Abstract

In our days, with the constant surge of global competition and the globalization of markets, the success of project implementation and management depends largely from the organization’s business performance. These affairs have brought many changes in terms of economic, technological and marketing basis. The investment and implementation of a new technology requires a serious effort from the organization because most of the times, deals with factors such as risk, complexity, innovation and lacking of resources. All these factors, among others, can be considered as extremely important challenges from the special workforce of the companies, that’s why it is very common for them to set up and implement new special projects in order to face them as effective and as quick as possible .

Based on that, identifying and alleviate project risks are very important steps in achieving successful project management and therefore successful projects programs and portfolios. Nevertheless, methods and tools for risk assessment and risk management that have been developed and implemented to increase the possibilities of project success are not yet extensive or easily adopted . However, one of the most well-known and widespread methods is the method called Failure Modes and Effects Analysis (FMEA). FMEA as Project Management tool allows to:

•Evaluate a process to identify where and how it might fail

•Identify the failure causes

•Assess the relative impact of different failures

•Anticipate potential problems before they occur

On top of that, it is generally accepted that when FMEA is used as a Project Risk Management tool, it can be labeled also as project risk FMEA or RFMEA. So, the RFMEA technique is not just another way of analyzing project risks but helps focus the risk contingency planning, required early in the project on critical risks . Finally, this method is highlighted as crucial and important in the engineering management community.

Big Idea

What is FMEA - Evolution of FMEA

Failure mode and effects analysis can be characterized as an easy to implement and yet powerful pro-active engineering quality method that helps to identify and counter the weak points in the early conception phase of products and processes . In other words, FMEA is a systematic method / predictive maintenance method which allows to evaluate a process to identify where and how it might fail, identify and ranking the risks associated with various product (or process) failure modes (both existing and potential), prioritizing them for remedial action, acting on the highest ranked items, revaluating those items and returning back to the prioritizing step in a constant loop until marginal returns set in. .

FMEA is trying to anticipate potential problems before they occur, so it can be said that, from a time perspective FMEA is essential in the earliest development phases and thus, an early and accurate implementation of the method can be crucial for reducing the corrective actions as well eliminating the cost of a non-compliance identification. The measures that are taken into consideration when FMEA is being implemented is: the probability of failure occurrence (O), the severity of the failure (S) and finally the capacity to detect the failure before it occurs – detection (D) . . The multiplication of these measures generates the RPN (RPN = Occurrence * Severity * Detection). The special and professional workforce that will implement the FMEA consists of a multidisciplinary team of people from different educational backgrounds and areas (design, management, engineering, manufacturing) skilled with specific product / process know how.

The first application of FMEA dates back to the end of 1940s when the US Army used it in the aeronautic sector in order to solve safety and reliability problems in the production and design phases. After this, NASA continued the implementation of FMEA in the early 1960s through the Apollo Program and some years later, FMEA adopted by the automotive industry and specifically from Citroen and Peugeot. In 1993 AIAG incorporates FMEA into the QS9000 and since then, this technique is usefulness for all organizations.

FMEA can be divided in sub methods throughout the product development phases. For example, DFMEA (Design Failure Mode & Effects Analysis) is used to create new products and analyze product designs before they are released to production. It focuses on potential failures and problems that can be occurred through the design process. On top of that, PFMEA (Process Failure Mode & Effects Analysis) is used to identify and examine risk in process changes and problems with the function of a product caused by the problem in the process. SFMEA (Software Failure Mode & Effects Analysis) focuses on identifying the causes and consequences of possible software failure modes. Last but not least, RFMEA (Risk Failure Mode & Effects Analysis) focuses on the risk contingency planning required early in the project on critical risks. RFMEA will be analyzed in detail throughout the article.

Why FMEA?

It is generally accepted that, FMEA can bring a variety of benefits and positive results in the organizations. First of all, prevents problems and failures in the system, products or processes before they even occur, reduces greatly the costs, creates condition for processes durable to unexpected events as well as classifies actions and events based on priorities and seriousness.

Furthermore, FMEA is able to detect possible unidentified failures, find and document the main reasons behind failures and impacts and prepare a response plan with priorities, areas of responsibilities and frames.

