Situation in production
The customer wants to see the requirement was met
A complaint or an audit. Can you show what was made and how it was inspected?
What happens
A customer files a complaint, or a customer or auditor asks to see how a particular order was inspected.
What should apply
It should be possible to show what was made, how it was inspected, by whom, and what was done when something deviated.
Why it is difficult
- The information exists, but in different systems, binders and emails.
- Compiling an answer takes time and ties up key people.
- What was not recorded when it happened cannot be recreated afterwards.
The context that is needed
- Order and part
- Measured values and inspection results
- Operator and time
- Deviations and actions
- Gauge and calibration status
Why do annotations make a measured value more useful?
Illustration · Example dataA value without context can only be compared with its limit. With operator, serial number, order, machine and cavity it can be filtered, compared and traced.
Step by step
- The value 12.51 is linked to operator, serial number, order, machine and cavity.
- The cavity number makes it possible to compare cavities with each other.
- Serial number and order make it possible to trace a single part and answer the customer.
What does an inspection report contain, and what can it show?
Illustration · Example dataA report is only as good as what was recorded while the order ran. What was not saved with the value, such as order, gauge or a note, cannot be added afterwards.
Step by step
- During the order, measured values per characteristic, order, part and time, who measured and with which gauge, and notes on deviations are recorded.
- The report per order is identified by customer, part, order and date, and shows per characteristic the nominal value, lower and upper tolerance limit, count, min, max and Cpk.
- In the example the width has Cpk 1.12, below the customer's requirement of 1.33, even though every part is within tolerance.
- The report answers the customer's question of whether the requirements were met, the auditor's question of how and by whom it was inspected, and quality's question of what to act on first.
Same situation, different questions
Who needs to know what
The same event looks different depending on which decision you have to make.
The same evidence for everyone
- Order and part
- Measured values and inspection results
- Operator and time
- Deviations and actions
- Gauge and calibration status
