Deterministic scores · rules-based, not AI iHow these scores are obtained: each one is computed from this profile's listed attributes — capability checkboxes, certifications, capacity figures and coverage — by a fixed formula, recomputed on every page load. Deterministic and rules-based means the score comes from a fixed, transparent formula over listed attributes — the same inputs always produce the same score. It is not AI: there is no model, no learning, and no hidden weighting. Whether a score is relevant to you depends on your specific project: a capability that raises the number may not matter for your work, and a niche strength your project needs may barely move it. Capability scores are a directional starting point, not a verdict. A lower score does not disqualify a company or consultant, and no decision should rest on the score alone — always contact the company directly to confirm the specifics for your project.
