Start with the business problem, not your preferred [[https://webparadox.com/how-we-work/consulting/|technology consulting company]]. What kind of user will use it day to day, with what frequency, and what does the process look like without it? An experienced team who knows what you are trying to achieve often proposes a simpler way to reach it; a team that receives only a feature list will price the list as written.



Set out the scope as short scenarios: what the user does and what the system does in response. Equally important, write down what you are not building. A written out-of-scope list removes more disagreement at delivery time than any other single page. Mark too which parts are firm and which are still under discussion — estimators price uncertainty, and concealing the open questions only hurts you.



Write down the hard constraints. These include the platforms and [[https://webparadox.com/how-we-work/support/|legacy code maintenance services]] involved, the data you already hold and its condition, security and compliance rules,  [[https://webparadox.com/locations/dubai/|custom software development dubai]] expected load,  [[https://webparadox.com/hire/vuejs-developers/|vuejs agency]] which devices matter and stacks you cannot change. If a deadline is real, explain what drives it: a team is usually able to cut the right scope to meet it, but not if the date is a secret.



Define what done means for the important items. Acceptance criteria do not require special syntax: a short list describing what must be true when the feature works is sufficient. This single habit shortens acceptance testing dramatically and closes off most late-stage disagreement.



To close, ask for a specific format. Require an itemised estimate, the assumptions behind each number, the main risks and a low number and a high number. Read a wide range as a signal about the brief: it usually points to the part of the brief that needs work. At that point clarify that area and request a revised number — the revised figure tends to be much more reliable.
