Situations in production
The same event looks different to the operator, quality, production and management. Here we describe common situations: what happens, what should apply, and which questions need answers.
8 situations
Choose the one that resembles your everyday work
Each situation describes the course of events, what should apply, which decisions need to be made and which solutions and concepts belong to it.
Situation
Values creep towards the limit
Every part passes, but the measured values drift in one direction as the tool wears.
Read about the situationSituation
A part measures outside tolerance
At inspection a value lands outside the limit. Is it the part, the process or the measurement?
Read about the situationSituation
Two operators, same part, different values
The same part gives different results depending on who measures or with what.
Read about the situationSituation
The machine is down
A machine stops. How often, for how long and why, and do you find out in time?
Read about the situationSituation
Changeover to the next part
Tools, programs and settings are changed. When is the first part approved?
Read about the situationSituation
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?
Read about the situationSituation
Incoming material does not meet requirements
A batch deviates at incoming inspection, or causes problems only in production.
Read about the situationSituation
Quality work rests on a local system and a few key people
It works today. But what happens when the business grows or someone leaves?

Roles and situations
Who needs answers in which situation?
A situation rarely affects just one role. The table shows which roles have their own question in each situation. Choose a row for the situation or a column for the role.
| Situation | Operator | Quality | Production | Engineering and planning | IT | Management |
|---|---|---|---|---|---|---|
| Values creep towards the limit | Operator: Does the part pass, and should I adjust now? | Quality: Is the process still stable and capable? | Production: Will this lead to a stop or scrap if nobody acts? | Engineering and planning: Why is the tool behaving differently, and should the change interval be adjusted? | No question of its own | Management: Does this recur on more machines, and what does it cost in scrap and stops? |
| A part measures outside tolerance | Operator: Should I measure again, stop the machine or call quality? | Quality: How many parts are affected, and is it the measurement or the process? | No question of its own | Engineering and planning: Is this a one-off or a change in the process? | No question of its own | No question of its own |
| Two operators, same part, different values | Operator: Am I measuring the right way? | Quality: How much of the variation comes from the measurement? | No question of its own | Engineering and planning: Does the measurement method or the fixture need to change? | No question of its own | No question of its own |
| The machine is down | Operator: Why did the machine stop, and what should I enter? | No question of its own | Production: Where do we lose the most time, and what should be fixed first? | Engineering and planning: Is the same reason recurring? | No question of its own | Management: Do the stops affect deliveries and capacity? |
| Changeover to the next part | Operator: Is everything done, and is the first part approved? | Quality: Has the first-piece inspection been done and documented? | Production: How long do changeovers take, and where does the time go? | No question of its own | No question of its own | No question of its own |
| The customer wants to see the requirement was met | No question of its own | Quality: Can we show that the requirement was met for this particular order? | No question of its own | No question of its own | IT: Where is the information, and is it connected? | Management: How confident are we that we can answer the customer? |
| Incoming material does not meet requirements | No question of its own | Quality: Is it the batch or our own process? | Production: Which orders are affected, and can we keep running? | No question of its own | No question of its own | Management: Is this a recurring problem with the supplier? |
| Quality work rests on a local system and a few key people | No question of its own | Quality: What do we need to keep from what we have today? | No question of its own | No question of its own | IT: What do operations, security and integrations look like in a new setup? | Management: How vulnerable are we if a key person leaves? |
