You are employed as a TAE on a project to build a purchasing system. The main requirements for the system are:

1) Allow users to enter details of items that they wish to have purchased and, from these details, create a purchase request.

2) Take each purchase request through a workflow that will allow the requestor's line manager to approve the request, reject it, or return it for clarification/modification.

3) Forward approved requests to the Purchasing Department.

4) Allow purchasers to find the best available supplier and place the request on that supplier as a purchase order.

Requirement 1 has now been delivered and has been satisfactorily tested manually. In parallel, you have developed a TAS so that functional suitability testing can be automated.

You intended to use the implementation of Requirement 1 as a pilot for the TAS. Which TWO of these objectives are MOST appropriate for this pilot?

a) Generate prototypes for the implementation options of the TAS

b) Demonstrate the suitability of at least one TAS implementation option

c) Expose any risks to further deployment of this TAS

d) Assess the quality of the implementation of Requirement 1

e) Enable a calculation of the likely return on investment for this TAS
