We need to find secondary and tertiary causes, or sub causes I like to refer to them as.Įach time we probe, we get a better understanding of the problem. As this is a root cause analysis tool, we need to delved deeper. In step 4, you identified the top level causes. – Customer satisfaction: Poor customer relations with 3 customersĮnsure that everyone agrees the problem specifically and clearly. – On Time Delivery: 12 hours behind plan. When: 8.00 AM (and is a consistent fault) What: Machine 3 suffered 12 hours down time through computer program error – On time delivery affected: The customer didn’t receive their product on time Production is now 4 hours behind 2 additional customers will experience late deliveries When: During the night shift (Approximately 2.00 AM) What: Material was purged on the K2 mixing machine which meant 4 hours of downtime Here are some examples to get you into the right problem statement frame of mind. How did it impact your goals? We need to be clear how it affected our goals.Where did it happen? We want to be able to pinpoint exactly where the problem happened.When did it happen? We want to see if a certain time had an impact.What happened? We want to know quickly and concisely, the problem.Try to describe your problem in terms of: If your problem is too open ended, your fishbone analysis will not be as targeted. Write the problem statement in the Problem Statement box (the fish head).īe very specific here. On a whiteboard or Flipchart paper, now draw a Problem Statement Box. Many cause and effect chains must be seen to really overcome the problem.Īnd by using the Fishbone diagram, it’s easy to see them. There may be a number of factors that contribute to the effect (the problem). By continuously asking why, you can uncover deeper unseen causes By brainstorming them on one visual diagram, it provides an effective way of seeing why a problem happens and all the possible factors that may affect this. It’s these cause and effect relationships which create problems. The fishbone diagram is a simple and visual way to see cause and effect. The ‘bones’ running off each cause category represent possible deeper causes that are linked together.Running off the spines are the main cause categories.The head of the fishbone represents the problem.It’s history stems from a Japanese organisational theorist called Kaoru Ishikawa.Īnd it’s simply used to show a cause and effect relationship of a number of factors, relating to a specific problem.įishbone diagrams have the following characteristics: Don’t stop until you know the problem and the root causes.Ī measure of a quality focused business is their speed at identifying problems, conducting root cause analysis and implement RCA solutions, quickly.Ĭalled a Fishbone because of it’s appearance… And it all stems from what’s caused Root Cause Analysis (or RCA for short)…. These bullet points represent true problem solving. Check to ensure the problem has been eliminated.Put actions in place to eliminate these causes.Ascertain the root causes to the problem.Before you know it, there are many issues that are rearing their ugly heads, because none of them (or very little) have been completely resolved in the first place.īy completely resolved, I mean sufficient time spent to: Often, a short while later, the same problem returns, causing more mayhem. By doing this, they simply put band-aids over their problems to get the job or service completed.
They encounter something and rally around to get over it.
The problem with most businesses is that they never really fix problems.
I’ve mentioned it a number of times on this blog and in discussions with teams.
