Open with the reason this software development lifecycle should exist, not your preferred technology. What kind of user will use this, how many times a day, and what does the process look like without it? A vendor who knows what you are trying to achieve can propose a cheaper route to it; one who only sees a feature list can only price the list as written.

Define what is included as concrete flows: a walk through each important path. Just as important, write down what the first release deliberately excludes. An explicit exclusion list prevents more disagreement at delivery time than almost anything else in the document. Mark too which decisions are settled and which are still under discussion — honest teams price those differently, and hiding it helps nobody.

List the constraints. These include systems you must integrate with, the data you have and where it lives, regulatory obligations, expected load, target platforms and stacks you cannot change. Where a date is genuinely fixed, say why: an experienced team can often cut the right scope mvp development mistakes to avoid meet it, provided they hear about it early.

Say what done means feature by feature. Testable acceptance criteria do not require special syntax: a plain-language note describing what must be true when the feature works will do. This one section shortens the review at the end by a surprising margin and closes off the usual argument at handover.

One last thing, state what you want in the response. Require a task-level breakdown, a written list of assumptions, the main risks and a range rather than a single figure. Take a broad range as a signal about the brief: it normally identifies where your description is thin. At that point tighten that section and request a revised number — the next version will be the one worth planning around.
