You are employed as a TAE on a project to build a purchasing system. The main requirements for the system are to: 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 have just conducted a pilot of the TAS on the implementation of Requirement 1 and several things went wrong: One test failed because some reference data that it needed was missing, this and several other failures were difficult to diagnose. Another test failed unexpectedly because an old version of the script was used. Which THREE measures could mitigate these risks during deployment?
