Seven Basic Quality tools documents
Definition of Quality Management -- it is a method for ensuring that all the activities necessary to design, develop and implement a product or service are effective and efficient with respect to the system and its performance. It is also a principle set by the company to endure the continuous advocacy of quality services and products, or the further improvement of it.

IMPROVING CUSTOMER SATISFACTION IN THE SERVICE INDUSTRY
USING FAILURE MODE & EFFECTS ANALYSIS
Repetitive failures cost companies millions of dollars in redesign costs, liabilities, and transaction costs. However, by far the most serious cost of these failures is the lost business that results from customer defection. For service companies, the task of providing error-free services is even more challenging because their intangible nature renders subjective perceptions of quality. Equally troublesome is the uncontrollable element of customer participation in the service process because production and consumption occur as a simultaneous process. Despite these challenges however, service quality and customer satisfaction are closely related constructs. When service providers continuously strive to develop error-free processes, customer satisfaction is sure to follow.
What is FMEA?
What steps should be taken to conduct a FMEA?
Once a service provider decides FMEA is the right choice, the following ten steps can be used to guide the implementation process:
- Select a service process to be analyzed
- Define responsibility (team, engineers, designers, developers etc)
- Flow-chart the process
- List and describe all failure modes at each step in the process
- Perform a criticality assessment by determining the risk level for each fault by failure probability or severity of failure
- Rank the faults in terms of priority
- Design changes to reduce the risk of the highest priority failure modes
- Specify outcome measures and criteria to determine the success of the changes
- Specify a time frame
- Implement the changes and evaluate
Design changes should continue until all possible causes of failure have been reduced or eliminated. As mentioned earlier, while FMEA can technically be performed at any stage, ideally it is performed at the process design stage. This way, potential problems can be identified and prevented before the process is put in place.
What potential rewards can FMEA provide?
Service companies who frequently conduct FMEA’s and evaluate their success typically experience:
- Minimized customer defection/increased customer satisfaction
- Increased consistency in service quality
- Reduction of costly design changes
- Reduced transaction costs/increased profits
- Reduced liability
What are the advantages of using FMEA versus other methods?
FMEA is differentiated over other types of failure analysis methods in that it is particularly adept at:
- Identifying cause and effect of known and potential failures before they occur
- Providing documentation of failures which can be tracked over time
- Making accountability easier to pinpoint
- Facilitating continuous improvement
- Creating a common language that can be easily understood by both technical and non-technical people in the organization
FMEA in practice: Six Sigma Qualtec
An investment management firm providing a transactional web site to 401(K) plan participants received numerous complaints from clients who could not make informed investment decisions because the web site was not being updated in a timely manner. Mutual Fund Asset Value updates, for example, were late 35% of the time. The firm identified non-value added steps in their web site update process, using process maps, FMEA, measurement system analysis, ANOVA, multi-variable analysis and process control systems. The non-value added steps were eliminated, and manual reconciliation was automated. Eventually, the firm outsourced a standardized process to a third party web administrator, which yielded $100,000 in net savings. At-risk revenue retained through client satisfaction was $5 million.
