High-quality reliability reports are central to the reliability manager’s success in ensuring the optimal performance of machinery and equipment. Reliability reports are not mere documents that, when accomplished, are filed and never to be used again.
These reports must serve as the basis of decision-making and strategizing that will bring every organization closer to its bottom line. Thus, prioritizing quality in reliability reports ensures the accuracy of data and a better chance of achieving reliability goals.
What is a Reliability Report?
A reliability report is a document that contains detailed information on machine or equipment performance, maintenance, operational status, and other reliability-related data. The information in a reliability report will vary depending on the type of machine or asset, operations, and industry.
Reliability Report Components & Purposes for Reliability Manager
Below are the common components of high-quality reliability reports and their purposes:
Failure Data
This includes all failures experienced by the machine or equipment. Data must also include details about the failures such as frequency, causes, impacts, corrective and preventive actions taken, etc. Failure data helps reliability managers understand machine failure patterns and root causes.
Root Cause Analysis
This provides information on the analysis of root causes of failures and their results. The analytical techniques used often include Failure Mode and Effects Analysis (FMEA) or Root Cause Failure Analysis (RCFA). Analyzing root causes helps reliability managers address underlying issues of machine failures, managing these directly and not just their symptoms.

Downtime Data
This includes all planned and unplanned downtime experienced by the machine and equipment. Reliability Managers must analyze the amount, frequency, and causes of downtime, to identify effective methods to reduce it.
Maintenance Records
This includes information on all maintenance activities performed on a machine or equipment. Tracking and recording all corrective and preventive maintenance helps reliability managers evaluate current maintenance strategies and identify areas of improvement.
Performance Analysis
This provides information on key performance indicators (KPIs) such as Mean Time Between Failures (MTBF), Mean Time to Repair (MTTR), Overall Equipment Effectiveness (OEE), and similar metrics of equipment performance.
Determining and analyzing these metrics is a valuable way for reliability managers to quantitatively measure equipment reliability, helping gauge the success and progress of reliability efforts.
Condition Monitoring Data
This includes data from predictive tools and techniques such as vibration analysis, thermographic, and oil analysis. Collecting and analyzing these data helps reliability managers predict and prevent the occurrence of failures.
Compliance and Safety Records
This provides information on compliance and safety, including safety-related incidents, instances of non-compliance to standards, and violations of regulations. These records also provide the details of the corrective actions performed to address the safety and compliance issues.
Reliability managers refer to these records to improve and maintain the safety and compliance with the facilities and operations.
Recommendations and Action Plans
This includes suggestions and proposals for continuous improvement of reliability. These recommendations must be based on data and analysis presented in the reliability report.
Reliability managers refer to previous recommendations and action plans to keep driving the pursuit of reliability forward.
Data Quality in Reliability Reports
Equipment reliability can only be successfully achieved through the quality of the information in reliability reports. Thus, reliability managers must ensure that only the highest quality data are collected for effective reliability decisions and strategies.
To do this requires understanding the following characteristics of data quality:
1. Accuracy
Data must be correct and free of errors. Having high-accuracy data ensures that the reliability reports provide insights and conclusions that are valid and trustworthy.
2. Completeness
Data must include all the information necessary for correct analysis and decision-making. Complete data ensures a more comprehensive understanding of equipment, and consequently, more effective reliability measures implemented.
3. Consistency
Data must be consistent across different sources and periods. Otherwise, reliability reports will only result in confusion and misinterpretation. Consistent data is critical for accurate trend analysis and comparison.
4. Integrity
Data must be protected from unauthorized or untracked modification. High data integrity ensures that accurate and reliable data are maintained over time, promoting continuous reliability improvement.
5. Reasonability
Data must be logical, plausible, and make sense contextually. Otherwise, data becomes misleading and questionable. Reasonable data equals accurate, actionable, and trustworthy information that ultimately results in effective maintenance and optimized equipment performance.
6. Timeliness
Data must be up-to-date and easy to access whenever needed. Timely data provides current information necessary for relevant decisions, planning, and management of reliability strategies.
7. Uniqueness
Data must be distinct, non-redundant, and unduplicated. The occurrence of duplicates and redundancies may point to inefficient or wasteful reliability measures or activities. Unique data provide accurate and clear information, promoting effective decision-making and optimum reliability results.
8. Validity
Data must appropriately represent the concept or measurement it is intended to reflect. Valid data is critical for accurate insights into the reliability, performance, and maintenance needs of equipment.
Challenges to Data Quality
Poor data quality in reliability reports, and consequently, reduced reliability, results from improper data collection, storage, and analysis.
Poor data quality can be a result of:
Data Volume - Large amounts of data require more time, labor, and other resources to collect and analyze. These resource constraints result in rushed, inaccurate, or incomplete data collection and missing or inappropriate tools to analyze data.
Lack of Standardization - Using different tools and methods to collect and analyze data results on varying levels of accuracy. Varied data formats, metric terms, units of measurement, and data recording methods also show a lack of standardization that results in inconsistent and poor-quality data.
Processing Delays - Delayed data entry and slow data processing reduce the timeliness of information and, thus, the effectiveness of reliability measures. Data processing delays can be a result of large data volumes and inadequate resources to process them.
Data Security - Preventing unauthorized personnel access to data requires complex steps and strategies to maintain data integrity. In addition, data security threats can also come from software bugs, hardware failures, or cyber-attacks that can corrupt critical data.
Ineffective Integration - Data can come from multiple sources within and even outside the organization. Integrating data can be challenging because of varying data sources such as sensors, manual logs, management software systems, lab test results, etc. Ineffective integration results in incomplete, outdated, or redundant information.
