The Scope Creep in a Family Business

Each request has a different answer, and treating them as one 'yes' or 'no' would be a mistake.

1. Supplier dispute - Outside scope (commercial/legal, not the sibling-communication assessment). Decline, but offer a warm handoff to a commercial attorney or procurement advisor. Sitting in 'informally' would create ambiguity about my role and could expose me to liability if the dispute escalates.
2. PIP for the plant manager - Outside my competence and jurisdiction-specific; employment actions carry legal risk. Decline and refer to an employment lawyer or qualified HR professional. Offering to help the manager's communication with the plant manager, within the assessment frame, is a possible narrow carve-out.
3. Advising on removing the CFO - This is the serious one. It's (a) outside scope, (b) a governance/legal decision, and (c) requested without the sister's knowledge, which makes me a covert party to a power move against a co-owner. I would decline clearly: 'I can't advise on removing a co-owner, and I won't do it without her knowing the question is on the table. If you want to explore the sibling role structure, that's a conversation we have with her present.'

The through-line: 'it's all related' is exactly the reasoning that turns a bounded assessment into an uninsurable, unethical entanglement.

In the moment - calm, non-judgmental, firm:

• Acknowledge the pressure: 'I hear that it all feels connected, and some of it is.'
• Draw the line by competence and consent, not by fee: 'The supplier and PIP work need legal/HR expertise I don't have. And the question about your sister's role - I can't take that on without her in the room. Advising one co-owner about the other behind her back would damage the very relationship I was hired to fix.'
• Offer what I can do: 'If you want to discuss the sibling role structure, let's put it on the agenda for a joint session. That's within scope and it's the honest version of the question.'

In writing (same day, brief email):

• Confirm the original scope and fee remain unchanged.
• Note the three requests, my response to each, and the referrals offered.
• State the consent principle for the CFO question.
• Invite him to confirm or raise concerns.

Documentation protects the client relationship, clarifies expectations, and creates a record if the sister later learns of the request.

I'd stay warm and non-defensive, and separate the threat from the substance:

• 'You're free to bring in whoever you need for the supplier and the PIP - I'd encourage it, because those need specialists. My concern isn't turf; it's that I'm not the right person and pretending otherwise would hurt you.'
• On the sister: 'If you find someone willing to advise on removing a co-owner without her knowledge, I'd ask you to think about what that does to the business and the family. I'm not the only person who would flag that.'
• Reaffirm value: 'The work we're doing on how you two communicate and decide is the thing most likely to change your outcomes. I'd like to finish it.'

I would not trade the ethical line for the fee. If he terminates the engagement over this, I'd exit professionally: deliver what's complete, invoice proportionately per the contract, and offer a clean handoff. Losing a client for refusing to be a covert instrument against a co-owner is an acceptable outcome - and the referral risk of being known as a consultant who does that is worse than the lost fee.
