Any team whose best answers live in someone's memory. The evidence is usually in a file; the person who needs it can't find it in time.
Consulting and professional services
"Which past projects are like this RFP?"
Comparable engagements, their outcomes, and the people who did the work, cited from the proposals and close-out reports you already have.
Clinical research site networks
"Can we run this protocol?"
Investigators who have run the indication, real enrollment against commitments, the equipment the procedures need, and the gaps.
Sponsors and CROs
"Which sites delivered on enrollment last time?"
Every site you have worked with, what it committed, what it randomized, and what the monitoring reports flagged, before the next selection round.
Investment and deal teams
"Have we looked at this company before, and why did we pass?"
Deal memos, committee notes, and diligence findings, so the reasoning survives the person who wrote it.
Agencies
"Which pitches did we win in this category?"
Pitch decks, case studies, and win-loss notes by sector and service, with what was shown and what the client said.
