How to run an Agentforce Service engagement: choose waterfall, agile or a paid discovery phase from how settled the requirements are, discover the real process by observing reps, prioritize needs against budget, control scope creep with change requests, and prove value against a baseline after go-live.

- Certification: Salesforce Agentforce Service Consultant
- Exam section: Implementation Strategies

**Official exam objective:**

> Given a scenario, determine how to participate in a successful consulting engagement.

## What the exam expects

- Choose waterfall, agile or a paid discovery phase from how well defined the requirements, scope, budget and feedback needs are.
- Pick the discovery technique that reveals how reps really work, and find the root need behind a stated requirement.
- Prioritize a requirement list against a fixed budget and make the out-of-scope boundary explicit.
- Handle scope creep with change control and re-baselining; resolve conflicting requirements between business units.
- Show business value after go-live against the discovery baseline.

Key terms: **scope** (all the work needed to deliver the outcome, including what is not included); **scope creep** (unauthorized changes included without approval); **triple constraint** (scope, schedule and cost); **elicitation** (drawing information out of stakeholders); **RACI** (responsible, accountable, consulted, informed).
