ArcPM Knowledge is a structured collection of product management concepts, definitions and frameworks designed to be understood by both humans and AI.
Unlike a traditional glossary, ArcPM Knowledge connects concepts, frameworks and definitions through a shared knowledge model, making product knowledge reusable across documentation, AI and product workflows.
A Connected Product Graph is a single, linked structure that ties every product artifact — research, requirements, decisions, prototype, and PRD — into one graph, so a change in one place surfaces its impact everywhere it connects.
The ArcPM Framework is a five-stage method for turning one product idea into a testable prototype — Research, Insight, Requirement, Decision, Prototype — where every stage stays connected in a Connected Product Graph so changes propagate instead of drifting. The PRD is exported from the result, not written as a sixth document.
