The Difference Between Kaizen and kaizen
Big K vs. Little k has different meanings depending on what you are talking about. In baseball, big K means you struck out looking and little k means you struck out swinging (some use a forward k or a backward k too). But in implementing lean thinking, my colleagues and I have used it to refer to the different types of thinking regarding continuous improvement.
‘Big K’ kaizen refers to the type of continuous improvement where everyone improves their work everyday. Every employee is working to drive waste out of their work in order to improve the business on a daily basis. This is the ideal state of lean that we would like to achieve.
While ‘Big K’ kaizen is a great future state, most companies starting a lean transformation do not have much employee engagement. This is where ‘Little k’ kaizen can help. ‘Little k’ kaizen is what most people refer to as a kaizen event. An organized event where a cross functional team including people from the process, suppliers of the process, and customers of the process are sequestered, typically a week, to work on improving the process.
Most organizations have not had much employee engagement in the past. This is usually due to many reasons that usually can be placed back on the shoulders of leadership. The event based ‘Little k’ kaizen allows a way to kick start the employee engagement by gathering employees together to work on improving a process. The key is to listen to the employees and let them implement their ideas with leaderships support. ‘Little k’ kaizen is not a forum to push management ideas out onto the employees and have them execute it.
I have seen the ‘Little k’ kaizen process be very successful as I have helped organizations kick start the employee engagement. The pitfall is treating ‘Little k” kaizen like it is the same as ‘Big K’ kaizen. Most organizations are so happy with the ‘Little k’ kaizen process results and the employee engagement from the event that they plan more of them. They continue to get these great results and before you know it they set a goal to have X amount of ‘Little k’ kaizen events per year.
The events are not what are important. It is engaging the employees in problem solving. The trick is to know your culture and build on the momentum from the ‘Little k’ kaizen event. As leaders we must continue to engage our employees after the ‘Little k’ kaizen event and push them to make changes to improve the process as they come up with the ideas every single day, this is ‘Big K’ kaizen. Don’t wait until the next ‘Little k’ kaizen event. When employees are looking for ways to improve the process everyday and not waiting for the next event or management to make the changes, then you are getting to true ‘Big K’ kaizen. It isn’t easy, but it is well worth it when it happens.
