Question

Process view of DPS: Consider the case of DPS, where applicants interested in renewing a driving license need to perform a set of tasks. We take a process view of the DPS. The list of tasks are listed below 1. An applicant starts by filling out the application in the waiting lounge, which takes 5 minutes. The applicant proceeds to a counter where Alex, an employee at DPS, receives the application and reviews it. This task takes 1 minute. The applicant then proceeds to Bob's desk, where he checks the applicant's driving record for4 minutes Subsequently, Chloe, an employee, tests the applicants on traffic rules. This task takes 3 2. 3. 4. minutes 5. Applicants then move indifferently to Dorothy or Elsa's desk, where they get their eye test which takes 3 minutes, and their photograph taken which takes 2 minutes. 6. Then, applicants pay their renewal fee to Fiona by cash or credit card, which takes 2 minutes. 7 Finally, George verifies and issues the license, which takes 4 minutes The table summarizes the sequence of tasks above.

Explanation / Answer

The flow rate is the total time taken between raising a request by customer to the delivery to the customer.

Hence from the question, the flow time is (5+1+4+3+3+2+2+4)=24 minutes.

The cycle time is the total processing time after receiving any request. In this question if will be equal to the time taken from Alex's desk to George's desk

Thus cycle time=(1+4+3+3+2+2+4) =19 minutes.

Capacity of each resource is defined as the total throughput of that resource which is equivalent to total units processed per hour.

Alex takes 1 minute to process one applicant this is capacity will be equal to 60/(cycle time of that resource)

Thus Capacity (alex) =60/1=60

Similarly we can find capacity of all other resources.

Thus capacity(bob) =60/4=15

Capacity(chloe) =60/3=20

Capacity(Dorothy +elina) =60/5=12

Capacity (foina) =60/2=30

Capacity (George) =60/4=15

The bottleneck resource is the one that takes maximum time in the entire series process. If we consider the customer also as a part of process, then the customer is himself a bottleneck as s/he takes 5 minutes(maximum) time to file forum

However, in the process excluding the customer, Bob and George are bottleneck as they take maximum time to process (4 minutes).
