Root cause analysis (RCA) is a problem-solving process for identifying “root causes” of what has happened.
Those annoying problems just keep popping up so get that feeling of déjà vu. Those problems keep making an unwelcome appearance again and again, daily, weekly, or even monthly.
RCA can help by not focusing on the solution first. But addressing the 'why' does this keep happening?
The prime objective of the root cause analysis is to understand the underlying cause of the problem before implementing solutions so you don't cause more problems.
This simple technique can help diagnose a problem that has negatively impacted business.
Document and define the event, along with a timeline leading up to what went wrong. Who was involved in the procedure and what processes were they using?
Evidence: Must work with evidence-based information.
Problem Statement: Define the problem. Describe the problem, when and where the problem occurred, and the impact it had on the business.
Map Out Process: Map out the chain of events
Cause and Effect: How the problem actually occurred.
Solutions: Verify root cause with data. Develop steps and solutions for prevention. Controlling causes
Instinctively we try to find a solution rather than identify and address the root cause of the problem. This method, root cause analysis doesn’t necessarily result in the best long-term results.
RCA can help answer the question, why the problem happened in the first place. Identify the underlying causes and find an appropriate solution.
Several methodologies have a similar approach like 5 ws and DMAIC all-important parts of six sigma methodology of process improvement and continuous improvement a great way to eliminate business faults.
Six Sigma methodology is not a mysterious magic solution but a well-studied and tested set of tools and techniques that aim to solve problems of inefficiency within your business or projects. These techniques consist of spotting and getting rid of all those faults cluttering your processes and stopping them from running as smoothly and effectively as possible.

Six sigma, lean, and lean six sigma are all focused on improving processes to create more value to the customer.
Lean refers to removing waste in any process, while six sigma refers to optimizing a specific process. Lean focuses on reducing waste from a system, while six sigma’s goal is to improve quality.
