Source Analysis Tools and Techniques
root cause training courses
Root Cause analysis (RCA) will be the formal hunt for a person or band of interacting true reasons for a challenge. The difficult part of professional solving problems would be to know the right tool(s) capable of identifying the real root cause(s) of the problem and not simply the symptoms. Extremely common to discover not only one source to a problem, so be skeptical should you just find one root cause to your problem. RCA could be pointed at any basic and complex problem nevertheless the designated problem solver has to know what technique to use for several kinds of problems. For example, let's look at two different issues in need of solutions:
1. Junk food drive-through window customers complain that their orders take too long to acquire filled.
2. You cannot produce top quality plastic parts created from your new machine that has 25 knobs about it for that control settings.
You would hopefully apply different strategies to get the root causes for each of the above problems but often, in operation, that is not the truth. All too often, the same tool is applied to solve every problem. In the for the worst situation scenario, the popular "GOFAAT" Problem Solving Method (Guessing One Factor at any given time) is utilized to try resolution for both problems.
With all the GOFAAT approach to solve problem #1 would look like this: Center manager would play after each client complaint and scold employee Joe eventually, then employee Mary or Larry the very next day after which scream in the slow cooking french fry machine the day after that. GOFAAT problem solving is a very common but ineffective way to attempt problem solving however this fact will not dampen its popularity. It is certainly not called GOFAAT by of the fans but it must be called such to expose some organizations with their shortcomings inside their solving problems efforts.
With all the GOFAAT approach to solve problem #2 would look like this: mold machine operator Terry would spin dial number 7 (lucky 7) a little to the right when things fail with the hope this is likely to make the quality problem go away. Mold machine operator Jerry would spin dial number 13 just a little left when things go wrong, dreaming about a miracle. The Clever mold machine Operator Tito would spin dial number 3 and 5 far off to the right when things fail expecting solving the situation. In addition, Terry, Jerry and Tito never talk to each other simply because they work with different shifts and management doesn't allow this group the time to go over their issues. Unfortunately, it is a common situation that many professional problem solvers encounter once they investigate certain serious problems in business.
You will find roughly 18 different categories of Root Cause Analysis Techniques used today. They're listed below. The lower numbers generally depict simpler and much more unsophisticated techniques as well as the higher numbers generally want more experience and training to apply those methods correctly. You can find 3 sets of problem solving techniques: Groups A, B and C. Group A techniques may be used with a small team of would-be problem solvers with little training. Group B and C techniques require more training as well as software to resolve the problems.
Group A Problem Solving Techniques include Methods #1-5, which include:
1. GOFAAT method (Guessing One factor At any given time)
2. "Whack-A-Mole" Solving problems 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
Solving problems Technique #1 in the above list is the earlier mentioned GOFAAT method (Guessing One factor At A Time). This technique requires no training to apply and could be utilized by an individual or perhaps a small team to attempt resolution of your problem. The usage of it since the primary means of solving problems would be at the bottom with the scale of sophistication if this pertains to competency in solving problems. It would be dependent on luck when the GOFAAT problem-solving method actually solved any issue anywhere.
The second most undesirable Problem-solving Strategy is things i call the "Whack-A-Mole" method. It's very popular amongst professionals and managers but it's unproductive and it generates plenty of wasteful and useless action. This is how the Whack-A-Mole method works: A certain manager runs a sizable factory with 550 those who sew and glue pieces of material together to make purses. The manager of this factory lives a complicated life with several disasters erupting in his/her business every few days; sometimes a few disasters erupt each day. While using Whack-A-Mole method, this purse factory manager moves his/her best visitors to fight an issue in one corner in the commercial where the big complaints are creating chaos. Anything else in the factory receives a lower priority even though this "Whacking" continues on. A few days later, the Manager moves these problem fighters to fight another disaster that erupted in another corner from the purse factory. The manager doesn't need time for you to worry in the event the last fire was fully create, he/she only cares it had become tamed down and from his/her radar screen with the best three issues.
Whack-A-Mole efforts often address the signs and symptoms of the problem and never the actual root causes. It is utilized by frantic, stressed-out, untrained and unenlightened experts who feel that any intense number of activities will always yield achievement. Unfortunately, only logical, effective and efficient actions get results. Professionals should try to learn how to work smarter rather than harder.
The GOFAAT and Whack-A-Mole methods can result in chaos and unresolved issues in operation.
The remainder of the Group A Problem Solving Techniques on the list tend to be more professional kinds of solving problems techniques that folks or ad-hoc teams are able to use after having a specific amount of specialty training. The basis causes for low complexity problems could be identified with methods #3-5 by using friendly debate, team consensus as well as the democratic process of team voting. Hard statistics and data verification of root causes are usually not useful for this group or problem solving techniques. These methods may be effectively used on simpler problems. They won't always get it right but most of times their efforts can pay off, if these techniques are used correctly in 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
Most of these techniques require very accurate information and/or data to reach your goals. These power tools might be accustomed to address the Not-So-Fast drive-through window customer complaint problem mentioned at the start of this article. A Lean Six Sigma Green Belt, Black Belt, Lean Master or another very skilled professional has the capacity to solve these kinds of problems by using the right tools on the proper time. Specialized training must correctly execute these techniques. These Group B solving problems techniques use a higher probability of identifying the right root causes when compared with Group A techniques. Group B techniques needs to be used for damage that is more difficult to solve. These techniques needs to be applied when simple team brainstorming will not yield the actual root causes.
Group C Problem-solving 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
They demand a certain quantity of accurate data about the problem which will be analyzed with specific software to allow the situation solving method to be successful. These power tools might be helpful to address the not so good quality plastic parts story mentioned at the beginning of this informative article. The abilities necessary to start using these problem-solving techniques will be possessed by Lean Six Sigma Black Belts, Master Black Belts and other very skilled and trained professionals. These methods are typically applied when other efforts didn't work to get at the root cause and solve the issue.
