Function Models
Flat, ontological maps of what a function actually consists of — inputs, activities, capabilities, tools, and outputs. Unlike the maturity models, a Function Model doesn’t measure AI-nativity or progression; it names what the function is, independent of how well any organization currently does it.
Product Management Function Model
How market, user, and business inputs become the activities, capabilities, and tools of the PM function — and what it hands off to engineering, GTM, operations, and leadership.
Product Marketing Function Model
A bounded corollary to Product Management — how market and buyer context becomes messaging, launch assets, and field enablement, and what it hands back to the rest of the business.
Software Engineering Function Model
How approved requirements become reliable, secure, maintainable software in production — and what it hands back to product, GTM, operations, and leadership.
Each Function Model shares this same Inputs / Function / Outputs structure — more are planned.