Lastly, assigns the appropriate maintenance actions to uncharted problems and thus, records all the possible work of the maintenance staff.

In conclusion, the main advantages of FMEA can be summarized as:

• Early identification of failures and problems throughout all the stages

• Early improvements in the design and the product processes

• Important cost as well as risk reduction

• Assessing of the failures and their impact as well as finding mitigation solutions

FMEA as a Project Risk Managemnt Tool

The Project Management Institute (PMI) defines a project as a temporary endeavor undertaken to create a unique product, service or result. The temporary nature of projects indicates that a project has a definite beginning and end. The end is reached when the project’s objectives have been achieved or when the project is terminated because its objectives will not or cannot be met, or when the need for the project no longer exists .

As the main goal of a project is to generate an unknown product, it usually involves risk because the steps to achieve the proposed targets are now known by the people who are in charge of the project development. The concept of project risk is related to all the events or conditions that can generate positive or negative effects in at least one project objective. Risks can be classified as internal, when the project team can influence or control them, and external when the project team are unable to control and influence them .

The effective risk management implementation is an essential element of successful project management. Proper risk management can play a vital role to the mitigation on both known and unanticipated risks on projects of all kinds. Failure to perform effective risk management can cause projects to exceed budget, fall largely behind schedule, miss critical performance targets or even creating a combination of all these drawbacks. So, having an effective method to plan for and manage project risks that is easy for the project team to understand, adopt, test, use and finally apply is very critical. Finally, as projects increase in complexity and size, taking a multidisciplinary approach to project management requires, as it makes sense, a proper attention to risk management .

A Guide to the Project Management Body of Knowledge PMBOK® Guide 2017, defines the risk management process, as being comprised of six main steps: risk management planning, risk identification, qualitative risk analysis, quantitative risk analysis, risk response planning and risk monitoring and control . .

The probability attribute of a risk event has been defined with various terms such as, ‘’probability’’, ‘’likelihood’’, ‘’probability of occurrence’’ among others. Ratings and scales used for these range from low, medium and high, 1 to 10 or 0 to 1 or some other linear and non scale. Nevertheless, these terms and scales are all correct, inconsistent use and terminology creates confusion most of the times . .

Risk analysis and risk management techniques include expert interviews, expected monetary value, and response matrices, along with more advanced techniques for risk analysis such as Monte – Carlo method. One risk management technique is being implemented by multiplying probability of the risk occurring with the expected impact of the risk. This method brings as a result the evaluation for each risk. In terms of this environment, the method of using the risk probability multiplied by the risk impact value is moving one step forward and expands by also multiplying a detection value for each risk . As it becomes obvious, by multiplying these three values of likelihood of occurrence (or probability), severity (or impact), and detection it is like implement the familiar format of the Failure Mode and Effects Analysis – FMEA. In the method of applying the FMEA format to project risk management, it is defined as mentioned earlier as risk FMEA or shortly RFMEA. This sub method of FMEA as an advanced format is capable on capturing project risks in every possible organization in high technology environments.

As stated above, the standard FMEA process evaluates failure modes for occurrence (O), severity (S) and detection (D). The multiplication of these values leads to what is known as the risk priority number (RPN). In using the RFMEA approach, there are a few required modifications in relation to the standard FMEA format. Specifically, the project RFMEA is a tool to identify, quantify and remove or reduce risks in a project environment against the classical product’s aspects as identified in the FMEA. The RFMEA is used in connection with the developed FMEAs for product design, process development and service deployment . The application and method for both FMEA and RFMEA are analyzed in detail in the next chapter of the article.

Finally, the largest aberration from the standard FMEA approach is the definition used for detection attribute. In the standard method, the highest detection value means that the organization has no detection capability available for the fault / problem, while a low detection number means that the organization has a way to detect the fault before it appears. On the other hand, regarding the RFMEA, the detection techniques are defined as, ‘’ the ability to detect the risk event with enough time to plan for a contingency and act upon the risk’’. So, if the responsible team can not be reasonably guaranteed that the risk can be detected either because is very difficult to identify it or because it has subtle symptoms, the detection number has to be assigned as a 10 (value that means that there is no detection method available or known that will provide an alert with enough time to plan for a contingency) at the initial plan .

