For my project, I ran Coffee-Roma, a coffee shop located in the business district of a large city. My simulation ran for 60 days. Over this timeframe, I hired 7 employees and earned gross revenues of $89,984.20. From those revenues, my net profit totaled $14,046.83. Below are the details of how I attempted to best run my business.

What adjustments did you make to try and improve performance?

Pertaining to any adjustments related to cost savings, was it changes to variable costs, fixed costs, or both? Give specifics.

With respect to supplier discounts, those adjustments were related to variable cost savings. Generally, those variable cost savings would be best described as savings related to cost of goods sold.

My inventory control procedures produced both variable and fixed cost savings.

Put simply, the less inventory I lost to waste, the more variable cost savings I experienced. In addition, I experienced shipping cost savings. Shipping costs were themselves mixed costs, involving both fixed and variable components. By using the longer shipping windows, I was able to reduce the fixed component of the shipping cost. For example, my main supplier offered five-day
