When a failure happens, you want to find out why and take action to prevent future occurrence. To do this you must capture as much evidence - verbal, physics, digital - as possible. This presentation discusses that.
The document discusses how to implement a Failure Reporting, Analysis, and Corrective Action System (FRACAS) to improve equipment availability. It recommends capturing comprehensive failure data, conducting a root cause analysis to identify the underlying causes, and developing a corrective action plan. Implementing FRACAS effectively can help eliminate most failures through preventative actions, resulting in increased availability and decreased costs while keeping customers satisfied. The key is for maintenance professionals to have the right system and accountability to track failures from data collection through implementing solutions.
Want a practical approach to reducing Failures in your organization? Thing simple however think Big when it comes to an approach. This is not a recipe, it is an idea for you to expand on. Make it your own however their are ideas which are solid. Make a difference today in reducing failures.
This document discusses Failure Reporting, Analysis and Corrective Action System (FRACAS), a system for recording equipment failures, analyzing patterns in failure data, and making business decisions based on conclusions. It outlines how to implement FRACAS using failure codes in a Computerized Maintenance Management System (CMMS) to identify top failure modes across equipment and implement corrective actions. The presentation notes biggest challenges are getting accurate failure analysis data recorded in the CMMS and completing the failure modes library, and provides a multi-step implementation plan starting with critical equipment.
This document discusses the Failure Reporting, Analysis and Corrective Action System (FRACAS) process for identifying equipment failures and eliminating or mitigating their effects. FRACAS involves analyzing failure reports from maintenance management systems to identify common failure patterns, defects, and causes across assets. This allows organizations to focus reliability improvements on eliminating recurring failures. The document provides examples of how to validate an equipment hierarchy, conduct a criticality analysis, and develop failure codes to track specific failure modes in order to continuously improve maintenance strategies through the FRACAS process.
Why do people not understand the P-F Curve? At a recent maintenance function, I asked 70 maintenance and reliability professionals how many of them had heard of the P-F Curve and only about 10% stated they had. From that 10%, only 1% felt like they truly understood it. This was shocking to me. I assumed everyone had heard about the P-F Curve and its intent.
The intent of the P-F Curve is to illustrate how equipment fails and how early detection of a failure provides time to plan and schedule the replacement or restoration of a failing part without interruption to production or operations.
Once you understand the P-F or PF Curve you will have a better awareness of how equipment fails.
At the end of the year or month what reports would you like to see from your CMMS/EAM? Would you like a few failure reports? Check out this presentation. It may make your day.
Reliability Centered Maintenance (RCM) is a process that determines the best policies for managing asset functions and failures. It considers all asset management options like condition monitoring, scheduled restoration, and scheduled discard. RCM provides the optimal mix of reactive, time-based, condition-based, and proactive maintenance practices. When applied to commercial airlines in the 1970s, RCM reduced equipment-related crashes from 40 to 0.3 per million take-offs.

Is Reliability Centered Maintenance (RCM) right for you?Nancy Regan
This presentation outlines the goals of a Reliability Centered Maintenance (RCM) analysis. It debunks the top misconceptions about RCM. And it poses and answers the top four questions about RCM most people don’t know to ask.
Reliability centered maintenance (RCM) is a maintenance strategy that uses failure modes and effects analysis to determine the most cost-effective maintenance tasks. It aims to perform only necessary maintenance to preserve system functions and avoid unnecessary maintenance costs. RCM shifts maintenance from reactive to condition-based, using tools like vibration analysis and oil testing to predict failures. Initial costs for RCM are higher but maintenance costs decrease over time as failures are prevented.
The document discusses methodology for maintenance, specifically preventive maintenance. It describes four main functions of maintenance as maintaining, keeping in existing condition, preserving, and protecting from failure or decline. Preventive maintenance is classified as either corrective or preventive. Preventive maintenance aims to prevent or mitigate failures from occurring and can be time-directed, condition-directed, or failure-finding. The document also discusses reliability centered maintenance and its features, including preserving system function over equipment. It outlines the seven-step methodology for implementing reliability centered maintenance on systems.
The document outlines three primary steps in maintenance reliability engineering:
1. Measure availability and identify failure-prone equipment by calculating metrics like MTBF, MTTR, and MLDT.
2. Perform root cause failure analysis to determine the underlying causes of failures and their costs.
3. Develop and implement corrective job plans using reliability centered maintenance principles to eliminate causes and manage failures, aimed at increasing availability and reducing costs over time.
This document contains a summary of a presentation on best practices in maintenance and reliability by Ricky Smith. It discusses key topics like reliability definitions, failure patterns, predictive maintenance, FRACAS systems, and reliability metrics. It emphasizes that most equipment failures are self-induced due to issues like improper installation, maintenance, or lubrication. It also outlines steps for improving reliability like prioritizing assets, identifying maintenance strategies, and using failure data for continuous improvement. The goal is to move from reactive to proactive maintenance through practices like condition monitoring and root cause analysis.

