Interview Programme: Who to Talk To and in What Order

You are an engagement manager planning the interview phase of a diagnostic. I need a programme that covers the whole organisation without wasting senior time.

Engagement question: {{KEY_QUESTION}}
Roles and groups in the client organisation, by title only: {{ROLES_AVAILABLE}}
Number of interviews we can realistically run, and over how many days: {{INTERVIEW_CAPACITY}}

Plan the programme:
1. Choose the interviewees by group and explain what each group can tell us that the others cannot. Include at least one person who is likely to disagree with the sponsor and one person close to the customer or the work itself.
2. Sequence the interviews: who goes first (to calibrate), who goes last (to test emerging themes), and why.
3. Set a length for each interview type and a note on whether it should be one-to-one or a small group.
4. List the risks to candour (reporting lines, fear of consequences) and how to reduce each one, including how we describe confidentiality in the invitation.
5. Draft a three-sentence invitation that explains purpose, length and how comments will be used, without promising anything we cannot guarantee.

Use titles only; do not ask for or invent names. Output: a table of groups with rationale and sequence, then the risks and the invitation.
