**Purpose.** Requirements are what separate an intelligence function from a news-reading service. This module walks through the intelligence lifecycle phase by phase and teaches you to elicit stakeholder needs, write priority intelligence requirements (PIRs) and supporting intelligence requirements, plan collection against them, and close the loop with dissemination and feedback.

**Prerequisites.** Module 1 of this path (CTI definition, consumers, intelligence levels, products and TLP).

**Measurable outcomes.** After this module you can:
- Name the six lifecycle phases in order and describe the analyst's work in each.
- Run a structured stakeholder interview and separate intelligence needs from requests that belong to other functions.
- Write PIRs and intelligence requirements that are tied to a decision, specific, answerable, time-bound and prioritised.
- Build a simple collection plan that maps each requirement to sources and an owner.
- Design feedback questions and outcome measures for an intelligence product.

**Practical completion objective.** In the lab you read a synthetic stakeholder interview transcript from a fictional manufacturer, sort its statements, and write a PIR set with supporting intelligence requirements.
