The Toyota Way To Problem Solving
The art of problem solving is constantly trying to evolve and be re-branded by folks in various industries. While the new way might very well be an effective method in certain applications. A tried and true way of identifying and solving problems is the eight steps to practical problem solving developed by Toyota, years ago. The system is structured, but simple and practical enough to handle problems of the smallest nature, to the most complex issues.
Using a fundamental and strategic way to solve problems creates consistency within an organization. When you base your results off facts, experience and common sense, the results form in a rational and sustainable way.
The Eight Step Problem Solving Process
- Clarify the Problem
- Breakdown the Problem
- Set the Target
- Analyze the Root Cause
- Develop Countermeasures
- Implement Countermeasures
- Monitor Results and Process
- Standardize and Share Success
The eight steps to practical problem solving also include the Plan, Do, Check and Act (PDCA) cycle. Steps one through five are the planning process. The doing is found in step six. Step seven is the checking . Step eight involves acting out the results of the new standard.
This practical problem solving can be powerful tool to issues facing your organization. It allows organizations to have a common understanding of what defines a problem and what steps are going to be taken in order to overcome the problem efficiently.
The Eight Steps Broken Down:
Step 1: Clarify the Problem
A problem can be defined in one of three ways. The first being, anything that is a deviation from the standard. The second could be the gap between the actual condition and the desired condition. With the third being an unfilled customer need.
In order to best clarify the problem, you have to see the problem with your own eyes. This gives you the details and hands-on experience that will allow you to move forward in the process.
Step 2: Breakdown the Problem
Once you’ve seen the problem first hand, you can begin to breakdown the problem into more detailed and specific problems. Remember, as you breakdown your problem you still need to see the smaller, individual problems with your own eyes. This is also a good time to study and analyze the different inputs and outputs of the process so that you can effectively prioritize your efforts. It is much more effective to manage and solve a bunch of micro-problems one at a time, rather than try and tackle a big problem with no direction.
Step 3: Set the Target
Step three is all about commitment and focus. Your attention should now turn towards focusing on what is needed to complete the project and how long it will take to finish. You should set targets that are challenging, but within limits and don’t put a strain on the organization that would hinder the improvement process.
Step 4: Analyze the Root Cause
This is a vital step when problem solving, because it will help you identify the actual factors that caused the issue in the first place. More often than not, there are multiple root causes to analyze. Make sure you are considering all potential root causes and addressing them properly. A proper root cause analysis, again involves you actually going to the cause itself instead of simply relying on reports.
Step 5: Develop Countermeasures
Once you’ve established your root causes, you can use that information to develop the countermeasures needed to remove the root causes. Your team should develop as many countermeasures needed to directly address any and all root causes. Once you’ve developed your countermeasures, you can begin to narrow them down to the most practical and effective based off your target.
Step 6: Implement Countermeasures
Now that you have developed your countermeasures and narrowed them down, it is time to see them through in a timely manner. Communication is extremely important in step six. You’ll want to seek ideas from the team and continue to work back through the PDCA cycle to ensure nothing is being missed along the way. Consider implementing one countermeasure at a time to monitor the effectiveness of each.
You will certainly make mistakes in throughout your problem solving processes, but your persistence is key, especially in step six.
Step 7: Monitor Results and Process
As mistakes happen and countermeasures fail, you need a system in place to review and modify them to get the intended result. You can also determine if the intended outcome was the result of the action of the countermeasure, or was it just a fluke? There is always room for improvement in the problem solving process, but you need to be able to recognize it when it comes to your attention.
Step 8: Standardize and Share Success
Now that you’ve encountered success along your problem solving path, it is time to set the new processes as the new standard within the organization and share them throughout the organization. It is also a good time to reflect on what you’ve learned and address any possible unresolved issues or troubles you have along the way. Ignoring unresolved issues will only lead to more problems down the road.
Finally, because you are a true Lean organization who believes continuous improvement never stops, it is time to tackle the next problem. Start the problem solving process over again and continue to work towards perfection.
