Comparion® by Expert Choice is an enterprise-grade decision-making platform built around the Analytic Hierarchy Process. It enables organizations to structure decision problems clearly by defining objectives, sub-objectives and alternatives, and to measure the importance of competing objectives. Teams can synthesize both quantitative data and expert judgments, explore trade-offs through what-if and sensitivity analyses, and optimize scenarios for resource allocation. The platform supports collaborative decision making: multiple participants can contribute; there are tools for group consensus and alignment. Use-cases include strategic planning, project & product management, capital budgeting, vendor or source management, trade studies, marketing strategy, and human resources. Comparion also provides dashboards, reports, and portfolio analysis, helping users communicate outcomes clearly and adapt to changing priorities. It’s designed to reduce risk in decision-making and increase alignment across teams.
