Sofema Online (SOL) considers the relationship and practical considerations related to an effective CMS & SMS
The effective implementation of both a Compliance Monitoring System (CMS) and a Safety Management System (SMS) is a regulatory driven obligation. However, despite regulatory expectations for synergy, many organisations continue to treat CMS and SMS as standalone activities, leading to operational inefficiencies and missed opportunities.
What is the Difference Between Compliance and SMS?
- Compliance Monitoring is focused on ensuring that the organisation continues to meet regulatory and internal requirements. It involves systematic audits, process reviews, and documentation checks to verify conformance and to identify any non-compliance or systemic weaknesses.
- Safety Management System (SMS), on the other hand, is concerned with the identification of hazards, assessment of safety risks, and the monitoring of safety performance. It aims to proactively manage risks before they manifest into incidents.
In essence:
Compliance Monitoring answers: “Are we doing what we are required to do?”
SMS asks: “Are we doing what we need to do to be safe?”
Both systems are not mutually exclusive — rather, they should interact and complement each other. Together, they create a comprehensive framework that enables the organisation to not only remain compliant but also to manage operational risk effectively.
Challenges in the CMS-SMS Relationship
- a) Operational Silos
Many organisations still operate CMS and SMS in parallel but in isolated structures. CMS is frequently embedded within Quality or Compliance Departments, while SMS is managed separately by Safety or Operational Risk Teams.
- This disconnection hinders the flow of data and weakens the feedback loop necessary for informed decision-making.
- b) Lack of Cross-Functional Integration
There is often no formal mechanism to ensure that:
- Audit findings (from CMS) feed into the SMS hazard and risk registers, or
- Safety issues (from SMS) trigger deeper compliance reviews or targeted audits.
This disconnect undermines the concept of an integrated management system and leads to missed opportunities for learning and improvement.
- c) Resource and Training Gaps
Auditors are not always trained to recognise safety risks beyond regulatory conformance, and SMS managers may lack insight into the value of compliance data in strengthening risk controls. This results in partial oversight and an over-reliance on reactive rather than proactive measures.
Audit Implications for CMS and SMS
In an integrated environment:
- Compliance audits should not only assess conformity but also consider how non-compliances might contribute to safety risk.
- SMS reviews should be guided by data from compliance monitoring (e.g., repeated findings, unclosed actions, or systemic process failures).
- Audit scopes should be risk-based, using SMS data to prioritise high-risk areas and ensure alignment with operational safety objectives.
- Root cause analysis of audit findings should reflect both compliance and safety implications, promoting systemic rather than superficial corrective actions.
The challenge for operators is to move beyond structural separation and legacy thinking. By fully integrating CMS and SMS processes, organisations unlock the full potential of their management systems, achieving not just regulatory compliance, but true operational safety excellence.
