Solutions for most problems that Qualimations handles are derived and solved using analytical methods. These solutions prove to be very useful and provide excellent insight into the behaviour of many systems. DOE allows for multiple input factors to be manipulated determining their effect on a desired output (response). By manipulating multiple inputs at the same time, DOE can identify important interactions that may be missed when experimenting with one factor at a time. All possible combinations can be investigated using the DOE apprach. Qualimation has several samples of successful implementation of the DOE tool in the quality improvement program. We also suggest you when not to use these methods and to start resorting to other means of analysis.

Design of experiments is a very powerful tool that can be utilized in all manufacturing/service industries. Quality managers who encourage DOE use will greatly increase their chances for making breakthrough improvements in product quality and process efficiency.

Design of Experiments (DOE) techniques enable designers to determine simultaneously the individual and interactive effects of many factors that could affect the output results in any design. DOE also provides a full insight of interaction between design elements; therefore, helping turn any standard design into a robust one.

In brief, DOE helps to pin point the sensitive parts and sensitive areas in your designs that cause problems in Yield. Designers then are able to fix them and produce robust and higher yield designs prior going into production.

What is Designed Experiments ?

Every factor operates at different levels or stages during a process. These levels are either determined so that the process adds value to the product and hence there is a value associated with it. As an example, a flight management over booking could be set at two levels, one which takes low levels of risk and other which takes high risk. The factor here is risk, the levels are low and high. When you bake a cake, the factor are temperature and time in the oven, you could keep at high temperature or low temperature and this can be done at several levels of time. The objective in this experiment is to make a perfect cake. The factors that contribute value, like temperature and time are also the same factors that contribute to the issue or problem...  Read More

Warranty Analysis

Warranty Analysis focuses on predicting future warranty and maintenance cost of running the whole program. At Qualimation Tech we have developed methods that helps in early detection and correction of some of the warranty related problems also this Information is needed to perform root cause analysis on product failures. Since field failure forms as basis for FMEA, study of warranty is essential to the quality managment process. The Warranty information also forms as basis to feed subsystem and component level reliability information...  Read More
