Critical Control Management
Understanding Critical Control Management (CCM) in myosh
Introduces Critical Control Management (CCM) concepts, terminology, and processes, including how critical control effectiveness is verified, often using the Inspections & Audits module.
- Identifying MUEs relevant to your operations (using the "Critical Risk Assessment" form).
- Identifying controls for these MUEs (using the "Controls" form).
- Determining which controls are critical.
- Establishing how critical controls should perform and be verified (using linked Performance Standard forms).
- Regularly checking that critical controls are effective. These verification activities can take various forms, such as physical checks, performance tests, or detailed assessments. Such activities are often conducted and documented using custom forms built within the Inspections & Audits module. The outcomes of these verifications are then tracked via "Critical Control Verification" records within the CCM module.
- Monitoring and improving your CCM system.
Key Terminology You'll Encounter
- Critical Risk Assessment (MUE): A record of a significant, high-consequence event your organisation wants to prevent. This is the central point of a Bowtie diagram.
- Control: A measure to prevent an MUE or reduce its impact.
- Preventative Control: Aims to stop the MUE. Shown on the left side of a Bowtie.
- Mitigating Control: Aims to lessen the impact if the MUE occurs. Shown on the right side of a Bowtie.
- The "Preventative/Mitigating" field on a Control record determines its type and Bowtie placement.
- Critical Control: A control deemed crucial.
- The "Critical/Non Critical" field designates this, often guided by a "Criticality Decision Tree" in the form. Being "Critical" often unlocks further fields for performance standards.
- Performance Standard/Requirement: For Critical Controls, these detail how the control should perform, how it's verified, its parameters, and potential failure modes. These are documented in linked forms: "Performance Requirement," "Performance Activity," "Performance Parameter," and "Failure Mechanism."
- Verification: The process of checking if a critical control is working as intended. This can result in a "Critical Control Verification" record.
