問題文
A wholesale distributor is replacing a spreadsheet-based commission process. The finance team cannot describe the commission rules in writing; they say they will know what they want once they see numbers on a screen. The budget is fixed but the scope is open. Which development methodology best fits, and why?
選択肢
- An iterative approach, because it removes the need for a formal acceptance step at the end of the project.
- An iterative approach, because each increment produces working functionality that finance can react to, and the next increment is planned with what they learned.
- A sequential approach, because the budget is fixed.
- A sequential approach that starts with a signed requirements document covering every commission rule, because a fixed budget can only be protected by freezing the scope before any configuration begins, and because a signed document is what makes the delivery team accountable for the outcome.
