HKSM

A preliminary, functional model created to gather early stakeholder feedback on the envisioned product before full-scale development.

Key Points

• Built early to test assumptions, workflows, and usability with stakeholders.
• May range from low- to high-fidelity depending on the questions to answer.
• Clarifies requirements and aligns expectations, reducing risk and rework.
• Supports iterative development by informing backlog items and design choices.

Example

On a new e-commerce project, the team builds a basic checkout flow with a mock payment service. Users try the flow, provide feedback on steps and messages, and the team updates user stories and designs before implementing the full payment integration.