Application

How to use FMEA?

The first and most important task of FMEA team is to collect information about the project or process that should be fully identified and implementation of activities and processes carefully be surveyed. On top of that, all of potential risks such as environment, equipment, materials, human and etc. should be taken into consideration. In order to collect accurate, useful and comprehensive information about the investigated project, the responsible team can get help through interviews or brainstorming sessions with informed, experienced and skilled people, practitioners, workshop and warehouse employees as well as check documents, operation standards and requirements of the equipment/workplace [4]. The process of FMEA consists of 5 different steps:

- Step 1: Define Scope & Topic: In this step a process has to be selected for evaluation. When evaluating with FMEA, works better when the processes have not too many sub-processes. In which case, it would be recommended to divide the process up.

- Step 2: Assemble a multi-disciplinary team of experts. Everyone involved in any part of the process needs to be included. Include operators, customers and suppliers.

- Step 3: Chart the process, create a detailed flow chart of the current process.

- Step 4: Make HAZARD Analysis (Table 1). Identify each of the potential failures that may occur at each step of the process and classify all failure modes into the risk priority number (RPN). Determine focus areas based on the probability, severity and occurrence of the failure.

Table 1: Hazard Analysis	Steps in Process	Failure Modes	Failure Causes	Failure Effects	Likelihood of occurence (1-10)	Likelihood of detection (1-10)	Severity (1-10)	Risk Priority Number (RPN)	Actions to reduce occurence of failure

Step 2
Step 3

- Step 5: Actions and measures. Identify how can you prevent the highest issues from happening. Failure modes with higher RPNs are the ones that should be addressed first. On the other hand, the ones with the lower RPNs will likely not affect the overall process much, so they should be at the bottom of the priority list.

Benefits of RFMEA

First and foremost, it has to be mentioned that, there have been tangible and intangible benefits realized from the RFMEA method. In terms of tangible benefits, time spent doing up-front risk contingency planning is reduced. Also, the RFMEA gives the team a better method for determining which risk planning can be postponed. That means, team is having more time to focus on the most critical risks, so the risk response plans are improved. Moreover, the detection value provides another benefit over just using the risk score by aiding the discovery of new detection methods for risk symptoms. Regarding now the intangible benefits, enhanced organizational learning is a critical benefit of RFMEA. Last but not least, if the team is able to detect a known risk with enough time to plan the contingency at a latter date, then this reduces the early planning time and so the team frustration. This case is true, especially in complicated and changing project environments .

Finally, the RFMEA is an advanced risk tool that is simple and intuitive. It is based on the standard FMEA technique, modified especially for Project Risk Management. With some minor modifications to a standard FMEA format, the RFMEA provides increased value to the risk management process. RFMEA is based on evaluating both the risk score and the RPN value to detect the critical risks that require immediate risk response planning. In terms of a proper utilization, RFMEA can greatly reduce risks on a project, create team ownership in risk planning and act as a resource for future projects in terms of knowledge, lessons and risk management . .

Limitations

For all its benefits in Project Management, FMEA does have a number of limitations. This method has become integral to any production process in any organization. It is widely considered as an improvement over traditional risk analysis and management, which treats each potential failure and problem in isolation. However, it is still not dogmatic. It remains as an assessment tool, not one that is designed to eliminate problems. The best implementation of FMEA can be achieved with the combination of other tools to see the control plans through.

So, the main limitations of the method can be summarized as, the FMEA prioritizes and does not act. Moreover, it is only as good as the professional team behind it, issues behind team members’ knowledge are not likely to be detected or resolved and that contributes to unknowns – unknows results. FMEA is taking on too large scope and not getting into the details. Also, is confusing rout cause and failure mode and does not customizing rating scales. Finally, sometimes it can be characterized as optimism bias regarding the project management.

Lastly, the main disadvantages of FMEA can be summarized as:

• It is a time-consuming process

• If a failure mode is omitted, then the respective risk is underestimated

• FMEA does not consider the correlation between failures
