In short
Program memory is a record of what drifted on a program, why, what was done about it, who approved it, and whether it worked. Most teams do not have one: the lessons live in people's heads and leave with them. With it, the next program can be warned when a known pattern starts to repeat.
Where does the knowledge go today?
Into a retrospective document that few people read, and into the memory of the people who were there. When they change teams, the knowledge goes with them.
What makes a memory useful rather than a log?
Cause and result. An event log says a milestone moved. A useful record says why it moved, what was tried, and whether that worked — a post-mortem written while it happens.
What can it answer?
Questions nothing else can:
- Which hand-offs slip, by how much, and under what conditions.
- Whose estimates hold, and which are consistently optimistic, phase by phase.
- Which fixes preserve a milestone, and which only move the slip downstream.
- Which evidence actually predicts a gate passing.
Who owns it?
You do. Tymeline keeps the record in your tenant. No model that leaves your tenant is trained on your program data.
