The Pursuit of Creativity

In my years of running Kaizen events, I never saw anything as powerful as a creativity approach called 3P – Production Preparation Process. The goal is to eliminate waste in the design of a new or existing process or product in the maximum way possible, unlocking the creativity of the team in ways most of them have not experienced. In 2016 I was fortunate enough to experience this approach through the eyes of the man who invented it, Chihiro Nakao. Sensei Nakao was a former Toyota employee who was sent out to help other companies at the behest of the originator of the Toyota Production System, Taiichi Ohno.

There are eleven steps to the approach, and although they may seem simple or counterintuitive on the surface, they are truly deep and complex and can lead to amazing breakthroughs. A short article will not do this justice, but perhaps it will motivate you to learn more about 3P.

A typical 3P Kaizen event takes 4 ½ days. They are long days, extremely engaging and exhausting, but at the end, the team will have a solution to an important problem that they are seeking. They will also have simulated their solution at a scale that will tell them whether or not it is truly viable.

Background – The team needs to understand certain key Lean principles and terms, such as Takt time, just in time, right sized equipment, and 5 whys prior to initiating the 11 steps of 3P. They also need to know how to use certain tools, such as the Standard Work Combination Sheet and the Fishbone Diagram.

Voice of the Customer – The team needs to hear directly from the customer to understand what is expected from them. There should be a direct exchange with the customer, so there can be no doubt about what is needed. Criteria for the solution is shared, so the team can measure their efforts against the criteria during the 3P.

Step 1 – Determine the Function of the Product or Transformational Step. As a first step, the team must identify what the customer would like them to accomplish in the simplest of terms. They will be challenged to describe this in two words, using a noun and a verb only. For example, a lightbulb does many things, but at its essence, it either “gives light” or “provides heat”. What is the product or process that the customer is most interested in? The team must avoid thinking about what is currently happening, but rather the bare essence of what the customer is willing to pay for, no more, no less.

Step 2 – Define the Essence of the Function Using Keywords. What words are the simplest way to describe what the customer is asking for? The team should generate as many key words as possible and then sketch them out on paper or sticky notes for everyone to see. The act of identifying the key words and sketching them is a way to drive the creativity of the participants forward. Some examples of key words are: drill, shear, guide, roll, and fasten.

Step 3 – Look for Examples of Keywords in Nature. In this step, team members do research and find examples in nature of the keywords. No examples should be man-made. Nature has used millions of years to perfect the simplest ways to accomplish tasks. Again, it is better to draw the examples than just list them. For example, if a key word is grip, then an example in nature could be an eagle’s talon gripping its prey. This step takes time and most team members will initially resist putting great effort into it, but with perseverance, they will make important discoveries about simple ways to perform complex tasks. Each team member should draw at least three examples, so that they expand their thinking beyond what they already know.

Step 4 – Sketch Examples and Examine “What is Happening” to Enable the Function. This next step is to examine in greater detail what allows nature to accomplish the keywords. What causes an eagle’s talon to grip its prey? Team members attempt to attain a greater understanding of the mechanism that is being utilized by nature through research and drawing. More examples are encouraged, as team members dig deep into their understanding and creativity.

Step 5 – Sketch Background and Conditions of the Function. This step takes a deeper dive at the function and the surrounding conditions that allow the function to occur in nature. More than just the eagle’s talon gripping the prey, what is happening with the muscles and nerves in the talon that allow it to grip? What interactions are occurring, and how are they able to do so?

Step 6 – Combine Ideas from Nature and Create Sketches. Each team member is challenged to come up with at least seven ways of solving the original problem using what they have learned from nature and other ideas that they may have. People generally have three alternatives in mind, so getting to seven causes them to think beyond their normal approach and have a bit of fun. It is not unusual to hear laughter during this step as people start to relax their creative minds and let go of their paradigms of what is possible.

Step 7 – Rapid Prototyping (Moonshine). This is the step that brings everything together and turns the ideas into reality. By reviewing, grouping, and prioritizing all of the many ideas shared across the team, the team picks two or three ideas to build. The team should break up into sub-teams so that each idea can be worked on simultaneously. The team is encouraged to use any materials available to them to demonstrate their concepts. The team assesses their prototypes against customer criteria and the
Seven Flows: Flow of People, Flow of Material, Flow of Parts, Flow of Products, Flow of Equipment, Flow of Information, and Flow of Engineering. They learn and improve as they go and are expected to make multiple iterations as they build. This build should be in three dimensions, so it is critical to have enough space and materials for team members to work. The term “Moonshine” refers to the historical practice of building stills in the woods by the light of the moon during Prohibition and using any available materials.

Step 8 – Conduct Trials and Gather Real Data. After building prototypes, they must be tested. Data is collected and compared to the customer criteria. As the comparisons are made, improvements are identified but not yet implemented. Often, the team identifies a better way to approach the problem and plans out the improvements for the next round of prototyping and moonshining.

Step 9 – Select the Three Best Designs Based on Criteria. During all of the prototyping and moonshining, it is not unusual to create variations on the original ideas and have many options to choose from. In this step, the team uses the original customer criteria to score all options and narrow down to three best designs to continue working on.

Step 10 – Continue Simulating and Gather and Evaluate Data on the Top Three Proposals. The team continues to do work on their proposals, learning about them, simulating them, and improving them. Any problems that occur are fixed on the spot, with as little discussion as possible. The act of building rather than discussing expands the creative process. At some point in this step, time will run out, so the team should set a target time to get all information and simulate how their idea will work.

Step 11 – Presentation of Solutions. The team demonstrates to the customer how each option works and shares the data and criteria evaluation. It is similar to a high school science fair, in that the customer acts like the judge and delivers constructive criticism and asks deep questions to the team. Rather than a Power Point presentation, this is a demonstration in 3D, with physical activity, so it’s easier to understand what the team is presenting.

The 3P approach is a highly engaging way to drive breakthrough creativity in teams that have the opportunity to participate. It has been shown to save precious project time and drive cost out of the finished product or process. Some teams saved 6 months in their Innovation cycle time by using 3P. Other teams have said that using 3P revealed viable options that they would never have pursued otherwise. I encourage you to consider this approach and learn more about it.
