FRACAS: From Data Collecting to Problem Solving



Testing, data collecting and data analysis are probably the three major daily tasks for most reliability engineers. How to utilize the modern database and Internet technology to manage the testing, data collecting and problem solving process across multiple departments is a challenging issue that many organizations are facing. XFRACAS, a web-based Failure Reporting, Analysis and Corrective Action System (FRACAS) by ReliaSoft, provides an organization-wide platform that connects all the reliability-related management and analysis activities together. In this article, we will briefly discuss the history and the role of the FRACAS in a reliability program.

What is FRACAS?

FRACAS stands for Failure Reporting, Analysis and Corrective Action System. The FRACAS process originated from the defense and aerospace industries in the 1970s. It was an essential element in the early and sustained achievement of the reliability and maintainability potential inherent in military systems, equipment and associated software. Since the late 1970s and through the 1980s, major players in defense, aerospace, automotive and telecommunications worldwide invested millions of dollars to develop and support in-house FRACAS-related software. In 1985, the MIL-STD-2155 standard was created with the intent to standardize the scope, definition and implementation of the FRACAS process.

The FRACAS method is used in many applications, such as safety/risk reduction systems, process control systems and incident reporting systems. It provides a disciplined and aggressive closed-loop process for solving issues at the design, development, production and deployment stages. The fundamental tasks include:

As an example, the following screenshots show portions of the failure/incident reporting page from ReliaSoft’s XFRACAS software tool. This web-based interface is highly configurable. Organizations can add, remove and define fields based on their own needs.

What can FRACAS do?

The FRACAS method promotes the reliability of a product or process by establishing a formal process followed by the entire organization. It gives the following benefits:

The FRACAS method also promotes reliability improvement throughout the life cycle of a product. It can be used and applied during:

With the advancement of computer technology, FRACAS has evolved from a paper-based single-person tool to a web-based multiple-user system. It is also no longer limited to simple failure reporting, analysis and correction, because it can be integrated with formal problem resolution methods such as the "8 Disciplines" (8D) approach.

There are also other standard methodologies such as 6-Sigma’s 5-step DMAIC methodology, and a variety of 4-step methods.


As an example, the following picture shows how the 8D methodology can be implemented in ReliaSoft’s XFRACAS tool.

The figure shows the Problem Report interface, which provides a flexible framework for team-based problem resolution. With this approach, you can assign multiple incident reports to a single problem. This enables you to resolve the underlying problem, which addresses all related incidents and improves the design and/or process to prevent similar problems from occurring in the future. The Problem Report interface can be customized to support any problem resolution methodology.

XFRACAS can also be configured to capture the details of failure analysis investigations. This gives a complete record of your organization's response to a particular failure. ReliaSoft's Weibull++ and RGA software applications are integrated in XFRACAS, enabling you to easily use the failure data to perform reliability analysis.

XFRACAS also provides database features such as querying, tracking and reporting. You can easily track the progress of projects and uncover bottleneck problems, as well as track the status of each team member's current tasks. In addition to the system’s powerful closed-loop action management capabilities (automated e-mail notifications, easily generated status reports, etc.), XFRACAS allows you to create checklists, link or attach related documents, query the "knowledge base" of past issues/solutions and identify stages (gates) that require formal review/approval.

How to implement FRACAS?

There are different ways FRACAS can be applied. Each application might appear to be different, but at the core, they are similar. Here are some of the best practices for implementing a FRACAS system:

FRACAS Lessons Learned: Avoid Failed Implementations

Although FRACAS is a useful tool and should be used in every organization, it involves a change in the company culture and many different departments in an organization. Some of the lessons learned are:

IT Issues: Many organizations already have systems in place that have some functions related to FRACAS. However, most pre-existing systems were not designed for solving reliability- and quality-related issues and so do not provide a closed-loop problem resolution process. For example, it is sometimes not easy to convince IT departments to implement a full FRACAS system due to the inherent resistance, security and resource concerns.

Organization Issues: During the FRACAS process, various functional groups can be involved. In many cases, the interactions of these groups can be very complex and competitive. For example, one group may assign an incident or action to another group, with the latter group assigning the incident or action back to the original group or to another group, making the resolution of the incident an "infinite" loop.

Undefined Goals: It is crucial that goals and expectations are clearly defined before embarking on a FRACAS system implementation. Any constraints (cost, data availability, etc.) should be analyzed in order to determine how thorough the FRACAS process should be.

It is typical for organizations to evolve an internally-developed FRACAS system over time as their needs and sophistication grows. It usually takes more than 2 – 4 years to see the benefits of a FRACAS system. Here are some suggestions to help overcome resistance during the process:


In this article, we discussed the benefits of the closed-loop incident resolution process of FRACAS. Using ReliaSoft’s XFRACAS tool, you can set up a formal process for reporting, analyzing and resolving reliability-related issues during the product life cycle. XFRACAS now is part of ReliaSoft’s Synthesis Platform. It can seamlessly work with ReliaSoft’s other applications such as Xfmea, Weibull++ and RGA.

Correctly using FRACAS will benefit the entire origination by speeding up the development process, reducing waste, accumulating useful information and making final products more reliable. However, implementing a FRACAS system involves multiple functional departments and, sometimes, a need to change the company’s culture. It may take years and support from management to make the implementation successful.
