-
Make life easier and more comfortableGet job done completely and faultlessGet people achieve higher level of living standard
-
Problem SolvingProcess AnalysisOperation AnalysisMicromotion StudyTime Study (Work Measurement)etc.. such as Applied Statistics
-
Knowledge dealing with the systematic determination of a preferable work method with the time required for the uses of human and equipment to perform such work as well as a development of material & tools to make the established method and time practical
-
Procedure to describe, systematic analyze and improve work methodThus considerWork processRaw materialsDesign of the outputWorkplace, tools, equipment at each step of the work processHuman activities

How to develop a better methodGraphic Tools for the analysis5W + 1H QuestionsECRSChecklistsMore details: Micromotion study
-
What is done?Who does the work? Where is the work done? When is the work done?How is the work done?
-
Output of the questionssObjectives of the workCreativity: Could any other people do this work better in other place, at other time, using other method?
-
Along with 5W1H, TRY US!Eeliminate all unnecessary workCcombine operations (elements of work)Rrearrange sequence of operationsSsimplify the necessary operations
-
Improve the equipment performanceIs current production lot size too large or too small?
-
Create and Change the layout to eliminate distanceIncrease the lot size per tripDo the loading & unloading time take too long?Improve transportation equipment
-
Create Improve inspection method Are the quality inspections and volume inspections being done at separate processes? Try to combine the two at the same process
-
Can we create to eliminate temporary storage? Can retention times be shorten?
