What is a Reliability Engineer? Roles, Skills, and Certifications

Maintenance departments look at different strategies based on the industry and company. You could have:

• Preventive: This proactive approach focuses on preventing equipment failures before they occur.
• Predictive: This data-driven approach utilizes sensors and other monitoring tools to track equipment health and predict potential failures.
• Corrective: This reactive approach addresses problems after they arise.
• Condition-Based: This approach combines aspects of preventative and predictive maintenance.
• Reliability-Centered (RCM): This comprehensive approach focuses on optimizing maintenance strategies for specific equipment based on its criticality and failure modes.

Of course, many departments use a combination of the above. However, in this article, we'll focus on the last type. Reliability. Specifically, the reliability engineer.

Key Responsibilities of a Reliability Engineer

At their core, reliability engineers solve problems. Their primary focus lies in maximizing the lifespan and functionality of equipment, minimizing downtime, and preventing costly failures. They achieve this through a multifaceted approach that encompasses:

• Risk Management: Reliability engineers identify potential weaknesses and failure points within systems. They employ various techniques, to assess risks and develop mitigation strategies. These include Failure Mode and Effects Analysis (FMEA). This proactive approach prevents problems before they snowball into major disruptions.
• Proactive Maintenance: Note the difference between reactive and preventive maintenance. One tends to problems after they occur. While this may seem similar to corrective maintenance, reactive doesn't employ ANY stopgap measures.
• Technicians will have corrective repairs as part of their PM strategy because of the nature of machines.
• Reliability engineers champion preventative maintenance practices. This includes implementing regular inspections, scheduling part replacements, and establishing lubrication routines.
• Data Analysis and Root Cause Identification: When failures do occur, reliability engineers don't shy away. They meticulously analyze data from various sources. Sensor readings. Maintenance logs. Failure reports.

This in-depth analysis helps them pinpoint the root cause of the issue. They have targeted solutions and seek to prevent similar occurrences in the future.

• Continuous Improvement: Reliability engineers actively seek ways to:
• ⮚ Optimize maintenance practices.
• ⮚ Refine procedures.
• ⮚ Implement new technologies that enhance reliability.

This approach ensures that systems and equipment operate at peak efficiency over time.

A typical day for a reliability engineer blends analytical work, hands-on tasks, and collaboration.

• Data Analysis: Reliability engineers spend a significant amount of time analyzing data from various sources. This data helps them identify trends, predict potential failures, and assess the effectiveness of maintenance programs.
• Developing Maintenance Plans: They create comprehensive maintenance plans that outline procedures for inspections, replacements, and repairs. These plans ensure that equipment receives the necessary attention to maintain optimal performance.
• Collaboration: Reliability engineers collaborate with various stakeholders, including maintenance technicians, operations personnel, and design engineers. This collaboration facilitates information sharing, problem-solving, and the implementation of effective reliability practices.
• Staying Updated: The field of reliability engineering constantly evolves. To stay ahead of the curve, reliability engineers continuously learn about new technologies, best practices, and industry standards.

Certifications to Advance Your Reliability Engineer Career

A bachelor's degree in engineering, science, or a related field precedes a person achieving the title of a reliability engineer. However several certifications can enhance one's qualifications and expertise.

Certified Reliability Engineer (CRE): Offered by the American Society for Quality (ASQ). This certification validates an individual's knowledge and skills in core reliability engineering principles.

Certified Maintenance & Reliability Professional (CMRP): This comes from the Society for Maintenance & Reliability Professionals (SMRP). It demonstrates a professional's competency in maintenance and reliability practices.

Certified Six Sigma Black Belt: This methodology for process improvement signifies expertise in using this methodology to minimize defects and improve efficiency.

How a CMMS Supports Reliability Engineers

A Computerized Maintenance Management System (CMMS) streamlines maintenance operations. It acts as a powerful tool for reliability engineers, empowering them in several significant ways:

• Improved Data Collection and Analysis: CMMS software facilitates the collection of maintenance data.
• ⮚ Work order history.
• ⮚ Equipment performance metrics.
• ⮚ Spare parts inventory levels.
• This readily available data allows reliability engineers to:
• ⮚ Perform in-depth analysis.
• ⮚ Identify trends.
• ⮚ Make data-driven decisions to optimize maintenance strategies.
• Enhanced Maintenance Planning and Scheduling: CMMS helps in creating and managing preventative maintenance schedules.
• Streamlined Work Order Management: CMMS allows for efficient work order creation, assignment, and tracking. This ensures that the right workers complete maintenance tasks on time.
• Inventory Optimization: The system helps manage spare parts inventory. It tracks parts usage, identifies reorder points, and minimizes the risk of stockouts. Parts stay readily available when needed, preventing delays in maintenance activities.
• Improved Communication and Collaboration: CMMS acts as a central repository of maintenance information. This facilitates communication and collaboration between reliability engineers, maintenance technicians, and other stakeholders.
