Cause-and-effect analysis

The guidance for tliis element covers responsibilities and authorities, determination of the significance of a quality (ESH/PSM) related problem, root cause investigation, cause-and-effect analysis, preventive actions and additional controls, and change documentation. For ESH/PSM, this element might be interpreted as covering both potential hazards as well as actual problems. 

Cause-and-effect analysis reveals that steam purity and quality are both reduced by the degree of carryover taking place in a boiler, and carryover is itself a function of the effectiveness of steam-water separation. In turn, the mechanics of separation are a function of three areas, each with its own variables ...

A cause and effect diagram (sometimes known as the Ishikawa"" or the fishbone diagram"") represents the relationships between a given effect and its potential causes. The cause and effect analysis relates the interactions among the factors affecting a process.

From the cause and effect analysis, it is observable that the dust does a harmful function to the filter, which is clogging it. Here lies the contradiction. The filter is needed to perform a useful function of trapping the dust, but the dust does a harmful function by clogging the filter, which results in lower suction power. Hence, the problem will be modeled as an engineering contradiction and the contradiction matrix will be used to device a solution. 

Cause and effect analysis is useful in any kind of process capability analysis, not just as the result of attributes inspection and Pareto analysis. The focus of cause and effect analysis is on attacking a problem rather than on fixing blame. Once a nonconformity has been isolated for further study, attention shifts to analyzing how the deviation from specifications was caused. Sometimes the reason is obvious sometimes a considerable amount of investigation is required to uncover the cause or causes. The Japanese have developed and used cause and effect analysis, and the resulting diagram, as a formal structure for uncovering problem areas. The steps in a cause and effect analysis are (Ishikawa 1982,18) ...

Many studies also have been conducted on environmental costing in an organization or a supply chain (Roy et al. 2009). As Nikolopoulou and lerapetritou (2012) have mentioned, there are many systematic methods which can be used as environmental performance indicators of product and process such as product life cycle assessment (LCA) and minimal environmental impact. Letmathe and Boost (2000) proposed cause and effect analysis to assign environmental cost. Be Beer and Friend (2006) considered 5 types of costs including internal and external costs and also regarded environmental revenues. 

First, one needs to identify the unit with the help of an ID so that it can be pinpointed and later can be referred. The functions of the element are listed. It is important to list all functions. Then, based on operational mode, various failure modes are listed, as discussed in earlier clauses. For each case, cause and effect analysis is done to discover severity, occurrence, likelihood, etc. Since all these have been discussed in earlier clauses, and explained in the figure, they are not repeated. One important thing to note here is the Class column. It sometimes shows YC or C or N, etc. YC is for criticality and significance. Normally, criticality matrix is chosen and critical characteristics are confirmed. In DFMEA/DFMECA when criticality is present, then PFMEA/PFMECA needs to be carried out for verification. If in PFMEA/ PFMECA the same is present, then a suitable control plan shall be developed to eliminate the criticality as far as possible. Similarly, in some cases N is placed in class column to indicate noise, meaning that it is a risk that should be mitigated, but is largely out of the control of the development team, whereas C stands for controllable.

The system is not complex. It is easy to learn and use. The Five Why system has been related to the Ishikawa Fishbone Diagram, a cause-and-effect analysis system.

This method, which is also called a cause and effect analysis or the Ishikawa analysis (Black and Kohser 2008, Hensey 1993, Rose 2005), provides a systematic way to thoroughly identify widely-varying possible causes of a problem. Once again, assemble a diverse group, provide background, pose the problem, and construct the fishbone diagram. 

Cause- and-effect analysis Cause and effect analysis is a qualitative method to identify possible causes of an unwanted event or problem. 

Cause and effect analysis is a technique that can be used in the root cause analysis. Thereby this technique uses techniques like brainstorming, sometimes tree diagrams and mostly a fishbone diagram to structure a list of causes of a specific effect.

Cause and effect analysis is another tool that can be used to identify the causes of problems with a view to removing or avoiding the causes. It seeks to separate symptoms from causes by a process of progressive questioning - sometimes known as Asking why - five times (see box). 

These activities are the basis for the derivation of the key performance indicators. Cause and effect analysis can aid in their identification. 

MORT/ Mini-MORT Use when there is a shortage of experts to ask the right questions and whenever the problem is a recurring one. Helpful in solving programmatic problems Can be used with limited prior training. Provides a list of questions for specific control and management factors May only identify area of cause, not specific causes If this process fails to identify problem areas, seek additional help or use cause and-effect analysis...
