SaaS Applications

What software do you need, should you build or buy it, and how far along are we?

One table. Five answers per row. Stop here before going deeper.

Capability Router

Essential = needed before day one. Primary = needed within first quarter. Secondary = test when ready. Defer = skip until demand pulls.

Verdict logic: Build what touches your data model. Buy commodity. Bridge everything else. ROI methodology: Priority = (Current + Fit + Value + Edge) / 4 × Edge.

Questions

Which software categories generate data that becomes your competitive advantage — and which are commodity pipes?

  • If CRM is 75% built but Blockchain is 0%, yet Blockchain scores higher on ROI — what does that tell you about sequencing vs scoring?
  • What happens to your business if any "Reserve" vendor shuts down tomorrow — and does the verdict column reflect that risk?
  • When a category says "Buy + Bridge", what's the trigger that converts bridge to build?
  • Which "Defer" category would jump to "Primary" fastest if a venture activates its vertical?
