A flowing river will be pure than stagnant water, since pure water will be coming into it from the source and contaminated water is replaced with pure water in it. Just reminded the importance of flow. With this example lets move to flow in a manufacturing industry. Let’s start … What is flow Flow is […]
These three names, Muda, Mura and Muri do not sounds familiar to our normal language slang because these are the Japanese words. Muda is the Japanese word for waste, Mura is the Japanese word for unevenness and, Muri is the Japanese word for Overburden. These words represents anything, which is against lean manufacturing. So, initially
The ultimate aim of value stream mapping (VSM) is to save money or reduce production cost. To save money, we need to initially identify which all things or activities are consuming money without delivering any value to the customer. I think you all know what is a value, its anything which customer is willing to pay for.

Thinking process of a lean practitioner will be explained in this article, in 4 steps. How a lean practitioner think for achieving lean manufacturing. Before discussing how a lean practitioner think, we shall discuss what is lean. In this article we will take manufacturing industry as example. One request, before leaving this article please write
Suppose takt time of a product is 3.5 seconds and cycle time an operation is 14 seconds. Here I will explain how to calculate no of workstations from takt time and cycle time, for completing this operation so as to meet the customer demand. No of workstation = Cycle time / takt time = 14/3.5

Line balancing is done to reduce or eliminate the waiting time in the workstations of an assembly line which runs in one piece flow. Thus we can utilize the resources such as manpower and machinery/equipment more effectively. Line balancing definition Line balancing is a method for eliminating idle time in assembly line and also for
Why Why Analysis is a method used for finding out the root cause of a problem or symptom. In this method a series of why questions are asked about the problem. And finally we will reach the root cause of the problem. Why Why Analysis is used for root cause analysis of a problem, which
Bottleneck is anything which will restrict the flow. In a manufacturing industry bottleneck will be an operation and flow means the flow of material or information. Watch Training Video at the end of this article. Also Download an excel template from the end of the article. Suppose there is an assembly line with 4 operations
A waste is anything which do not add any value to the customer requirement. Once again a waste is any material or operation or activity, which do not add any value to the customer requirement. There are 8 types of waste in a manufacturing industry. I will explain one by one with example. Before that,
Takt time is the time in which a manufacturer should produce a product so as to satisfy customer demand. This can be called as pulse of lean manufacturing. How to calculate Takt time Suppose a manufacturer have a customer who wants 500 units per day. Presently the manufacturer works in two shifts and working time
