Lesson 48 : Mundal's Classes Of Change

Introduction

The famous management specialist Gilbreth opined that instead of using different methods of studying the work process for finding out the simplified method, one has to answer the questions the following questions:

• what is the task to be done,
• When it is to be done,
• By when it should be done
• How it should be done.

Some answers to all the Gilberth questions can be systematically developed through the concept of classes of change. This idea originated in the 1940’s with Marvin Mundel at Purdue University, who classified all examples of simplification into five groups.

The classes are based on the three major factors which influence work time in the home-the product, the household environment, and the worker. Each class is determined by the point where a change is initiated.
