Action, not just insight

Each finding lands with a recommended next move and the evidence behind it.

What it works from

  • CRM exports, deal notes or call records
  • Your qualification criteria, ICP or scoring rules

What you get back

  • A scored view of each candidate with reasons shown
  • A prioritised action list for the team

— HOW IT BEHAVES

How Win/loss interview post-mortem produces its result

The mechanics behind this specific template — what it reads, what it calculates, and where a human stays in the loop.

Every row of the candidate pool

Each row of your export is processed on the same basis, so no candidate is skipped however long the table is.

The pattern charted

Movement across the candidate pool is visualised from the computed data, so the trend is legible at a glance.

Composed as work product

Findings on the candidate pool are written up as a document that reads like professional output, with each claim tied back to a candidate.

Roll-up alongside candidate-level detail

Detail rows are summarised into the grouped view of the candidate pool without losing the underlying candidates.

Why this is expensive by hand

Reading the candidate pool usually depends on what reps put in the CRM and what a leader remembers from calls. In practice it shows up as pipeline read you can trust: assess every candidate against defined criteria rather than optimistic self-reporting. The value sits in the rigour, not the typing — yet the rigour is exactly what gets traded away when there is only 2–3 weeks of capacity for it.

How this Skill produces it

Skillsize turns that work into a Skill: you supply the material, and what comes back is a scored view of each candidate with reasons shown, with a prioritised action list for the team. The criteria, ordering and review points that make the answer trustworthy are encoded in the Skill itself — which is the difference between a structured method and a prompt someone pastes in. Net effect: 2–3 weeks down to ~40 minutes, no drift between runs, and every conclusion traceable back to the evidence behind it.

Who it's for

  • Revenue and commercial leaders
  • Sales operations and enablement teams
  • Customer success and account management leads
  • Consultants advising on go-to-market

Run it in Skillsize — or export it anywhere

Win/loss interview post-mortem exports as a structured SKILL.md file and is MCP-ready, so the same method runs in ChatGPT, Claude, Copilot or your own AI products. Adapt it to your methodology, and the intelligence stays yours — not locked to one vendor.
