2. The VP of purchasing has complained that the POs are taking too much time to process. He would like all the POs generated in a day till 4 pm, to be completed within the day. (25 points) As a process analyst, you first decide to use six-sigma techniques to improve this process. But, given the costs, you cannot hire more resources. Cross-training is out of the question as well due to the expectation of segregation of duties. Think about at least 2 other solutions to improve this process, and list them. (Hint: Can you do some activities in parallel? Can you remove some wasteful activities or reduce time for them?) Simulate at least one such solution and take a screenshot of appropriate output from the results that shows improvement. (Note: You may not be able to achieve VP's demand with this one solution - This is fine. You would however need to show improvement in the process)
