A team calculates takt time as 60 seconds. If the current cycle time is 75 seconds, what action is most appropriate?
Answer: Identify and eliminate waste to bring cycle time at or below 60 seconds
When cycle time exceeds takt time the process cannot meet customer demand rate, so waste must be eliminated to close the gap.
Which element is NOT typically included in a Standard Work document?
Answer: Employee performance ratings
Standard Work documents capture takt time, work sequence, standard WIP, and quality checkpoints—not individual employee performance evaluations.
In a fishbone (Ishikawa) diagram, the 'head' of the fish represents:
Answer: The problem or effect being analyzed
The head of the fishbone diagram contains the clearly stated problem or effect, while the bones represent potential cause categories.
Which of the following best describes the purpose of a supermarket in Lean production?
Answer: A controlled buffer of standard inventory that is replenished only when withdrawn by downstream processes
A Lean supermarket is a regulated inventory point with defined quantities; when downstream pulls items, a signal is sent upstream to replenish only what was consumed.
What is the main benefit of converting internal setup steps to external setup steps in SMED?
Answer: It allows setup activities to be performed while the machine is still running, reducing downtime
External setup tasks can be prepared before the machine stops, so actual machine downtime during changeover is significantly reduced.
A process engineer wants to quantify how frequently a specific defect type occurs compared to all defects. Which tool provides this analysis most effectively?
Answer: Pareto chart
A Pareto chart ranks defect types by frequency, making it easy to identify which few categories account for the majority of problems (the 80/20 rule).
In Lean, what does 'genchi genbutsu' (go and see) emphasize?
Answer: Going to the actual place where work is done to observe and understand the real situation
Genchi genbutsu means going to the actual workplace (gemba) to observe firsthand rather than relying solely on data or secondhand accounts.
