root cause analysis training course
Source analysis (RCA) may be the formal search for a person or number of interacting true reasons for a challenge. The tough part of professional problem solving is always to find out the right tool(s) able to identifying the true root cause(s) of a problem and not just the signs and symptoms. It is common to find more than just one real cause to some problem, so keep clear in the event you just choose one root cause to any problem. RCA can be pointed at any easy and complex problem but the designated problem solver has to understand what technique to use for several types of problems. For instance, let's look at two different issues looking for solutions:

1. Fast food drive-through window customers complain that the orders take too much time to obtain filled.

2. You can't produce top quality plastic parts produced from your machine which includes 25 knobs on it for the control settings.

You would hopefully apply different techniques to understand the root causes for every of the above problems but often, running a business, that is not the case. All too often, the identical tool is used to resolve every problem. Inside the worst of all scenario, the highly sought after "GOFAAT" Problem Solving Method (Guessing One Factor at A Time) is used to try resolution both for problems.

With all the GOFAAT strategy to solve problem #1 would seem like this: Center manager would play after each client complaint and scold employee Joe eventually, then employee Mary or Larry the next day then scream at the slow cooking french fry machine the next day that. GOFAAT problem solving is a kind of but ineffective approach to attempt problem solving but this fact will not dampen its popularity. It is certainly not called GOFAAT by of its fans but it must be defined as such to reveal some organizations to their shortcomings within their problem-solving efforts.

Using the GOFAAT strategy to solve problem #2 would seem like this: mold machine operator Terry would spin dial number 7 (lucky 7) just a little off to the right when things go wrong with the hope this will make the standard problem go away. Mold machine operator Jerry would spin dial number 13 a little on the left when things go wrong, hoping for a miracle. The Clever mold machine Operator Tito would spin dial number 3 and 5 far to the right when things make a mistake hoping solving the problem. By the way, Terry, Jerry and Tito never speak with each other because they focus on different shifts and management does not allow this group enough time to go over their issues. Unfortunately, this is a common situation that many professional problem solvers encounter when they investigate certain serious problems in a business.

There are roughly 18 different families of Root Cause Analysis Techniques used today. They're down the page. The reduced numbers generally depict simpler plus more unsophisticated techniques and also the higher numbers generally require more training and experience to use those methods correctly. You can find 3 sets of problem solving techniques: Groups A, B and C. Group A techniques can be used by way of a small team of would-be problem solvers with little training. Group B and C techniques require more training and even software to resolve the difficulties.

Group An issue Solving Techniques include Methods #1-5, which include:

1. GOFAAT method (Guessing One factor At A Time)
2. "Whack-A-Mole" Problem-solving method
3. Total Quality Management (TQM) > other Basic Brainstorming Techniques
4. Failure Mode and Effects Analysis (FMEA) > Disciplined Gap Analysis > Closure
5. Plan-Do-Check-Act (PDCA) continuous improvement techniques

Problem-solving Technique #1 in the above list will be the earlier mentioned GOFAAT method (Guessing One factor At A Time). This technique requires no training to use and is employed by someone or even a small team to aim resolution of your problem. Using this tool since the primary means of solving problems will be in the bottom with the scale of sophistication when it relates to competency in problem-solving. It would be reliant on luck if the GOFAAT solving problems method actually solved any issue anywhere.

The 2nd most undesirable Problem Solving Way is what I call the "Whack-A-Mole" method. It is very popular amongst professionals and managers however it is unproductive also it generates lots of wasteful and useless action. Here's how the Whack-A-Mole method works: A specific manager runs a large factory with 550 individuals who sew and glue pieces of material together to produce purses. The manager of this factory lives a complicated life with several disasters erupting in his/her business every couple of days; sometimes a few disasters erupt every day. With all the Whack-A-Mole method, this purse factory manager moves his/her best people to fight a challenge in a corner in the commercial where the big problems are creating chaos. Everything else within the factory turns into a lower priority even though this "Whacking" goes on. Several days later, the Manager moves these problem fighters to battle another disaster that erupted in another corner of the purse factory. The manager doesn't need time and energy to worry when the last fire was fully released, he/she only cares it's tamed down and off of his/her radar screen from the top three issues.

Whack-A-Mole efforts often address the outward symptoms of the problem and never the actual root causes. It's used by frantic, stressed-out, untrained and unenlightened professionals who think that any intense band of activities will invariably yield achievement. Unfortunately, only logical, effective and efficient actions get results. Professionals should find out how to work smarter and not harder.

The GOFAAT and Whack-A-Mole methods can cause chaos and unresolved issues in operation.

The remainder of the Group A Problem Solving Techniques out there are more professional types of problem solving techniques that folks or ad-hoc teams may use following a certain amount of specialty training. The main causes for low complexity problems could possibly be identified with methods #3-5 by using friendly debate, team consensus as well as the democratic technique of team voting. Hard statistics and knowledge verification of root causes are generally not useful for this group or problem solving techniques. These methods could be effectively applied to simpler problems. They may not always set things right . but most of that time period their efforts can pay off, if these methods are employed correctly inside a disciplined way.

Group B Problem-solving Techniques #6-11 include:

6. Lean Manufacturing > Lean Office
7. Time > Motion Studies / Spaghetti Charting
8. Seven Basic Tools of Quality
9. Lean Kaizen Events
10. Process mapping with 10 layers of study
11. Six Sigma and/or Lean > TRIZ

These types of techniques require very accurate information and/or data to achieve success. These tools could be used to address the Not-So-Fast drive-through window customer complaint problem mentioned at the outset of this informative article. A Lean Six Sigma Green Belt, Black Belt, Lean Master or other highly skilled professional has the ability to solve these kind of problems utilizing the right tools on the proper time. Specialized training is required to correctly execute they. These Group B problem solving techniques possess a higher probability of identifying the correct root causes in comparison to Group A techniques. Group B techniques should be employed for damage that is harder to fix. They ought to be applied when simple team brainstorming won't yield the real root causes.

Group C Solving problems Techniques #12-18 include:

12. 3D > Multi-stratification-level graphing
13. Statistical Hypothesis Testing
14. Simple Regression Analysis
15. Multiple Variable Regression
16. Neural Networks > DOEs
17. Off-The-Chart DOE Optimization
18. Artificial Intelligence

These techniques demand a specific amount of accurate data about the problem which will be analyzed with specific software to allow the situation solving method to be successful. These tools could possibly be helpful to address the bad quality plastic parts story mentioned at the start of this short article. The skills necessary to begin using these problem solving techniques will be possessed by Lean Six Sigma Black Belts, Master Black Belts along with other highly trained and trained professionals. These techniques are typically applied when all the other efforts have failed to get to the main cause and solve the problem.
