Summary
In short
- A statistical process control log is a log used in KnowQuality that records measurements over time so process variation can be seen and acted on before product fails. It is built against ISO 7870 and forms part of the HACCP and Food Safety programme.
- Completed at set intervals. Carried out by the operator.
- The template holds 45 fields across 4 sections, with readings repeating for each entry.
- Scoring is capability index, where high is good.
- ISO is international Organization for Standardization. A voluntary international standard. Widely adopted, often required by customers, and certifiable where a management system standard.
- It connects to the rest of the library: links Control Plan, Asset.
What it is

What is a statistical process control log?
A statistical process control log is a log used in KnowQuality that records measurements over time so process variation can be seen and acted on before product fails. It is built against ISO 7870 and forms part of the HACCP and Food Safety programme.
When is a statistical process control log completed?
A statistical process control log is completed continuously, as entries occur. Completed at set intervals.
When to use it
When to use it, and when not to
This log 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 log covers has occurred, or is about to
- A new record is needed; each one gets its own ID in the form SPC-2026-000
- You are running the HACCP and Food Safety programme and this is one of its steps
- A linked record needs this one to exist: links control plan, asset
Not for
- Control Plan, which sets out what is measured on a process, how often, by what method and what to do when it goes out of limits.
- Process Capability Study, which measures whether a process can reliably hold its specification, using data from a stable run.
- Setup Approval Record, which confirms a new setup is correct and approved before the run continues past the first pieces.
- Anything outside KnowQuality, which belongs in the workspace that owns that process

FAQ
Frequently asked questions
What is the statistical process control log template based on?+
It is built against ISO 7870. 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 control log contain?+
There are 4 sections: header, readings, pattern checks, response. Together they hold 45 fields, 29 of which are required.
How often is a statistical process control log raised?+
A new record is raised continuously, as entries occur. Each one is given an ID in the form SPC-2026-000, so it can be traced and referenced from other records.
Which programme does the statistical process control log belong to?+
It is part of HACCP and Food Safety, Statistical Process Control. A HACCP system an auditor can follow from hazard to record without asking a single question.
How is a statistical process control log 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 control log 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 control log 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.
