This infographic shows the full four-phase evaluation funnel, narrowing from five shortlisted firms down to one signed partner, and flags exactly where bad partnerships typically originate.

Key takeaways

  • Phase 1 (Shortlist) narrows from portfolio review, case studies, LinkedIn team checks, and Glassdoor signals down to a top 5 firms.
  • Phase 2 (Interview) — technical calls, hard questions, client references, and a redflag checklist — narrows further to a top 2 firms.
  • Phase 3 (Paid Trial) — a 2-week discovery engagement assessing spec doc quality, communication pace, and how the team pushes back — selects the final 1 firm.
  • Most businesses skip Phases 2 and 3 entirely — that's where 80% of bad partnerships begin. Phase 4 (Contract) should formalize IP ownership, source code rights, exit clauses, and payment terms only after the prior phases are complete.
