What exactly is a Safety Management System (SMS)?
A Safety Management System (SMS) is a systematic and explicit approach to managing safety, encompassing the necessary organisational structures, accountabilities, policies, and procedures. It essentially applies the rigour of quality management principles to the domain of operational safety.
Unlike traditional, fragmented safety programmes that might rely solely on compliance checks and retrospective accident investigation, an SMS treats safety as a core business function. It mandates a top-down, structured effort to ensure that safety risk is managed to an acceptable or tolerable level, a level defined by the organisation and often dictated by regulatory bodies.
The essence of a robust SMS lies in its ability to facilitate effective, risk-based decision-making across all echelons of a company, from the boardroom to the front line. It moves an organisation from a reactive mindset (responding to incidents) to a proactive and predictive one (identifying and mitigating hazards before they manifest).
The evolution of safety: From QMS to SMS
To truly understand the power of an SMS, it helps to understand its origins. As outlined by Michele, SMS Manager at Airbus Protect, the progression from previous systems to SMS represents a maturation of the aviation and aeronautics industry’s approach to safety. (It is worth noting that while SMS is the gold standard in aviation, other high-risk sectors, such as the space industry, often rely on their own specific product assurance and safety frameworks).
• The Early Focus on Investigation: Historically, the conduction of research and development studies was initiated to improve safety. The approach taken in the past involved investigating the reasons behind safety issues and analysing the problems to prevent recurrence. Initial feedback mostly considered mechanical failures or weather-related events, eventually shifting to include human factors.
• Understanding Organisational Factors: Many people historically believed humans make mistakes and errors due to their personality traits or knowledge. However, after several years, this mindset changed; studies investigating human error revealed that errors are not a result of bad human behaviour, but rather a natural phenomenon within each human being. As a result, the term “organisational factors” was created to describe accidents or incidents that derive from organisational decisions and attitudes.
The Journey of Management Systems
• Quality Management System (QMS): The QMS was one of the first major steps a formal system implemented to manage business processes with a focus on product and service quality. QMS covers the set of ways of working, rules, and roles defined to achieve company quality policy and objectives, ensuring business activities comply with requirements. This system was concerned with fulfilling customer and stakeholder expectations, delivering products with the right quality, at the right time, and at the right cost. However, it soon became evident that quality and safety were not one and the same. QMS was not designed to manage the full scope of safety risks, especially those related to human and organisational factors.
• Business Management System (BMS): This realisation led to the development of a more encompassing framework: the BMS. The BMS covers a consistent view of the company and their activities, enabling management to make informed decisions to optimise their ways of working. It identifies the principles of a successful organisation and serves as a set of tools for the strategic planning and tactical implementation of business plans.
• Safety Management System (SMS): Building on the foundations of Business Management Systems (BMS), the Safety Management System (SMS) represents the most sophisticated evolution of this approach. While Quality Management Systems (QMS) and SMS share a structural lineage, their objectives diverge: SMS focuses specifically on proactively identifying hazards and fostering a robust safety culture, a necessity in high-stakes industries. By leveraging both reactive and proactive data analysis, it systematically preempts risks before they escalate.
Ultimately, the paradigm has shifted from a narrow focus on product quality (QMS) to a holistic, enterprise-wide perspective (BMS) that enshrines safety as a core operational value. Consequently, SMS does not merely exist alongside a BMS; it serves as a critical, high-performance layer that can be seamlessly woven into an Integrated Management System (IMS).
What is an SMS for, and what are its core functionalities?
The objective of an SMS is fundamentally to provide a structured management approach to control safety risks inherent in operational processes. It is a fundamental tool used to achieve and maintain superior safety performance.
The SMS serves several critical interconnected purposes through these core functionalities:
• Systemic Risk Control: It ensures that every activity within the organisation is scrutinised for potential hazards, allowing for the identification, assessment, and control of risks in a systematic, repeatable manner.
• Continuous Improvement: By establishing performance indicators and assurance mechanisms, an SMS ensures that safety management is an ongoing, dynamic cycle, not a static state.
• Compliance and Due Diligence: It provides the framework for meeting complex regulatory requirements. By demonstrating a formal, auditable system for managing safety in accordance with bodies like the European Union Aviation Safety Agency (EASA), the Federal Aviation Administration (FAA), or national authorities, a company fulfills its corporate due diligence obligations.
Why is SMS important for a company?
The rationale for implementing an SMS is typically divided into three compelling drivers:
