# Validation and computer software assurance
Validation is the documented evidence that a system, a piece of equipment or a process does what it is intended to do, consistently. QLogixCMC plans and runs validation that is scaled to risk: computer software assurance for computerized systems, qualification of equipment and utilities, and process validation across its three stages, with the evidence written so an inspector can follow it.

## What we validate
- Computerized systems: QMS, LIMS, MES, ERP, CMMS, document management and laboratory instruments
- AI-enabled and agentic systems: intended use, risk assessment, test evidence and monitoring in use
- Equipment and utilities: design, installation, operational and performance qualification
- Processes: process design, process performance qualification and continued process verification
- Cleaning validation and analytical method validation support
- Data integrity controls and audit trail review procedures

## How the work runs
A validation master plan sets the approach, the risk model and the deliverables for the site or the program. Each system or process then gets a risk assessment that decides how much testing it needs: a high-risk function that affects product quality or patient safety is scripted and witnessed; a low-risk one is covered by unscripted or ad hoc testing with the result recorded, as FDA's computer software assurance guidance allows.
Protocols are written from the user requirements and the risk assessment, executed with the people who will run the system, and reported with every deviation resolved. Supplier assessments and vendor documentation are used where they are adequate, so testing is not repeated for its own sake.

## Validating AI-enabled systems
AI functions in a GxP system are validated by defining the intended use, assessing the risk of a wrong output, testing against acceptance criteria on a representative set of records, keeping the model and the prompts under change control and monitoring performance in use. Human review of the output is a control in the risk assessment, not a reason to skip validation.
- Intended use and the boundary of what the AI may and may not do
- Risk assessment of wrong, missing or misleading output
- Test sets with known answers, acceptance criteria and the evidence of the run
- Change control for model, prompt and configuration updates
- Periodic review against the baseline performance

## Your qualified people decide
- Your validation lead or quality unit approves the master plan, each risk assessment and each report.
- Release of a system, a piece of equipment or a process for GMP use is a decision of your qualified people.

## Frameworks this work is built to
- GAMP 5 (2nd ed.)
- FDA CSA guidance
- 21 CFR Part 11
- EU GMP Annex 11
- EU GMP Annex 15
- FDA Process Validation guidance
- ICH Q9(R1)
- EU GMP Annex 22 (draft)

## Included
- Validation master plans
- CSV and CSA
- Equipment qualification
- Process validation
- AI-enabled systems
- Periodic review

## Questions about validation and computer software assurance

### What is computer software assurance?

Computer software assurance (CSA) is FDA's risk-based approach to establishing confidence in software used in production and the quality system. Testing effort follows the risk of the function: high-risk functions get scripted, documented testing; lower-risk functions get unscripted or ad hoc testing with the result recorded. It replaces the uniform, document-heavy approach of traditional CSV.

### Do you accept vendor validation packages?

Where they are adequate, yes. QLogixCMC assesses the supplier and the package against your intended use and risk assessment, uses what covers your use, and tests only what the package does not cover or what is configured for your site.

### Can AI functions be validated at all?

Yes. QLogixCMC validates AI functions by defining the intended use, assessing the risk of wrong output, testing against acceptance criteria on records with known answers, placing the model and prompts under change control and monitoring performance in use. The draft EU GMP Annex 22 sets out the same expectations.

### How is validation documented for an inspection?

With a validation master plan, a risk assessment per system or process, user requirements, protocols with executed evidence, deviation records and a summary report that states whether the system is fit for its intended use. Every document is approved by your quality unit before the system is released.

## Talk it through with someone who has run a plant
Bring your backlog, your submission timeline or the Form 483. We will tell you plainly what we would do first, what it would take, and what we would leave alone.
[Request a meeting](https://qlogixcmc.com/contact)[Email us](mailto:contact@qlogixcmc.com)

In the first meeting we cover
- What is on your mind: a backlog, a submission, a validation program, an inspection date or a system that is not working
- What we would assess first, and what we would leave alone
- Whether an engineer on your site, a fixed-scope assessment or a defined deliverable is the right way to start
