Techniques of scientific management are:
(i) Science, not rule of thumb: Ruleof-thumb methods are traditional approaches that suited organisations in the past. Under mass production, the volume of work had expanded that required scientific methods to manage and control work easily. Accordingly, Taylor suggested that methods of a particular business activity should be scientifically studied prior to their application to avoid mistakes. He suggested introducing standardised and guaranted approaches that led to efficiency in operations.
(ii) Method Study: The objective of method study is to find out one best way of doing the job to maximise efficiency in the use of materials, machinery, manpower and capital. It can be defined as the systematic recording and critical examination of existing and proposed ways of doing work, as a means of developing and applying easier and more effective methods and reducing costs.

(iii) Time study: It determines the standard time taken to perform a well-defined job. The objective of time study is to determine the number of workers to be employed, frame suitable incentive schemes and determine labour costs.
