Risk calculation involves assessing, analyzing, and quantifying potential risks to an organization’s objectives, assets, or operations. It typically involves evaluating the likelihood of specific risks occurring and estimating the magnitude of their potential impact. By combining these assessments, organizations can calculate the overall risk level associated with particular scenarios or activities. 

There are various methods of risk calculation that you can implement in your organization. Some of these risk calculation methods are Failure Mode and Effects Analysis (FMEA), SWOT analysis, and TPRM.

Failure Mode and Effects Analysis (FMEA) involves identifying possible failure modes, determining their likelihood and severity, and prioritizing them based on risk to take proactive measures for mitigation. FMEA helps organizations improve reliability, safety, and performance by addressing potential issues before they occur, thus enhancing overall quality and efficiency.

 In this article, we will learn about the process of implementing FMEA in your organization. 

II. Understanding FMEA

What is FMEA?

FMEA stands for Failure Mode and Effects Analysis. It’s a systematic methodology used to identify and assess potential failure modes within a system, process, or product, along with evaluating their potential effects on operations or outcomes.

The primary goal of FMEA is to proactively identify and prioritize potential failures, determine their causes and effects, and develop strategies to mitigate or eliminate these failures before they occur. FMEA is widely utilized across various industries, including automotive, aerospace, healthcare, and manufacturing, to enhance product reliability, improve safety, and reduce the risk of failures.

The core principles of FMEA

The core principles of FMEA encompass several key concepts essential to its effectiveness:

1. Systematic approach

FMEA is not a one-time activity but rather a continuous improvement process. Organizations regularly review and update FMEA analyses to reflect changes in processes, technologies, or operating conditions, ensuring ongoing effectiveness in managing risks and enhancing performance.

6. Documentation and traceability 

Proper documentation of FMEA activities, including identified failure modes, causes, effects, and mitigation measures, is essential for accountability, traceability, and knowledge transfer within the organization. Documented FMEA results serve as valuable reference materials for future projects and decision-making.

Types of FMEA

There are several types of FMEA, each tailored to specific contexts and objectives:

1. Design FMEA (DFMEA) 

This type of FMEA focuses on identifying potential failure modes and their effects during the design phase of a product, system, or process. It aims to prevent or mitigate design-related failures before they occur, thereby improving product reliability and reducing development costs.

2. Process FMEA (PFMEA)

Process FMEA evaluates potential failure modes and their effects on manufacturing or operational processes. It helps organizations identify process weaknesses, error-prone areas, and opportunities for improvement to enhance quality, efficiency, and consistency in production.

3. System FMEA (SFMEA)

System FMEA assesses potential failure modes and their impacts at the system level, considering interactions among various subsystems or components. It helps organizations understand how failures within individual components or subsystems may affect the overall system performance or reliability.

4. Software FMEA

Software FMEA specifically addresses potential failure modes and their effects on software systems, applications, or algorithms. It focuses on identifying software-related defects, errors, or vulnerabilities that may compromise system functionality, data integrity, or security.

5. Service FMEA 

Service FMEA examines potential failure modes and their consequences within service-oriented processes or operations. It helps organizations identify risks associated with service delivery, customer interactions, and support activities, enabling them to improve service quality and customer satisfaction.

6. Hardware FMEA

Hardware FMEA concentrates on potential failure modes and their effects on physical components, equipment, or machinery. It aims to identify hardware-related failures, malfunctions, or defects that could impact product performance, safety, or reliability.

7. Environmental FMEA (EFMEA)

EFMEA evaluates potential failure modes and their effects related to environmental factors such as temperature, humidity, vibration, or chemical exposure. It helps organizations assess risks associated with environmental conditions and design products or processes to withstand or mitigate these risks.

