What does a diamond represent in a flowchart?
Work in process (WIP) measures units currently inside a process, whereas throughput measures completed units per unit of time.
- A
True
- B
False
The number of completed units per unit of time is called .
Expand the acronym SIPOC by listing its five elements in order, separated by commas.
A team wants to test a process change using PDCA. Select all statements that correctly describe parts of the method.
- A
During Plan, define the problem and establish a baseline.
- B
During Do, permanently standardize the change before measuring it.
- C
During Check, compare results with the baseline and look for unintended effects.
- D
During Act, skip further measurement if the initial test appears successful.
A value stream map can show material and information flow across connected process steps, helping identify opportunities to reduce waste and waiting.
- A
True
- B
False
In a sequential process with sufficient demand, the step with the lowest effective capacity is the and limits maximum system throughput.
A service team sees a long queue and wants to improve its process without assuming that the most visible delay is the root cause. Describe a sound approach to investigate and test an improvement, including how the team should use a process map, measured data, and PDCA. Explain why monitoring should continue after a change is adopted.
In a flowchart, which symbol commonly represents a decision?
- A
Rectangles
- B
Diamonds
- C
Arrows
- D
Start/end symbols
A useful process map should represent how work actually happens, even when that differs from the written procedure.
- A
True
- B
False
What flow measure counts the units currently inside a process?
Before drawing a detailed flowchart, a team wants a high-level view of suppliers, inputs, the process, outputs, and customers. Which tool best serves that purpose?
- A
A flowchart that records only step times and queues
- B
A map focused on material and information flow across connected steps
- C
A high-level map of suppliers, inputs, process, outputs, and customers
- D
A list of process participants arranged by job title
What map extends the view across connected process steps to show material and information flow and identify opportunities to reduce waste and waiting?
A team has tested a process change and is comparing the results with its baseline while checking for unintended effects. Which PDCA phase is it carrying out?
- A
Plan
- B
Check
- C
Do
- D
Act
A manager sees a long queue at one step and wants to reduce lead time. Which approach best helps avoid treating a visible symptom as the root cause?
- A
Immediately add staff to the step with the longest visible queue
- B
Remove the step that appears to take the longest, without further investigation
- C
Use the process map and measured data to investigate causes before selecting a change
- D
Increase the speed of every step by the same amount
A proposed change shortens processing time but causes more errors and worsens the customer experience. How should the team judge this change?
- A
It is successful whenever throughput rises
- B
It is successful if the change is standardized quickly
- C
It is successful as long as the bottleneck step becomes faster
- D
It is not a sound improvement if it harms quality, safety, or customer experience
A step has 6 hours of available work time per shift and takes 5 minutes per unit. Assuming all available time can be used for this work, what is its capacity? Use 1 hour = 60 minutes.
- A
12 units per shift
- B
60 units per shift
- C
72 units per shift
- D
180 units per shift
A clinic can register 12 patients per hour, examine 8 per hour, and check out 15 per hour. If demand is sufficient and these capacities remain effective, which step limits the maximum sustainable throughput?
- A
Registration, because it occurs first
- B
Examination, because it has the lowest capacity
- C
Checkout, because it occurs last
- D
No step; the three capacities combine into a higher system capacity
A team is preparing a process map of a customer-return workflow before proposing changes. Which actions would make the map more reliable and useful? Select all that apply.
- A
Define the start and end points of the process before mapping its steps.
- B
Copy the written procedure exactly and use it instead of checking how the process operates.
- C
Include decisions, rework loops, and waiting in the map.
- D
Walk through the process with the people involved and correct gaps.
- E
Add step times, queues, or errors where those measures would be useful.
- F
Remove waiting from the map so it shows only activities that add value.
