You are employed as a consultant for the Students’ Union Shop and should
• Report on their current business, pointing out any existing problems;
• Suggest improvements to their current strategies;
• Provide them with an efficient tool for easily evaluating their current performance using the data provided or new data in a similar format.

You are required to produce a model using Excel, which could be used by the Students’ Union Shop management team for evaluation of their performance using the data provided or any new data that becomes available in a similar format.

The model should be supported by technical documentation, which should give details of the analysis method used, include a description of how it was implemented in a spreadsheet and a brief description of how to use the spreadsheet.

You are also required to produce a main report which should review the current situation of the Students’ Union Shop queuing system and suggest ways of improving the service level. You must give a convincing argument to support the improvements you are suggesting, e.g. by showing the cost-benefit of adding an extra cashier in terms of staff utilization and customer waiting time.
