It might help to follow these steps.

$1.$ List the resources. These are the people or machines$/$equipment that make the product or serve the customers. Examples include the cashier and espresso maker, etc. at Starbucks. Also, the teams that create the file or contact former employers at the Resume Evaluation company in the class example.

$2.$ Find the capacity of each resource. Sometimes it is useful to express the capacity as a rate $($such as units per hour, or customers per day$)$ that the resource can handle. Most of the time, however, it is best to express this as time available $($such as minutes per hour, or hours per day$).$ Choose the time units so that you are consistent throughout the problem. For HW #$2,$ it is best to think about capacity in terms of hours available per day. So$,$ use the number of workers at each category $($programmers$,$ etc.$),$ and the hours per day that they work. This gives you the hours available per day for the team. You don't need to worry about whether a day is $24$ hours $-$ just think how many hours the team has available in a day. Say, for example, that programmers each work $10$ hours per day. If you had $2$ programmers, the programming team would have $20$ hours available capacity in a day.

$3.$ List the tasks that need to be done to meet demand. In the Starbucks example, a task is pouring drip coffee. Another task is making espresso drinks, and so on$.$

$4.$ Find the requirement on each resource to meet the demand. Be sure to match time units with the resource capacity. If you express resource capacity as minutes per hour, you should express the requirements in minutes per hour. In HW #$2,$ you need to capture the number of customers that require each type of job, and the hours that the team works on that job. So$,$ for instance, if there are $3$ customer requests for Basic Update per day, how many hours does the programming team work on those jobs? Repeat that for all types of jobs and all resources, and then get the total number of hours per day that each resource team works per day in order to meet demand.

$5.$ Calculate the implied utilization of each resource $=$ demand required of the resource $/$ available capacity of the resource.

$6.$ Answer the relevant questions $$ supply or demand constrained, bottleneck, etc.
