Writing A Technical Brief That Gets You An Accurate Estimate

Begin with the problem you are solving, not a feature list. Which people will use it day to day, how software outsourcing works many times a day, and what happens today? A vendor who knows what you are trying to achieve will suggest an alternative that costs less; one who only sees a list of screens prices exactly what you asked for.



Describe the scope as short scenarios: who does what, vue js or angular and what happens next. Equally important, list what is out of scope. An explicit exclusion list removes more argument during acceptance than almost anything else in the document. Indicate as well which items are decided and which are still open — estimators price uncertainty, and pretending everything is fixed helps nobody.



Write down the hard constraints. This means existing systems the sla based software support has to talk to, the data you already hold and its condition, regulatory obligations, offshore development team for moscow expected load, target platforms and infrastructure that is already decided. If a deadline is real, say why: a good team is usually able to resequence the work to hit it, but not if the date is a secret.



Write down what completion means for the important items. Acceptance criteria need not use special syntax: a short list setting out what a user should be able to do is sufficient. That one addition shortens the review at the end by a surprising margin and removes most late-stage disagreement.



To close, say what you expect back. Request a breakdown by feature or module, the assumptions behind each number, whatever the team considers risky and a low number and a high number. Take a broad range as a signal about the brief: it normally identifies the part of the brief that needs work. At that point tighten that section and request a revised number — the second estimate will be far closer to reality.
