HISTORY• Frank Bunker Gilbreth, (July 7, 1868 - June 14, 1924) was the founder of modern study techniques.
• Gilbreth's main goal in working with companies.• Increase efficiency by removing unnecessary movements• Reduce fatigue for employees
• Gilbreth introduces• 17 Therbligs

Recording Techniques
• Recorded information canwrite on a page.
• Information can also saveOn computer other devices.

Examine• Examine all the facts.
• Develop the alternatives
• Each activity is questioned and challenged.

Develop the New Method
• The report should show• All the cost, material,
labour etc• The cost of installing new
method• Executive actions
required to implement the new method.

Defining the improve method
• It also give details regarding
• The tools and equipment used
• Description of method• The diagram of workplace
layout

Develop the New Method
The method which will be developed, will be most practical, economic and effective.

Install
• Gaining acceptance of change by the management• Gaining acceptance of change by the workers
• Keeping a close eye on the progress of implementation of new method

Maintain
• The standard practice by regular routine checks.

How can workstudy improve productivity A case study
• We investigated an existing line which had been working on the order for approximately 10 days, itwas a small order and had several days left to run. The line was set as follows:• There were total 45 operators on the line• There were total 45 operators on the line2 - Supervisors2 -Final checkers2- Roving QC45- Machinists9 - Helpers2- Inline checkers
![Page 25: Method study](https://reader035.fdocuments.net/reader035/viewer/2022062707/55840c3ed8b42a79268b530a/html5/thumbnails/25.jpg)
Starting times
• This factory is supposed to start at 9 AM but everyday it starts at 9.15
• 58 people loosing 15 mins every morning means 14.5 hrs lost in a day and 47 man days lost everymonth.
![Page 26: Method study](https://reader035.fdocuments.net/reader035/viewer/2022062707/55840c3ed8b42a79268b530a/html5/thumbnails/26.jpg)
Space between the operators• Operators hardly have space to sit Distance between some machines is less than 14’’ with their back• This spacing makes it possible to put 46 machines on this line• The ideal distance should be 22 to 24’’• Under these circumstances it isPossible to fit only 38 people onto the line
![Page 27: Method study](https://reader035.fdocuments.net/reader035/viewer/2022062707/55840c3ed8b42a79268b530a/html5/thumbnails/27.jpg)
In the pictures the space is totally inadequate
![Page 28: Method study](https://reader035.fdocuments.net/reader035/viewer/2022062707/55840c3ed8b42a79268b530a/html5/thumbnails/28.jpg)
Helpers• There were a total 9 helpers working outside the line• Doing a lot of matching and unnecessary work• We did not allow helpers to be “Outside” the line,• All of the operations had to be placed in the line• Each person is given a sequential workplace
![Page 29: Method study](https://reader035.fdocuments.net/reader035/viewer/2022062707/55840c3ed8b42a79268b530a/html5/thumbnails/29.jpg)

WIP
• WIP level on the factory floor is too low• The line is not balanced properly • All the WIP that is there is hidden under the tables• Garments are not moving in bundles,• Each piece gets passed to the next operator as it is completed
![Page 31: Method study](https://reader035.fdocuments.net/reader035/viewer/2022062707/55840c3ed8b42a79268b530a/html5/thumbnails/31.jpg)

WIP Hidden under the tables

Summary• Once these problems are identified it is quite a simple matter to re-organise the line,• 40 people were required to perform the work necessary to complete the garments with no loss in output

Summary
It should be noted by the readers that this factory produces small orders –2000 to 5000 pieces onaverage of course the same principles can be adopted in factories with larger orders with the addedbenefit that the improvements made would last longer before the next style goes onto the line.
