Any organization can expect consistent improvement only if it can develop the work culture in such a way that their employees are delegated with some authority to identify and resolve problems. Kaizen training emphasize that each and every basic rule of the organization should be communicated to all the employees. The clear-cut establishment of methods and rules can very well be felt in the kaizen-type improvement process implemented organization. Following are the basic steps to be followed while implementing a kaizen "event". Of course the organization has the liberty to re-organize the sequence of these steps based on the situation to bring out the highest efficiency.
Kaizen Event Process Step 1: Planning and Preparation
Identify the correct area in the organization that requires the immediate implementation of rapid improvement event. Suggested areas could be the bottlenecks where everything is substantially delayed such as the busy work-in-progress sector; administrative department; or the production area. These areas of an organization are often prone to "mess" and performance or the quality will fall short of customer demands. Unfortunately these lagging would reflect badly on the turnover, marketing and finance of the organization. (i.e., the most "value added" activities).
After identifying the most appropriate production, administrative or a specific segment in the workplace, the focus should be given in particular to "waste elimination" issue prevailing in that department for implementing the kaizen event (i.e., the problems in particular which needs improvement, encompassing the developmental actions such as lead time reduction, quality enhancement, focusing on high production). After identifying the problematic area, the managers have to build a cross-functional team of employees.
Care should be taken to include workers from the administrative and production process departments which are aimed for implementing kaizen event, although at times employees with "fresh perspectives" may find their place in the team. Prior to the training, the entire team should be completely aware of the organization’s rapid improvement process and given appropriate training on the process. Normally, the duration of kaizen events varies from one day to seven days, depending on the length of the process involved and depth of the problem. During the period of training, the employees are expected to have a complete focus on the kaizen event, compromising their daily schedule of work so that they will not have any distraction during the experience.
Kaizen Event Process Step 2: Implementation
The first and foremost work of the team is to identify and clearly understand the "current state" of the targeted process. This would give the team members a common and a clear picture of problem that they are aiming to solve. In general two methods are leveraged to define the prevailing state and identify production related wastes.
Five Whys: Toyota designed and followed a method of asking "why" five times and answering them one by one to understand the root cause of a problem, layer by layer.
Value Stream Mapping: The process elements that form the part of process of transformation, such as the change of raw materials into finished goods, execution of an administrative process, activities, material flow, would be represented in the form of flow chart. Non-value-adding elements in the targeted process can be easily eliminated thorough this process. This is, more or less, the same as that of the technique designed for preventing the pollution in the organization. Value stream mapping can also be applied Phase 1 to identify the areas for implementing the kaizen event.
It is obvious that it is a must to gather data on the targeted process during the kaizen event. The data includes details of overall product quality, scrap rate and source of scrap; product routing and distance traveled, space occupied by the equipment in terms of square feet, changeover strategies, reasons for bottlenecks, details and value of work in progress, details of manpower required to complete a specific task. Specific role of data collection and analysis should be assigned to each of the team members. The large quantity of data collected by the team members will be an added advantage to design value stream maps of the process and will also be very helpful to conduct time studies of respective functions. (e. g takt time, lead-time)
After completing the data collection, it should be analyzed to locate the areas for improvement. The team members would raise queries on the aim of the process, and clearly observe the wastes, reasons for waste and analyze if each element will add value to achieve its target. After identifying this crucial area which has zero value, the team members should discuss on the steps to be adopted for improvement. The ideas that creep out of such brainstorming sessions are often put to test in shop floor in the process of “mock-ups”. The most appealing and fruitful ideas are selected and suggested for implementation. To understand the complete benefits of the kaizen event, each of the employees should keep track of new cycle time and arrive on the benefits gained after eliminating the waste, operator motion, part conveyance, area utilized in terms of square feet and throughput time.
Kaizen Event Process Step 3: Follow-Up
This is the very important phase in the kaizen event as this ensures that the improvements are consistent and not just for time being. After completion of kaizen event, the team members should keep track of performance as a routine, in terms of metrics and measures, to record the gains. Lead and cycle times, process defect rates, movement required, utilization in terms of square feet, can be termed as examples of metrics, even though they would vary with the targeted and administrative process. In general, the follow-up kaizen events are conducted in 30 to 90 days after the first kaizen event with the aim of assessing the performance and locating the follow-up changes that should undertaken to maintain the consistency in performance and development. Normally, targeted process employees are solicited for feedback and ideas. Similar to the 5S method , the feedback and process performance should be displayed on scoreboards in an appealing manner to the employees.
