The Decision Design Equation

Creator: Alexander Dinola Date of first use / creation: October 2025 Description: The Decision Equation for Complex B2B Sales is a diagnostic framework stating that complex deals move only when the perceived cost of staying the same (Status Quo Tax) becomes heavier than the perceived cost of changing (Switching-Loss Perception), and the path forward feels credible enough to defend (Certainty). It further requires Portability of the internal case and measurable Decision Weight (buyer-owned effort). It is not a mathematical formula but a structured lens for inspecting why a seemingly rational recommendation remains difficult for a buying group to own and defend after the seller leaves.
