# Choosing UX artifacts and prototype fidelity

*Platform User Experience Designer Study Guide · UX Fundamentals · Last updated October 16, 2026 · https://www.certifyforce.com/study-guide/user-experience-designer/ux-fundamentals/choosing-ux-artifacts-and-prototype-fidelity*

Which UX artifact answers which question (journey map, service blueprint, ecosystem map, empathy map, mental model, storyboard), what a design brief and a Jobs to Be Done statement settle first, and how to pick prototype fidelity from the question you need answered.

- Certification: Salesforce Platform User Experience Designer
- Exam section: UX Fundamentals
- Study guide: https://www.certifyforce.com/study-guide/user-experience-designer

**Official exam objective:**

> Given a scenario, identify which UX method should be used to define a user experience.

## What the exam expects

- Given a scenario, pick the map-type artifact that answers it: journey map, service blueprint, ecosystem map, empathy map, mental model or storyboard.
- Settle the design brief (personas, Jobs to Be Done, constraints) with stakeholders before anyone sketches.
- Write a Jobs to Be Done statement and tell it apart from a user story, a persona description and a system requirement.
- Pick the prototype format from the question the prototype must answer (ideation, exploration, validation), and know when a screen area is ready for high fidelity.

Key terms: **UX artifact** (a craft-based deliverable of the design process; two categories, mapping and screens); **design brief** (living document holding the critical information and plan for the work); **Jobs to Be Done** (framework that defines success from the customer's perspective); **fidelity** (how closely a prototype conveys the intended experience of the final product).
