DEFINITION
Motion and time study refers to knowledge dealing withDetermination of preferable work methods.Determination of the time required to preform work.
Methods design and labor and machine resource requirements determination.
3
DEFINITION
Motion Study consists of procedures for analysis and improvementThe raw materials
The design of the outputs
The process or order of work
The tool, the workplace and equipment for each step in the process
The human activity used to perform each step
4
DEFINITION
Time study consists of procedures for Determining the amount of time required Under certain standard conditions of measurement Involving some human, machine, or combined activity Time study will be used to refer to all time measurement techniques
InterrelationshipTime measurements are often a part of the basis on which alternative methods are compared.
The combined term is used to denote all three phases of activity: method determination, time appraisal, and the development of material.

FIELD OF APPLICATION
Basic problems needing solutionsDetermining a feasible and preferable method of accomplishing the work.
Determining the required amount of human or machine work time.
Designing the work and to determine the amount of the time use of the various kinds of resources required to perform it.
ProductivityRatio of units of output per unit of input.Productivity indexes are the value of such ratios divided by a similar ratio for a base year.
When the effort is to enhance labor productivity, the techniques of work measurement are vital.
6
FIELD OF APPLICATION
EffectivenessRefers to the success of an organization in achieving its objectives.
Motion and time study obviously are of great use in improving effectiveness.
EfficiencyProductivity is efficiency of outputs, effectiveness efficiency of results.
Managerial usesMotion and Time study may well be used to provide a means of communication and cooperative activity.

MANAGEMENT DEFINED
1. Determine quantitative objectives for a given span of time in conformance.
2. Plan a series of programs for achieving the desired objectives.
3. Determine the workload.
4. Determine the resources required to perform the workload.
5. Acquire authority to employ these resources to perform the workload
6. Use the resources to accomplish the workload.
7. Determine the workload accomplished the resources consumed.
8. Determine the amount of the program accomplished.
9. Determine the degree of accomplishment of the objectives.

INTRODUCTION TO MOTION STUDY
Divided into three categories1. Category 1: For selecting the class of change
2. Category 2: For delineating the outputs
3. Category 3: For examining the appropriate details of the work
10
SEQUENCE OF USE OF THE TECHNIQUES
With substantive outputsUse of a technique chosen from those in category 1
This is followed by the use of a technique from category 3
With service outputsUse of a technique chosen from category 2This is followed by the use of some work measurement or time study technique
After the time has been measured, may be followed with the use of a category 3
