Product Logic & Iteration Loop Worksheet

Use when you need to answer: "Can we state, in one sentence, who this is for, what we're building, and why?"

Compress the full chain of reasoning into one sentence a stakeholder can understand in seconds.

Core Question

  1. Can we state, in one sentence, who this is for, what we're building, and why?

What to Document

  1. Product logic sentence: 'For [core customer], this [minimum output] will address [priority problem] and help achieve [desired outcome], measured by [evidence].'

  2. The Learn → Decide → Change → Retest loop as it applies to this product

Common Mistake to Avoid

  1. Letting the product logic drift into vague language ('improve the experience') that no longer names a customer, a problem, or a measurable outcome.

Illustrative Example

  1. 'For busy account managers, this automated follow-up suggestion list will address missed commitments and help achieve on-time follow-up, measured by 24-hour completion rate.'

Output of this stage

A stakeholder outside the team can repeat the logic sentence accuratelyThe sentence names a customer, a problem, an output, and a measurable outcome
