CPS Process Measurement & Metrics 2

Question 1

Takt time in process measurement is calculated as:

Accepted Answer

Available production time divided by customer demand rate

Answer

Takt time = Available production time / Customer demand, setting the pace at which a process must operate to meet demand without overproducing.

Question 2

The process capability index Cp measures:

Accepted Answer

The ratio of the specification width to the natural process variation (6σ)

Answer

Cp = (USL − LSL) / 6σ, comparing the width of customer specifications to the spread of natural process variation to assess potential capability.

Question 3

First Pass Yield (FPY) is defined as the percentage of:

Accepted Answer

Units that complete a process correctly without any rework or repair on the first attempt

Answer

FPY measures the proportion of units that pass through the entire process correctly the first time, with no rework, scrap, or repair needed.

Question 4

In Statistical Process Control (SPC), control limits are set at:

Accepted Answer

±3 standard deviations from the process mean

Answer

Control limits are placed at ±3σ from the process mean, representing the range of natural process variation; points outside indicate special-cause variation.

Question 5

Mean Time Between Failures (MTBF) is a metric used to measure:

Accepted Answer

The average operating time between consecutive failures of a process or system

Answer

MTBF quantifies the average duration of successful operation between failures, serving as a reliability indicator for equipment and processes.
