Gartner: B2B buyers complete "six buying jobs" in non-linear "looping" order

Claim: Per Gartner's B2B buying journey research, B2B buyers complete six buying jobs in non-linear / "looping" order — not a sequential funnel:

  1. Problem identification
  2. Solution exploration
  3. Requirements building
  4. Supplier selection
  5. Validation
  6. Consensus creation

Confidence: Verified (Gartner primary).

Implication for IA: A linear funnel-shaped site (Home → Services → Pricing → Contact) assumes a sequence buyers don't follow. The IA should support mid-funnel re-entry from any page — e.g., a buyer in the "validation" job lands on a case study, then jumps back to "solution exploration" on a vertical page. Cross-links between vertical pages, case studies, and services pages enable the loop. See Gartner: real B2B buying journey looks "like a big bowl of spaghetti" (pull quote) for the canonical metaphor and Gartner: typical B2B buying group is 6-10 decision-makers; ~95% revisit earlier decisions (CSO Update, 2019) for the group-size finding.
