In hours and outcomes, not in technology. Before we start, we agree on what the current state costs you. Usually that's time: hours per week spent on the task, or backlog depth, or response time to a customer. After the system is live, we measure the same thing again. A successful project moves the number meaningfully and the system keeps working without constant intervention. If the AI is impressive but you still spend the same hours on the task, the project failed. We'd rather build something modest that you actually use than something ambitious that needs babysitting.