The document outlines the general FMEA process which involves selecting a team, brainstorming failure modes and their causes/effects, assigning ratings, calculating risk priority numbers, and defining actions to address high risks. It provides guidance on team composition and dynamics, as well as tips for effectively conducting and documenting an FMEA.
The Antidote to Implementation Failure in the World of Asset ManagementNancy Regan
This presentation details how implementation of asset management strategies can be vastly improved by establishing a bedrock of fundamental knowledge across a team before any reliability improvement process is ever initiated. And it provides the steps on how to do it.
Does it annoy you that in spite of regularly performing Preventive Maintenance (PM) on your equipment it continues to breakdown? Some may call this insanity – Continuing to do the same thing over and over, expecting a different result. So what do you do? Maybe take a close look at your current PM Program.
There are known best practices which will not only enhance your PM program but also increase equipment reliability. Remember most work comes from PM and PdM and then it must be planned correctly, scheduled with production, executed to schedule and to specifications. If this occurs you will be seeing the results.

It provides examples of applying FMECA to analyze components and recommends corrective actions to address high risks.
Demystifying the Common Misconceptions about Reliability Centered Maintenance...Nancy Regan
This presentation demystifies the common misconceptions about Reliability Centered Maintenance (RCM). Sadly, it is often wrongly believed that RCM takes too long to perform, or it is too expensive, or it is too complicated. This just isn’t so. These misunderstandings about RCM stem from key misconceptions of the RCM process: 1. RCM seeks to analyze every Failure Mode; 2. RCM is too time and resource intensive; 3. RCM is just about deriving proactive maintenance; 4. RCM, Failure Modes and Effects Analysis (FMEA), and Failure Modes, Effects, and Criticality Analysis (FMECA) are independent process; 5. Condition Based Maintenance (CBM) and RCM are independent processes; 6. Reading a book or attending an introductory course provides the expertise required to implement RCM. This presentation debunks these misconceptions and sets forth just how robust, powerful, and uncomplicated the RCM process really is.
We all want to support the accomplishment of safe and trouble-free products and processes. Failure Mode and Effects Analysis has the potential to be a powerful reliability tool to reduce product design and manufacturing risk in a cost effective manner. With shorter product development times, tighter budgets and intense global competition, Design for Reliability tools such as FMEA must be applied correctly. Yet in practice, FMEA does not always achieve the expected results. Why is it that some companies have outstanding success in their FMEA application and others do not? What is the difference between well done and poorly done FMEAs? What are the essential elements of an effective FMEA process? These questions and more are answered in these three new short courses on FMEA.
This document provides an overview of Failure Mode and Effects Analysis (FMEA). FMEA is a systematic method used to evaluate potential failure modes in a design, process or service and their causes and effects. It involves analyzing potential failures, their likelihood and severity, and identifying actions to address potential failures with high risk priority numbers. The document defines key terms in FMEA like severity, occurrence, detection and risk priority number. It also outlines the FMEA process, including steps to identify potential failure modes, effects, causes, current controls and priority actions.
The document discusses Failure Mode and Effects Analysis (FMEA), a systematic method for evaluating processes and identifying risks and failures. It describes the FMEA steps which include selecting a process, assembling a team, identifying potential failures and causes, analyzing severity, occurrence, detection and calculating a risk priority number. The document also notes some limitations and reasons FMEAs may fail, such as not involving all team members or getting bogged down in details.
This document provides an evaluation of preventative technologies for Kangaroo Inc., a dental software company. It identifies the top risks as patching, outdated firewalls, BYOD, backup failures, and lack of change control. A failure modes and effects analysis identifies patching as a major risk due to staff turnover and system diversity. The outdated firewall lacks vendor support and regional offices have expired intrusion detection. Recommendations are provided to reduce residual risks through improved patching, new firewalls, BYOD policies, backup solutions, and change control procedures.

