To measure micrometre reading, use a micrometre screw gauge and take the reading from the scale and thimble.

• Clean the micrometre screw gauge before use

• Place the object to be measured between the anvil and spindle

• Turn the thimble until the object is firmly held

• Read the scale and thimble to get the micrometre reading

• Take multiple readings and calculate the average for accuracy

• Also known as Ishikawa diagram or cause-and-effect diagram

• Used in quality control to identify root causes of defects

• Categories include people, process, equipment, materials, environment, and management

• Example: A fishbone diagram can be used to identify the possible causes of delays in a manufacturing process
