Lean Thinking

Introduction

The technique of value stream mapping is used in lean manufacturing in order to critically analyze and then design flow of materials and information. This is essential to manufacture and deliver the product to the customer. This technique is applicable for all value chains (Mike & Shook, 2003, pp. 22). The assessment of the seven value stream mapping tools is as follows:

Process activity mapping

This is an industrial engineering technique, also known as process analysis and consists of five stages including; the study of process flow, the identification of wastes, a consideration for re-arranging the process sequence, improvisation of the flow pattern to make it more efficient and a check being kept to ensure that everything is taking place accordingly, and no extra processes are involved (Hines & Rich, 1997, pp. 46)

Supply chain response matrix

In this mapping technique, the constraints of lead-time are highlighted for a particular process. Improvement can be brought about in lead times and amounts of inventory after studying these constraints.

Production variety funnel

This technique takes it roots from the operations management area. The method of IVAT analysis consists of activities related to A, I, T or V forms where;

"I" plants comprise of production of various similar items. "V" plants process raw materials into a diverse range of completed products that are diversified. "A" plants, on the other hand, have numerous raw materials but a limited range of completed products, such as those in major assembling industries. "T" plants are based on a wide grouping of products from a limited number of raw materials, contrasted into partially processed parts that are then used for customized final products (Hines & Rich, 1997, pp. 47). This method helps in deciding about reduction in inventory and in applying changes to the product ...
