Six Sigma Root Cause Analysis For Your Business

Analyzing the root cause of a problem is its real solution and this fact is gaining momentum across industries. It has evolved as a methodology over the years and is most effective when Six Sigma Certification holders apply it. Six Sigma is another problem-solving approach that relies on data-driven decisions. Both the processes combined together form an effective force for reducing variations in operational procedures, and defect elimination. Six Sigma Root Cause Analysis practitioners assist the management in organizations and enable teams to resolve issues with a structured approach. This ensures that the flaws don’t recur in future. 

The Secret Steps To Perform Six Sigma Root Cause Analysis

Why Get Certified In Six Sigma Root Cause Analysis?

Apart from a career boost there are several other strong reasons for becoming certified in Six Sigma Root Cause Analysis. 

  • RCA is a robust technique to detect underlying causes of functional errors. It involves multiple assessment rounds to arrive at the conclusion. This adds to the credibility of an individual’s demonstration of Six Sigma expertise. 
  • Pursuing the Six Sigma Certification is an opportunity for individuals to learn the application of statistical tools and data. This makes them adept at process improvement which is an added advantage for conducting root cause analysis. 
  • The different levels of Six Sigma Certification such as Black Belt, White Belt back the root cause analysis skills. This competency gets more recognized on a global platform. 
  • Finance, manufacturing, telecommunications, healthcare – the choice of career options is diverse for certified professionals. Industries these days cannot do without RCA and hence, is gaining more demand. 

Six Sigma Root Cause Analysis is a potential tool for employees to establish the culture of continuous improvement in workplaces. Individuals possessing the Six Sigma Certification are providing organizations with the access to invaluable RCA technique. 

What Are The Steps To Perform Six Sigma Root Cause Analysis?

Confirm the problem

The first step of RCA involves determining the problem. A team of individuals engages in the task of assessing the factors that influence the problem in question. They prepare a statement containing the precise and clear definition of the problem. This is the stage for finding clear answers to questions like “Does the problem affect consumer needs?”

Collect information

This is a very crucial stage where individuals knowledgeable in Six Sigma Root Cause Analysis gather data. It comprises the information revolving around the occurrence, recurrence, contributing factors, and observed impact of the problematic incident. Six Sigma certified professionals are adept at documenting the event specifications and characteristics. 

Determine potential factors

The role of Six Sigma Certification comes into play when the RCA team needs to create a series of events. This is essential for identifying the causal factors of the problem. The participant team conducts brainstorming sessions to ask questions to themselves and create a sequence of associated events. Certified team members apply Six Sigma tools to prepare a visual of the relation between the problem and the events. 

Find the causes

Apart from the RCA team members, other relevant departments and stakeholders also need to be active at this stage. The outcome of this phase is the selection of the root cause/causes. This calls for the implementation of Six Sigma Root Cause Analysis tools. 

Prioritization of causes

Not all of the root causes possess equal effect. So, this is the stage when team members need to rank their priorities. This ranking determines which of the root causes call for immediate attention. Greater the impact of the cause, higher is its priority. Executioners also emphasize the number of causal factors a cause has triggered to measure its impact. 

Recommend solutions

The final step of Six Sigma Root Cause Analysis is about addressing the causes and implementing necessary solutions. Interviewing people, conducting consumer surveys, or brainstorming provide useful recommendations for problem-solving. 

Enhanced productivity and increased efficiency are the prime goals of this methodology. Six Sigma Certified professionals apply the aforementioned steps for RCA. They also measure the efficacy of the implemented solutions from time to time to make necessary adjustments. 

What Are The Tools Of Six Sigma Root Cause Analysis?

Six Sigma Certification holders are most eligible for performing Root Cause Analysis in organizations. They know how to make the most of the tools as listed here:

Fishbone diagram 

This tool helps in classifying several causes of a problem in different groups. These groups facilitate the navigation of challenges that determine the impact of causes. In this diagram, the fishbone showcases the primary causes while the head represents the problem. The secondary causes too can be plotted next to each primary causal factor. 

Fault tree analysis 

FTA (Fault Tree Analysis) functions on the boolean logic for detecting the root cause. The top of the chart tree indicates the problem while the affected subsystems constitute the branches. This tree is a visualization of the problem’s impact on different areas of a system. Thus, it is most feasible for detecting system risks, and it works on the method of deduction. 

5 Whys analysis

This tool originates in the Lean methodology and helps in streamlining a problem’s root causes. The method is simple yet effective and involves asking questions to oneself for even the slightest clue. 5 ‘whys’ or questions are adequate for finding out the right answer in RCA. This provides an evaluation of the relation between different root causes and clarifies the sequence of events concerning the problem. 

RCA Through Six Sigma Training is apt for those looking for insights into this technique. Training enables professionals to understand the challenges of Root Cause Analysis and how to overcome them. It creates an awareness among an organization’s employees striving to attain the broader business goals.
