Capacity and Bottlenecks

Operations turn promises into actual delivery. Map the steps, inputs, and handoffs so problems can be measured and improved.

Process and Capacity

Objective: Explain process and capacity, distinguish their meanings, and apply them to a described case.

Process: A process is a sequence of activities producing an outcome. Capacity: Capacity is the output achievable under specified resources and conditions. Operations translate a promise to customers into a repeatable process. A local improvement does not necessarily improve the entire system if another required step remains the bottleneck. Inventory and supplier decisions involve trade-offs among service, cost, reliability, and cash. Quality includes meeting appropriate expectations and learning from failures. Track evidence across the process rather than relying only on a final outcome. Application: An order moves through booking, preparation, and delivery. This most directly illustrates process. A workshop can complete a stated number of jobs daily. This most directly illustrates capacity.

Worked examples

Try itOriginal teaching scenario: An order moves through booking, preparation, and delivery. Which idea from this section does it most directly illustrate?Show answer

Step 1 — Read the observation: An order moves through booking, preparation, and delivery. Step 2 — Recall the relevant idea: A process is a sequence of activities producing an outcome. Step 3 — Connect the observation to the idea: The scenario is an illustration of process. Step 4 — Check the limit: This short scenario illustrates the concept; it does not establish every detail or exclude every other influence in a real situation.

Bottleneck and Lead time

Objective: Explain bottleneck and lead time, distinguish their meanings, and apply them to a described case.

Bottleneck: A bottleneck constrains the rate of an overall process. Lead time: Lead time is elapsed time from a defined request to fulfillment. Operations translate a promise to customers into a repeatable process. A local improvement does not necessarily improve the entire system if another required step remains the bottleneck. Inventory and supplier decisions involve trade-offs among service, cost, reliability, and cash. Quality includes meeting appropriate expectations and learning from failures. Track evidence across the process rather than relying only on a final outcome. Application: One slow station limits completed orders. This most directly illustrates bottleneck. A customer waits from order placement to receipt. This most directly illustrates lead time.

Step 1 — Read the observation: One slow station limits completed orders. Step 2 — Recall the relevant idea: A bottleneck constrains the rate of an overall process. Step 3 — Connect the observation to the idea: The scenario is an illustration of bottleneck. Step 4 — Check the limit: This short scenario illustrates the concept; it does not establish every detail or exclude every other influence in a real situation.

Try itThree consecutive stations can process 22, 11, and 30 units per hour. Assume a steady flow, one required pass at each station, and no other limits. What is the maximum overall hourly rate?Show answer

Step 1 — Identify the quantities and assumptions in the prompt. Step 2 — Select the relationship: Simplified serial-process rate = minimum required station capacity. Step 3 — Calculate: min(22, 11, 30) = 11. Step 4 — Report with units: 11 units per hour. This result applies to the stated example, under the assumptions specified in the question.

Workflow and Standard procedure

Objective: Explain workflow and standard procedure, distinguish their meanings, and apply them to a described case.

Workflow: A workflow organizes steps, responsibilities, and information movement. Standard procedure: A standard procedure documents a repeatable method while allowing appropriate exceptions. Operations translate a promise to customers into a repeatable process. A local improvement does not necessarily improve the entire system if another required step remains the bottleneck. Inventory and supplier decisions involve trade-offs among service, cost, reliability, and cash. Quality includes meeting appropriate expectations and learning from failures. Track evidence across the process rather than relying only on a final outcome. Application: A team assigns a clear handoff between preparation and dispatch. This most directly illustrates workflow. Workers follow a defined quality-check sequence. This most directly illustrates standard procedure.
