The Project Charter Business Case statement should define the project scope, specify improvement and business impact, detail the measurement system, and outline the resources required.
Step-by-step explanation:
The Project Charter Business Case statement "Process throughput time must be reduced in order to meet customer requirements" should include the scope of the project, defining what is included and what is not.
It is crucial to specify the amount of improvement that is required and explain the business impact that this improvement will have.
Moreover, the statement should detail the measurement system that will be employed to assess the efficiency of the process changes.
Lastly, an outline of the resources required to achieve the desired outcomes should be provided, including personnel, technology, and budget considerations.
