The four steps of the Improvement Kata are a model of scientific thinking and acting that’s similar to other models of the human creative process. What’s different is that each step of the Improvement Kata pattern includes structured practice routines, or Starter Kata, that make the pattern actionable and teachable. Use the four steps of the Improvement Kata to describe Lean methods for high variant / low volume production environments

MCT stands for Manufacturing Critical-path Time. This metric is used in the Quick Respons Manufacturing theory and indicates the time from the moment a customer submits an order, through the critical path, until the first piece of that order is delivered to the customer. MCT highlight the biggest opportunities for improvement and provides management key insights to adjust the strategy in the right direction.

Single Minute Exchange of Die (SMED) refers to Quick Change Over (QCO), a process designed to reduce the set-up time of a production machine or a production line. The term "tool change" is misleading, since the time from the last good part of the old production lot to the first good part of the new production lot is meant and is better to be called "production change". The difference is that not the pure time of changing a tool is decisive, but also things like the provision of the new material or the parameterization of the machine and the like; The entire time in which it can not be produced.
SMED

Kanban system is an inventory stock control system that trigger signal for production of product based on actual customer requirement. Work items are visualized to give participants a view of progress and process, from start to finish usually via a Kanban board. Work is pulled as capacity permits, rather than work being pushed into the process when requested.

The value stream for HVLV environments is very complex and requires a modified methodology for VSM. A qualitative mapping of the value stream from product order until delivery, followed by systematic interviews give the basis to create an improved value stream. This is especially relevant for companies that lack standard data from before, or environments where data proves difficult to measure.

Organisations should be structured differently to be able to respond quickly in a low-volume environment with customized products. In order to reduce the lead time, it is necessary to break down functional walls and create a team that can process jobs through multiple functional steps. Quick Response Office Cell (Q-ROC) is a multifunctional, cross-trained team located in close proximity, dedicated to all office activities that belong to a FTMS or product family, with ownership of all operations and commitment to lead time reduction.

Little’s law is a tool that can help with determining how long job/parts have been waiting, when timestamp data is not readily available. This law explains that the work in process equals the throughput (so the number of products going through the system), multiplied by the total time it takes.

Product family grouping comprises of a set of approaches that assist layout planning. These approaches assist in designing work cells by allowing the grouping of products into families. The groups or families serve as basis for creating cells, which can then be configured to create the facility layout.

The Kingman’s Equation provides an approximation of the mean waiting time of the components for a single process based on its utilization and variance. The higher the utilization, the higher the impact of variation, this results in longer waiting times and high WIP. Rajan Suri calls this "the magnifying effect".
