Root cause defined

Scenario A description of the events that result in an accident or incident. The description should contain information relevant to defining the root causes. 

It helps to define two terms to understand the hierarchy of sequencing for the occurrences that make up an incident. The most widely accepted terms are causal factor and root cause ... 

The company will learn that reporting and investigating near misses will enhance overall business performance, particularly because the near misses of a safety incident or environmental release have the same root causes as incidents that detract from quality and productivity. Safety personnel can assist in defining an appropriate near-miss reporting culture. All managers intuitively understand the return on investment from preventing incidents. The effort pays for itself directly through improvements in productivity. 

Initial work is focused on what happened. Determination of root causes is important to prevent recurrence of the incident, but the initial focus of the investigation team is to define what happened. 

These two results are clearly different, while they should be equal. The root cause of the problem is that the exchange process is defined between the same nuclei those are coupled to each other and the higher order components of the coupling cannot be neglected any more despite the weak coupling.18... 

A root cause is a cause that would prevent recurrence of this and similar occurrences. The root cause does not apply to this occurrence only, but has generic implications to a broad group of possible occurrences.. . . [Tjhere may be a series of causes that can be identified, one leading to another. Each series should be pursued until the fundamental, correctable cause has been defined. 

Set timetable for improvement 2. Create multidisciplinary team to address the issue 3. Review the literature and/or published standards 4. Define quality indicators 5. Analyze baseline data 6. Review current practices 7. Perform root cause analysis 8. Create action plan for change... 

The outcome of the PQ may indicate that there are areas of weakness in the design or implementation of the application, in particular if high levels of design changes or functional failures are observed within a localized area. In such instances, it will be necessary to reconsider the adequacy of the OQ, and further testing may be required to determine the root cause of the failures. The outcome of the PQ shall further define the need to extend the PQ duration. 

However, such problem solving requires a carefully structured process to ensure that root causes are identified and proposed solutions are verified. Juran s project-by-project quality improvement process provides detailed guidelines that have been widely adopted and integrated into current team problem-solving methodology. The methodology outlines distinct steps for (1) carefully defining the problem,... 

Subgroups are defined to further distinguish between the root cause problems in Group I. All changes in the controller (e.g., tuning parameters, estimator, constraints) are assumed to be performed manually, since... 

Corrective measures are entered — or those found in previously recorded complaints are accepted — and a specific time frame is defined for solving the root cause. 

So far, we have assumed that a change in an equipment-related MEMS-processing parameter set leads to a defined statistical distribution of geometric and material parameters allowing yield predictions based on functional modeling. However, in addition, we need to take stochastic effects into account and develop testing methods to detect defects and anomalies that detract from product quality and which cannot now be traced to their root causes or controlled sufficiently during production. 

The most common root causes for these problems are examined to define the way to troubleshoot it.
