GilbrethMotion Study(Brick Laying Study)TaylorTime Study or Work Measurement (Pig Iron Study)
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

What are revealed information?time consumedtransportation distancerequired man-hourWhat Next ?
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?
