it.
A simple checklist
If you do nothing else, do these five things:
- Capture the reasoning behind a decision, not just the outcome.
- Log decisions as they're made, not reconstructed later from memory.
- Note what alternatives were considered and why they were ruled out.
- Keep it genuinely searchable, not a buried list nobody checks.
- Focus on decisions that would be genuinely costly to lose the reasoning for.
Do that, and the reasoning behind key decisions survives the person who made them, not just the outcome they left behind.
