5. What is Work Study?
Work study is a systematical
method of studying work to obtain
the best use of human material
Resources in carrying out the
specified activity

6. *. It is systematic, simple and consistent based on the
handling facts.
*. It is a tools which can be used universally.
*. It is the most penetrating tools of investigation
available to management.
*. It is relatively cheap & easy to apply.
*. To increase the productivity.
*. To increase the profitability.
*. To increase the job security.
*. To make the work easier.
*. To establish fair task for everyone.

8. METHOD STUDY
Method study is a systematical
recording and critical examination of ways of
doing things in order to make improvement.

11. AIMS OF METHOD STUDY
& WORK MEASUREMENT
IMPROVE PRODUCTIVITY
IMPROVE OUT PUT
REDUCE TIME OF PRODUCTION
IMPROVE QUALITY
REDUCE THE COST OF PRODUCTION
INTRODUCE MORE EFFECTIVE &
EASY METHODS

12. STANDARD MINUTE VALUE
(S.M.V)
The time required for an average worker to
perform a given duty under the given working
conditions.
Observed time =average cycle time
Basic time =Observed time X Observed rating
Standard rating
S.M.V = Basic time + Allowance

13. TYPES OF ALOWENCES
MACHINE ALLOWANCES
PERSONEL & FATIGUE ALLOWANCES

14. SMV= BASIC TIME+ALLOWANCES
Cycle Time = 0.60,0.70,0.65,0.60,0.65
Observe time = 3.2 / 5
= 0.64
Rating = 85%
Basic time = Observe time X observe rating
Standard rating
= 0.64 X 85/100
= 0.54
SMV = Basic time +Allowance
= 0.54+15%
SMV = 0.62

#. Irregular distribution of work.
#. Less monitoring.
#. Wrong production.
#. To Fail to identify the skill operator for
said operation.
#. Changing the skill ness of the
operators.
#. No motivational activities for operators.
#. Quality fault.
#. Less effective decision making.
#. Input gap.
#. Machine problem or no supply.

17. TYPES OF LOST TIME
WW- WAITING FOR WORK
CD - CUTTING DELAY
CM - CUTTING MISTAKE
MB - MACHING BREAK DOWN
RW – RE-WORK
PF - POWER FAILURE
CS - COLOUR SHADING
LF - LINE FEEDING

18. HOW TO MEASURE THE IMPROVEMENT
IN A COMPANY
MEASUREMENT TECHNIQUES
1) EFFICIENCY
2) COST PER MINUTE
3) CM PER MINUTE

19. EFFICIENCY CALCULATION
EARNED MINUTES =PRODUCED QTY. X SMV
AVAILABEL MINUTES =SMV EARNERS X WORKING MTS.
EFFICIENCY % = EARNED MINUTES X 100
AVAILABEL MINUTES

20. 1 Example: -
PRODUCTION = 800
GMT SMV = 10
NO OF SMV EARNERS = 20
WORKING MINUTES = 480
AVAILBLE MINUTES = 20 x 480
= 9600
EARNED MINUTES = 10 x 800
= 8000
EFFICIENCY = 83.33%

21. COST PER MINUTE
CPM =
TOTAL OVER HEAD COST FOR THE
MONTH
NO OF OPERATORS X WORKING MINUTES
X EFFICIENCY

22.
TARGET CALCULATION
TARGET FOR A SINGLE OPERATION =WORKING MTS. X EFF%
SMV
TARGET FOR A PRODUCTION TEAM
=NO OF WORKERS X WORKING MINUTES X EFF %
TOTAL SMV
