your operations are potentially constrained by things like employees, queuing space, parking spots, square footage in a physical location, bandwidth for electronic processing, inventory storage space, order fulfillment space, etc. Using a simple Excel spreadsheet of your construction, make a good faith effort to quantify some of these constrains, as relevant to the organization you have in mind. How would you begin to mitigate some of these constraints how would that change your capacity model? For example, adding another shift of employees, adding another facility, increasing your square footage, etc.
