How is the calibration risk score calculated?

Each instrument is scored on criticality, usage frequency, drift or failure history, and current interval. You can edit weights to match your own risk policy.

Can I adjust the scoring model?

Yes. The weight inputs are editable and the formula is shown directly in the tool so teams can align it with internal procedures.

Is this suitable for audits?

It is a planning aid for prioritization and resource discussions. Final intervals and conformity decisions must follow your controlled calibration process.

Prioritization aid only. Final calibration intervals should be approved under your documented quality and risk procedures.

How to use this risk prioritizer

Use this score to focus limited calibration resources on instruments with the greatest consequence and instability. Start with your current policy weights, then adjust during team review.

Add all in-scope instruments in one session and sort by score.
Use the action category to plan tighten vs maintain vs relax reviews.
Export the table for audit preparation and management meetings.

Risk-based calibration FAQ

Can we change the model? Yes. Weight inputs are editable and normalized automatically.

Is this replacing procedures? No. It supports decision-making but does not replace your controlled method.

What if we have little history? Start with conservative assumptions and refine after each cycle.
