Writing a Technical Brief That Earns a Reliable Estimate > 자유게시판

Start with the problem you are solving, not a list of screens. What kind of user will use the system, with what frequency, .net core cross-platform development workload and how is the job done today? An estimator who knows what you are trying to achieve can propose an alternative that costs less; one who only sees the requirements as given can only price your assumptions along with the work.

Define what is included as user stories or scenarios: who does what, and what happens next. Equally important, state explicitly what you are not building. An explicit list of exclusions saves more disagreement at delivery time than the rest of the brief combined. Mark too which items are decided and which are still open — estimators price uncertainty, and pretending everything is fixed helps no one.

List the constraints. The list covers systems you must integrate with, the data you have and where it lives, regulatory obligations, user volumes, software developer hourly rate supported browsers or devices and infrastructure that is already decided. If a deadline is real, explain what drives it: a team can often rearrange the plan to protect it, but not if the date is a secret.

Say what done means for the important items. Clear acceptance criteria do not need special syntax: a plain-language note stating what must be true when the feature works will do. That one addition shortens acceptance testing by a surprising margin and eliminates the usual argument at handover.

One last thing, say what you expect back. Ask for a breakdown by feature or module, a written list of assumptions, whatever the in house team vs outsourcing costs considers risky and an optimistic and a pessimistic figure. Read a wide range as useful information rather than evasion: it outsourcing development normally identifies where your description is thin. Then clarify that area and ask for a new estimate — the revised figure will be far closer to reality.
