Part 1 of 4

From design to installation

View Technical Explanation · Diagram 1
From design to installation — diagram 1. Description below.
The design baseline and installed system feed one comparison; neither input alone establishes conformity. Key points: Approved design; Installed configuration; Documented comparison.

Lesson explanation

Welcome to Module 4, Installation Qualification, or IQ. We continue with the fictional V-201 oral-liquid mixing vessel. The design review described what was intended. Now the team compares the installed system with the accepted design and manufacturer recommendations. Every identifier and observation in this module is invented for training. No real equipment has been qualified.

Part 2 of 4

Three different evidence questions

View Technical Explanation · Diagram 2
Three different evidence questions — diagram 2. Description below.
The three stages form a sequence of different evidence questions, not three interchangeable approvals. Key points: DQ: proposed design; IQ: installed system; OQ: challenged operation.

Lesson explanation

A drawing shows a temperature sensor connection. A walkdown identifies which sensor is installed at that connection. An operational challenge examines how the assembled loop behaves. These answer different questions. Finding the correct tag does not demonstrate alarm response, and a successful alarm test does not repair missing material identification. Keep each conclusion tied to the evidence actually obtained.

Part 3 of 4

Set the system boundary

View Technical Explanation · Diagram 3
Set the system boundary — diagram 3. Description below.
The vessel boundary includes its connections; upstream utility qualification remains a separate linked scope. Key points: Vessel and components; Utility interfaces; Control-system interfaces.

Lesson explanation

For our case, the installation boundary includes the vessel, agitator, outlet components, instruments and defined utility connections. The upstream utility plant has its own qualification scope. Record where one system ends and another begins. A qualified water system does not automatically prove that a new branch has the correct connection or that its delivered water is suitable.

Part 4 of 4

Limit the conclusion

View Technical Explanation · Diagram 4
Limit the conclusion — diagram 4. Description below.
Installation findings feed a bounded conclusion and a next-stage decision; routine production is outside this diagram. Key points: Installation evidence; Open findings; Next-stage decision.

Lesson explanation

The teaching conclusion is limited to installation evidence reviewed against the defined baseline. It is not permission to manufacture a batch. Operational and performance verification remain separate needs. Where stages are combined in an approved approach, the underlying evidence questions still remain visible. Your first activity separates installation observations from claims that require later studies.

Worked example

Fictional worked example — not an approved site record
ObservationSupported conclusion
Sensor serial matches scheduleInstalled identity matches this baseline
Alarm challenge not executedNo alarm-performance conclusion
No product studyNo blend-uniformity conclusion

Apply it · Activity 1

Classify: sensor serial matches schedule; alarm stops heating; batch blend is uniform. Explain the evidence boundary.

Open workbook activity
Compare with model reasoning

The first is installation identity evidence. Alarm response needs a defined operational challenge. Blend uniformity needs a justified performance/process study; neither is proven by identity alone.
