Characteristics
What is measured, against what, with what. A gauge whose resolution is a tenth of the tolerance cannot police it, and the gauge R&R figure is the honest statement of that.

The form
What is asked for when a record is created here. Required fields are marked; a choice drawn from a configuration list is one an administrator can extend without a release.
| Field | Type | Choices | Notes |
|---|---|---|---|
| Plan required | Choice | Looked up from existing records | |
| Line | Number | ||
| Characteristic required | Text | ||
| Data type | Choice | variable, attribute, visual, functional, destructive | Variable data can be charted; attribute data can only be counted. |
| Unit | Text | ||
| Target | Number | ||
| Specification minimum | Number | ||
| Specification maximum | Number | ||
| Classification | Choice | critical, major, minor, cosmetic | |
| Key characteristic | Yes or no | ||
| Method | Text | ||
| Gauge type | Text | ||
| Gauge | Choice | Looked up from existing records | |
| Gauge R&R % | Number | ||
| Sample size | Number | ||
| Frequency | Text | ||
| Charted on SPC | Yes or no | Enable for critical or key variable characteristics that need ongoing process monitoring. Inspection results are plotted on a control chart, and a point outside the control limits or a run trend raises an out-of-control signal for review. | |
| Subgroup size | Number |
The rules that apply here
Everything on this screen obeys the platform rules rather than rules of its own. The ones worth knowing before you use it:
- Narrowing a list — search, conditions, sort, totals, export and saved views.
- What may be changed — the five grounds a record may not be edited on.
- Companies and business units — what the switcher above this list is doing to it.
- Creating a record — required fields, where choices come from, and how the number is allocated.
- Importing a spreadsheet — this screen accepts one, and it runs through the same rules as typing.
