Control is a daily practice
Most quality systems are tested once a year, by an auditor, over a few days. The rest of the time they are assumed to work.

Control every day
What it takes for a quality system to stay in a state of control between audits.
Placeholder PDF · A4 and US Letter · page count to be confirmed
The thesis
We apply that definition to the quality system itself: the evidence it produces on ordinary days, from deviations and nonconformities to corrective and preventive actions (CAPA), effectiveness checks and management review, and how to read that evidence as signal or as routine variation.

The flagship exhibit
Each claim sits beside the exhibit that supports it. Center line and limits are drawn from the series itself.
Exhibit 1
Illustrative data
In this illustrative series, one week falls outside the upper control limit
Deviations recorded per week, one site, 20 weeks, count; center line and limits from the same series
Note: Values are placeholders chosen to demonstrate the exhibit format. CL is center line; UCL and LCL are upper and lower control limits. The signal in week 12 is marked with a filled marker and a label.

From the notes
Exhibits are numbered within each piece. Scroll sideways for more.
Exhibit 1 / Definitions
Illustrative data
In this illustrative register, deviations outnumber the other three record types
Quality records opened by type, one site, one quarter, count
Note: Values are placeholders chosen to demonstrate the exhibit format. Each record type is counted separately.
Source: Illustrative data for layout purposes only; not research findings.
From: Nonconformity, deviation, observation and finding mean different things
Exhibit 1 / CAPA
Illustrative data
In this illustrative CAPA, the effectiveness check takes longer than the action it verifies
Median days in each CAPA stage, one site, one year, days
Note: Values are placeholders chosen to demonstrate the exhibit format. Stages are shown in process order. CAPA is corrective and preventive action.

Exhibit 1 / Inspection readiness
Illustrative data
In this illustrative site, more than four in ten open records are older than their target closure time
Open quality records by age band, one site, at one date, count; illustrative target closure time 60 days
Note: Values are placeholders chosen to demonstrate the exhibit format. Age bands are in natural order. Bands past the 60-day target are shown in Forest: 23 of 54 open records.

Method
Signal or routine variation
Every exhibit draws its center line and limits from the series itself, so a reader can tell a real signal from ordinary variation. Placeholder copy.

Audit day is a sample of one
An audit tests a quality system over a few days. The other days of the year are where control is kept or lost.
