A design partnership should retire a product uncertainty that matters to more than one customer.
Choose the uncertainty first
Before recruiting a design partner, write down what the company needs to learn. It might be whether a workflow saves enough time to justify switching or whether a buyer can obtain the data needed to use it. A partner is useful when its normal work exposes that uncertainty. Prestige alone is a weak reason to accept a demanding collaboration.
Agree on a bounded experiment
Specify the workflow, who will participate, what access is needed and when both sides will review the result. A hypothetical partner might commit to using a scheduling product for one team over a month and attending two feedback sessions. That is more informative than an open-ended promise to try the product whenever someone has time. Clarify commercial expectations before the relationship drifts.
A bounded design partnership
Question
State the uncertainty to resolve.
Commitment
Agree on usage, access and feedback.
Learning
Separate general needs from custom work.
Decision
Set a date for buying, extending or stopping.
Separate product work from special requests
Keep a record of requests and the problem behind each one. Some reveal a repeatable need; others reflect one organisation’s internal conventions. Ask whether another likely customer would benefit from the same change. If a request requires a unique integration or substantial service work, price and describe it separately. Otherwise the roadmap can quietly become a collection of obligations that cannot scale.

End with a real decision
At the review date, decide whether the partner will pay, continue a clearly defined experiment or stop. An indefinite pilot can create the appearance of traction without a buying decision. Capture what changed in the product and which assumptions were disproved. The strongest outcome is a repeatable proposition the next customer can understand, even if the original partner decides not to purchase.