Reliability Centered Maintenance (RCM) is a proven, logical, sensible approach that helps companies improve reliability.
Yet most companies are not getting the return they expected. They see RCM as too much trouble for too little reward.
So that’s why we decided to publish this new report. Find out why RCM doesn’t work, what needs to change and how to put RCM to work at your company so it doesn’t become another Resource Consuming Monster.
The document provides an overview of Failure Mode and Effects Analysis (FMEA) as a tool to identify, analyze, and prevent potential product and process failures. It discusses the history and definitions of FMEA, the different types of FMEAs (system, design, process), how to conduct an FMEA including forming a team, terminology, scoring, and developing action plans to address high risks.
Reducing Product Development Risk with Reliability Engineering MethodsWilde Analysis Ltd.
Overview of how reliability engineering methodology and software tools can help companies manage risk during product development and improve performance.
Presented at the Interplas'2011 exhibition and conference at the NEC on 27th October 2011 by Mike McCarthy.
This presentation looks at how ‘Reliability Engineering’ tools and methods are used to reduce risk in a typical product development lifecycle involving both plastic and metallic components. These tools range in complexity from simple approaches to managing product reliability data to the application of sophisticated simulation methods on large systems with complex duty cycles. Three examples are:
- Failure Mode Effects (and Criticality) Analysis (FMECA) to identify, manage and reuse information on what could go wrong with a design or manufacturing process and how to avoid it
- Design of Experiments for optimising performance through a structured and efficient study of parameters that affect the product or manufacturing process (e.g. injection moulding)
- Accelerated Life Testing to identify potential long term failure modes of products released to market within a shortened development time.
We will explore how gathering enough of the right kind of data and applying it in an intelligent way can reduce risk, not only in plastic product design and manufacture, but also in managing the associated supply chain and in the ‘Whole Life Management’ of products (including warranties). Furthermore, we will show how ‘sparse’ data gathered from previous or similar products, such as field/warranty reports, engineering testing data and supplier data sheets, as well as FEA, CFD and injection moulding/extrusion simulation, can inform and positively influence new product design processes from concept stage onwards.
The document discusses applying Failure Mode and Effects Criticality Analysis (FMECA) to software engineering. It describes FMECA as a structured method to anticipate failures and their causes. The document outlines how FMECA was originally used in industries like aerospace and nuclear engineering but has expanded to other domains. It then discusses applying FMECA at different levels of a software project, from requirements to architecture to design to code. The document advocates an "enlightened approach" to using FMECA across all representations and abstractions of software.

Root Cause Analysis (RCA) is a structured process that identifies the underlying causes of undesirable events. It can be used for both single and multidisciplinary cases. The RCA process involves data collection, identifying the immediate causes and basic causes of failures, and determining where lack of control contributed. Common investigation techniques include STEP, FMEA, and fault tree analysis. Laboratory analysis of failed parts is also important for identifying causes like material defects, corrosion, or overloading. Identifying root causes allows corrective actions to be implemented to prevent future recurrence.
Root Cause Analysis (RCA) is a structured process that identifies the underlying causes of undesirable events. It can be used for both single and multidisciplinary cases. The RCA process involves data collection, identifying the immediate causes and basic causes of failures, and determining the lack of controls that allowed the failure to occur. Conducting detailed analysis of failed parts through methods like STEP, FMEA, and FTA allows investigators to identify issues like material defects, improper operation, or inadequate maintenance as the root causes of failures. Addressing these root causes helps improve equipment reliability and availability while reducing maintenance costs and downtime.

Investigation – Gathering evidence
Containment – Limit the damage by isolation and mitigation
Analysis – Reconstruct the incident. Who is responsible? How did they do it? When did it occur? Why did they do it?
Tracking – Document the incident and determine the source
Recovery – Mitigate the incident and apply lessons learned to reduce risk of recurrence
Triage
The term Triage is used within the medical community. Triage is the art of rapidly assessing the severity of the incident and following the right protocols, in the right order, to reduce the consequences of the incident and doing it all in the midst of crisis, when every second counts.
Different incidents require different responses – A Denial of Service attack (DOS) has to be addressed differently than a malware infection.
Establishing baselines can help identify unusual activity. The number of indicators to potential incidents are very high, so false positives are common.
Investigation
The Incident Scene – The Environment where potential evidence may exist
Principles of criminalistics apply
Identify the scene
Protect the Environment
Identify evidence and potential sources of evidence
Collect Evidence
Minimize the degree of contamination
General Guidelines
All general forensic and procedural procedures must be applied
Seizing digital evidence must not alter the evidence
Any person accessing original digital evidence must be trained
All activity relating to seizure, access, storage, or transfer of digital evidence must be fully documented, preserved, and available for review
While an individual is in possession of digital evidence, he or she is responsible for all actions
Any agency responsible for seizing, accessing, storing, or transferring digital evidence is responsible for compliance with these principles
Roles and Responsibilities
A solid foundation of knowledge and policy
A properly trained response team
Core areas must be represented
Chain of Custody
Tracks Evidence Handling
A formal, well-documented procedure MUST be followed – NO EXCEPTIONS
Locard’s Exchange Principle
When a crime is committed, the perpetrators leave something behind and take something with them.
Digital Forensics
Be Authentic
Be Accurate
Be Complete
Be Convincing
Be Admissible
Live Evidence
Data that is dynamic and exists in processes that disappear in a relatively short time frame once the system is powered down
Short Term Containment
The short term goal is to prevent more damage from occurring and provide time for additional analysis and mitigation. Isolate the system from the production network and create a backup cop.
The document discusses guidelines for conducting accident investigations. It describes preparing an investigation team, gathering at the accident scene, interviewing witnesses, examining the location and factors involved, determining causes, and developing corrective actions. The goal is to understand what happened to prevent future accidents and complete required reporting. A quiz at the end tests comprehension of proper investigation procedures.

