Part 1 of 4

Start with the intended use

View technical information · Diagram 1
Start with the intended use — diagram 1. Description below.
The diagram connects patient need to the vessel's intended purpose and the evidence needed to support that purpose. Key points: Patient need; System purpose; Evidence. Use the image link to enlarge.

Lesson explanation

Welcome to Module 2. Our fictional project is a jacketed mixing vessel used to prepare an aqueous oral solution before filling. It is not an aseptic process. We will follow the project from planning to a review decision. Begin by asking what product the system supports, how it will be used, and what could go wrong. A polished protocol cannot rescue an undefined purpose.

Three connected documents

View technical information · Diagram 2
Three connected documents — diagram 2. Description below.
The three document roles are programme planning in a VMP, intended needs in a URS, and prioritization through risk assessment. Key points: VMP: programme; URS: need; Risk: priorities. Use the image link to enlarge.

Lesson explanation

The validation master plan describes the programme. The user requirements specification describes what the system must do. The risk assessment explains where failures matter and how controls will be justified. In this course we say VMP and URS. These documents should agree with one another. If the vessel needs controlled mixing, the requirement, risk discussion and verification evidence should all address that need.

The evidence journey

View technical information · Diagram 3
The evidence journey — diagram 3. Description below.
The three stages are defining needs, verifying them with evidence, and maintaining control after qualification. Key points: Define; Verify; Maintain. Use the image link to enlarge.

Lesson explanation

Imagine buying a vessel because the catalogue says pharmaceutical grade. That description does not establish fitness for our product. The team still needs to understand contact materials, cleaning, measurement, mixing and records. The illustration connects a product vessel to its temperature sensor and control panel. These are functional interfaces, not a construction drawing. The same intended use must guide design review, testing and routine operation.

Your first decision

View technical information · Diagram 4
Your first decision — diagram 4. Description below.
The decision path identifies evidence gaps, assigns owners and requires resolution before routine use. Key points: Identify gaps; Assign owners; Resolve before use. Use the image link to enlarge.

Lesson explanation

For the first activity, describe the vessel's intended use in three sentences. Identify the product family, operating purpose and important interfaces. Then list information that is still missing. Do not invent operating limits to complete a form. Assign each missing item to an appropriate owner, such as process development or engineering. Planning is useful when it exposes uncertainty early enough to change the project.

Write a three-sentence intended-use statement and identify three unknowns.

Compare with model reasoning

Example: vessel V-201 prepares a defined aqueous oral-solution product family before transfer to filling. It mixes within the established batch-volume range and interfaces with approved utilities and a controlled transfer path. Confirm viscosity range, cleaning strategy and required measurement performance with their owners.
