Education & research | Modelled case study
Authenticate data from shared scientific instruments
Can a result be attributed to the correct instrument, configuration, operator, and acquisition session?
The modelled organisation
A recognisable problem reaches the operating agenda
This composite scenario follows the Core Facility · Research Integrity · Instrument IT functions. It is grounded in the cited problem context but does not identify a real customer.
Operating environment
A university or research consortium combines student systems, federated identity, shared instruments, data repositories, partner institutions, and long-lived research records.
What is at stake
Open collaboration must coexist with durable privacy, research provenance, grant obligations, and identities that span institutions with different change windows.
Situation
Shared facilities export files through vendor workstations and removable media that do not preserve trustworthy machine or session identity.
Event that forces action
Core-facility automation, contested result, accreditation, or cross-border data exchange.
Concrete system boundary
Systems this case study puts in scope
The model is specific about the operational surfaces that must be discovered, changed, or independently checked.

Modelled case study walkthrough
How this organisation would use QNSI
The walkthrough connects the real-world problem to a bounded QNSI contribution and an independently reviewable result.
Recognise the operating condition
Shared facilities export files through vendor workstations and removable media that do not preserve trustworthy machine or session identity.
Frame the decision the owners must make
Can a result be attributed to the correct instrument, configuration, operator, and acquisition session?
Apply QNSI to the controlled boundary
Associate QNSI-supported machine signatures with instrument asset, calibration state, method, operator session, and file digest.
Leave the team with a concrete result
An instrument-origin evidence record linking raw data to equipment identity, configuration, and acquisition context.
Prove the result in the organisation's environment
The facility validates calibration, method controls, operator identity, timestamping, vendor software, and research policy.
What useful success looks like
A decision artifact plus proof from the real environment
The model stops at a target result. It becomes an actual case study only when a customer produces and independently validates this evidence in production.
Decision artifact
An instrument-origin evidence record linking raw data to equipment identity, configuration, and acquisition context.
Independent validation boundary
The facility validates calibration, method controls, operator identity, timestamping, vendor software, and research policy.
Real-world problem grounding
Primary sources behind the model
These sources establish the external requirement, failure mode, or risk context used to model this case. They do not endorse HEOSSI or prove that QNSI completed the scenario.
Customer evidence status
This is modelled, not a customer claim
The organisation is a composite and the result is a target state. This page does not prove a deployment, customer outcome, certification, legal conclusion, regulator endorsement, or completed control.