The document discusses guidelines for investigating incidents in an organization. It covers:
1. The importance of investigating all incidents, including near misses, to identify root causes and prevent recurrences.
2. Organizational preparation for incidents, including communication plans, training employees, and determining investigation procedures.
3. Guidelines for investigations, including involving multiple perspectives, collecting data through interviews and documentation, and focusing on system-level causes rather than individual blame.
This document outlines the steps of the Why-Why root cause analysis (RCA) process used in total productive maintenance (TPM). It begins by explaining that RCA identifies the underlying causes of losses by asking successive "why" questions to determine root causes. The 6 steps are: 1) identify the problem, 2) understand the ideal situation, 3) identify the phenomenon using 5Ws and 1H, 4) develop a cause tree by asking "why" for each factor, 5) implement countermeasures for the root causes, and 6) standardize the improvements. Examples are provided for each step to illustrate how to apply the Why-Why analysis to identify root causes of equipment failures or process issues.

Genetic libraries allow researchers to study genes and proteins from organisms. There are two main types of genetic libraries: genomic libraries and cDNA libraries. To build a genomic library, genomic DNA is extracted from an organism and cleaved into fragments using restriction enzymes. These fragments are then inserted into plasmids which are introduced into bacteria, allowing amplification of the complete genome. A cDNA library focuses only on expressed genes. mRNA is extracted and converted to cDNA, then inserted into lambda phages which infect bacteria for replication. The library can then be screened using probes to isolate specific DNA fragments of interest.
Hepatitis A is caused by the hepatitis A virus (HAV), which has a single-stranded RNA genome surrounded by an icosahedral capsid. The virus is primarily spread when an uninfected person ingests food or water contaminated with the feces of an infected person. There is no specific treatment for hepatitis A, but improved sanitation, food safety, and immunization are effective ways to prevent the disease.
Bacillus thuringiensis is a bacterium that produces proteins toxic to certain insects. The first Bt corn was registered with the EPA in 1995. Bt corn provides over 99% control of European corn borers through Cry proteins in plant tissues that form pores in the insect's gut, causing paralysis and death.
1) The document discusses developing a machine-centered preventative maintenance program that optimizes machine health rather than focusing on individual technologies or minimizing costs.
2) It recommends taking a systematic approach of first identifying possible machine failures, determining which are most significant, trying to avoid failures, getting early warnings of failures that can't be avoided, tailoring tests to detect those warnings, and collecting all machine health data at key decision points.
3) This machine-centered approach aims to better assess overall machine health, catch issues earlier, defer unnecessary overhauls, and improve failure management compared to traditional technology-centered programs.
The document outlines a 6 step motor management plan to minimize costs, maintain reliability, and receive early warnings of failures. The steps include: 1) creating a motor inventory and tracking program, 2) developing repair/replace guidelines, 3) preparing a spares inventory, 4) establishing purchasing specifications, 5) developing repair specifications, and 6) implementing planned maintenance. The overall goals are to reduce energy costs through proper sizing and efficiencies, maintain uptime, and detect potential issues before failures occur.
This document outlines a six step process to take a machine-centered approach to machinery healthcare:
1. Identify possible failure modes of the machine.
2. Determine which failures are most significant based on frequency and consequences.
3. Figure out ways to avoid failures through adjustments, lubrication, or preventative replacements.
4. For failures that can't be avoided, identify ways to get early warnings through process parameters, inspections, or technology.
5. Tailor a suite of tests to monitor for early warnings of significant failures.
6. Collect all monitoring information at a single decision point to determine if maintenance is needed.
Taking this approach optimizes the health of each machine
Mark is the maintenance manager who wants to implement a CMMS to digitize their maintenance processes but knows some employees may resist change. The document outlines the three dimensions of change that Mark needs to consider to maximize success which are getting the organizational culture, individual employees, and infrastructure supporting the new system all on board with the transition. It provides advice on assessing where people are in accepting change and guidance on moving them along the adoption curve.
