Summary
In short
- A statistical process capability study is an assessment used in KnowQuality that establishes whether a process can consistently hold the tolerance it is asked to hold. It is built against ISO 9001 cl.8.5 and forms part of the Statistical Process Control programme.
- Carried out on new processes and after change. Completed by quality engineering.
- The template holds 52 fields across 5 sections.
- Scoring is capability index, where high is good.
- ISO 9001 is quality management systems. The international standard for consistently meeting customer and regulatory requirements. Certifiable.
- It connects to the rest of the library: links SPC, Change control.
What it is
What it is
What is a statistical process capability study?
A statistical process capability study is an assessment used in KnowQuality that establishes whether a process can consistently hold the tolerance it is asked to hold. It is built against ISO 9001 cl.8.5 and forms part of the Statistical Process Control programme.
When is a statistical process capability study completed?
A statistical process capability study is completed when the task, area or population being assessed is new or has materially changed. Carried out on new processes and after change.
When to use it
When to use it, and when not to
This assessment is one step in a larger programme. Using it for work that belongs to a neighbouring template produces records that are hard to report on later.
Use it for
- The event or activity this assessment covers has occurred, or is about to
- The workspace is being set up, or the register needs an entry added or retired
- You are running the Statistical Process Control programme and this is one of its steps
- A linked record needs this one to exist: links spc, change control
Not for
- Manufacturing First Article Inspection, which inspects the first part or pack off a setup against every specified characteristic before the run continues.
- Statistical Process Control Chart Review, which reviews control charts for a characteristic to see whether the process is stable and capable, not merely in specification.
- Gauge Repeatability and Reproducibility Study, which measures how much of the observed variation comes from the measurement system rather than the process.
- Anything outside KnowQuality, which belongs in the workspace that owns that process

FAQ
Frequently asked questions
What is the statistical process capability study template based on?+
It is built against ISO 9001 cl.8.5. ISO 9001 is quality management systems. The international standard for consistently meeting customer and regulatory requirements. Certifiable. ISO is international Organization for Standardization. A voluntary international standard. Widely adopted, often required by customers, and certifiable where a management system standard.
What sections does the statistical process capability study contain?+
There are 5 sections: header, data, results, conclusion, result. Together they hold 52 fields, 43 of which are required.
How many statistical process capability study records should we have?+
This is a singleton. One record per workspace, set up once and maintained, rather than one per event. Other templates refer back to it.
Which programme does the statistical process capability study belong to?+
It is part of Statistical Process Control. Processes judged in control before they are judged capable, with the gauge ruled out first.
How is a statistical process capability study scored?+
Scoring is capability index. High is good. Scores exist to make the form tell you something, not to produce a percentage for its own sake.
Can the statistical process capability study template be changed?+
Yes. Every field, option, score and conditional rule is editable, and the links to other templates come with it. Most teams install it as it is, run it for a cycle, then adjust.
The agents
What the agents do with it
The form is the easy part. Keeping it current, routing it to the right owner and holding the evidence together is the work that actually slips.
Holds the statistical process capability study library against your registers, routes each record to its owner, and keeps the evidence trail together.
Coordinates the crew, rolls completion and exceptions into one view, and holds every write for your approval before it touches a record.
This template lives in KnowQuality — quality and food safety. HACCP, nonconformance, traceability, laboratory and customer complaints.
