- Score proposals on: capability fit, measurable KPIs, implementation resource model (embedded vs. advisory), and tech integration (HRIS/LMS).
- If you want, I’ll convert this into a vendor shortlisting matrix (side-by-side: best fit use case, strengths, pricing model estimate, recommended pilot scope). Which format would you prefer? PDF brief, one-page comparison table, or an RFP template?