FMEA automation

FMEA software streamlines Failure Mode and Effects Analysis by providing a structured framework for identifying failure modes, assessing their effects, and developing mitigation strategies. It supports collaboration among teams, manages data, prioritizes risks, and facilitates documentation and reporting. Integrating with other systems, it offers customization options to adapt to organizational needs, improving risk management efficiency and effectiveness. You can implement FMEA software to automatically perform FMEA analysis in your organization.

10-step guide to an FMEA analysis

Here are ten steps you can take to implement FMEA analysis in your organization:

Step 1: Identify failure modes

Failure modes refer to potential ways in which a system, process, or product can fail to meet its intended functionality or performance requirements. These modes represent specific scenarios or conditions that could lead to a loss of function, quality, or safety within the analyzed system.

Techniques for identifying failure modes

• Brainstorming: Engage multidisciplinary teams to generate ideas and scenarios that could lead to failures within the system or process.
• Historical data analysis: Review past incidents, breaches, or failures to identify recurring patterns or vulnerabilities.
• Fault tree analysis (FTA): Analyze the system’s structure and identify potential combinations of events or conditions that could lead to failures.

• Threat modeling: Systematically identify potential threats and attack vectors that could exploit weaknesses in cybersecurity defenses.
• Scenario analysis: Develop hypothetical scenarios or use cases to explore different failure modes and their potential impacts.

Step 2: Determine failure effects

Failure effects refer to the consequences or impacts resulting from the occurrence of a failure mode within a system, process, or product. These effects can range from minor disruptions to critical failures, potentially leading to financial losses, reputational damage, or safety hazards.

Techniques for determining failure effects

• Cause and effect analysis: Identify how each failure mode could propagate through the system and affect its various components or stakeholders.
• Scenario analysis: Explore hypothetical scenarios or use cases to understand the potential outcomes of each failure mode.
• Risk matrix: Assess the severity of failure effects by categorizing them based on their impact on business operations, compliance, safety, or customer satisfaction.

• Expert judgment: Consult subject matter experts or stakeholders to determine the potential consequences of failure modes based on their knowledge and experience.
• Historical data review: Analyze past incidents or failures to understand the real-world impacts of similar failure modes.

Step 3: Assess failure impact

Failure impact refers to the extent or magnitude of the consequences resulting from the occurrence of a failure mode within a system, process, or product. It quantifies the severity of the effects on various aspects such as safety, quality, compliance, financial, or operational performance.

Techniques for assessing failure impact

• Severity rating scales: Use predefined severity rating scales to assess the severity of failure impacts on a numerical scale (e.g., 1 to 10), considering factors such as financial loss, safety hazards, regulatory compliance, or customer satisfaction.
• Cost-benefit analysis: Evaluate the potential costs associated with failure impacts against the benefits of implementing preventive or corrective measures to mitigate risks.

• Expert judgment: Seek input from subject matter experts or stakeholders to assess the potential consequences of failure impacts based on their knowledge and experience.
• Historical data analysis: Analyze past incidents or failures to understand the real-world impacts of similar failure modes and estimate the potential consequences.
• Scenario analysis: Explore hypothetical scenarios or use cases to assess the potential outcomes of failure impacts under different conditions or circumstances.

Step 4: Rate failure severity

Failure severity refers to the degree of impact or harm that could result from the occurrence of a failure mode within a system, process, or product. It quantifies the seriousness or severity of the consequences, ranging from minor inconveniences to critical failures with significant implications.

Rating scales for severity assessment

Severity rating scales typically use numerical or qualitative descriptors to assess the severity of failure consequences. Common scales include:

• Numerical scale: Assign severity ratings on a numerical scale (e.g., 1 to 10), with higher numbers indicating greater severity.
• Qualitative scale: Use descriptive labels (e.g., Low, Medium, High) to categorize severity levels based on the potential impact of failure consequences.

Step 5: Identify root causes

Root causes are the underlying factors or fundamental reasons that contribute to the occurrence of failure modes within a system, process, or product. Identifying root causes is essential for understanding why failures occur and developing effective corrective actions to prevent recurrence.

Techniques for identifying root causes
