modeling

The practice of producing simplified representations of a system, solution, or deliverable (e.g., prototypes, diagrams, or storyboards) to explore, validate, and communicate ideas.

Key Points

  • Captures the essentials of a product or process without full detail.
  • Common forms include prototypes, diagrams, wireframes, and storyboards.
  • Supports early feedback, shared understanding, and assumption validation.
  • Iterative and refined as new learning and stakeholder input emerge.

Example

On an agile mobile app project, the team builds low-fidelity wireframes and a clickable prototype to review user journeys with stakeholders in Sprint 1, then updates the models based on feedback before starting development.

PMP Example Question

  1. Earned value analysis
  2. Modeling
  3. Variance analysis
  4. Monte Carlo simulation

Correct Answer: B — Modeling

Explanation: Modeling uses simplified artifacts such as prototypes, diagrams, or storyboards to visualize and validate the solution before development.
