1. Motion and Time Study
“Time study is the one element in scientific management
beyond all others making possible the transfer of skill
from management to men…..” –Frederick W. Taylor

2. Overview
• Motion and Time Study Defined
– History
• Details about Motion and Time Study
• Motion and Time Study in your
organization
• Real World Example
• Summary of Presentation
• Reading List

3. What is Motion and Time
Study
• Motion Study is designed to
determine to best way to
complete a repetitive job
• Time Study measures how long
it takes an average worker to
complete a task at a normal
pace

4. History of Motion and
Time Study
• Frank B. Gilbreth, Lillian M
Gilbreth
-1885, he begun to develop motion study
• Frederick W. Taylor
-1881, he started to develop time study

5. History of Motion and
Time Study
• Used Separately
• Became interrelated

6. History of Motion Study
• Bricklaying
• Tools Used
– Motion camera

7. History of Time Study
• Started at a machine shop
• home with his family
• Tools
– Stopwatch & Clipboard

8. Tools Used Today…….
• Computers
• Bar codes
• Accustudy Software

9. Details of Motion and
Time Study
• Motion Study
– Improve methods
– It measures distance, or how much you
move to do a job, and how much you get
done in a period of time
• Time study
– Establish standards
– Looked at the average time it took an
average worker

10. Computing Standards
• Estimating
• Performance records
• Stopwatch time study
• Standard data
• Time study formulas
• Work sampling schedules
• Queuing theory

11. How to use Motion and Time
Study in your Organization
• Manufacturing
• Office
• Banks
• Department Stores
• Hospitals

12. How do you decide if you need
to do a Motion and Time Study
• Are costs too high(is there a
problem)?
• Why is there a problem?
• How can it be solved?
• Which alternative is better?
• Choose the best alternative

13. Real World Example A
Company Using Time Study
Cooper Hospital/University
Medical Center
• Problem
– HR Personnel was not very accessible to
employees at the hospital
– Hard to reach the right person to answer
questions
– Inefficient voice-mail system

14. Real World Example A
Company Using Time Study
Cooper Hospital/University
Medical Center
• Tools Used
– Bar-coding system
– Computer
Other
– Determining the busiest time of the day
– Establishing categories

15. Real World Example A
Company Using Time Study
Cooper Hospital/University
Medical Center
• Discoveries
– Majority of calls were for appointments
– Many calls from outside sources for job
verification

16. Results Continued…..
• Implementations
– New systems
– New positions
– Improving service and costs

17. Motion and Time Study
Problem
• There is a group of students
stuffing envelopes. They have to
put three different color-coded
pages in the envelopes(red,
white, orange).

19. Motion and Time Study
Problem
• Compute the standard time
• Compute number of envelopes
stuffed in one hour

20. Solution
• To compute the standard time
Adjust the normal cycle with an allowance factor
of 10 percent
ST= (NT)(1-AF)
= (.1189)(1-.10)
=.1070 min
To compute number of envelopes in one
hour
60 min/.1070min/envelope= 560 envelopes an
hour
