Work measurement: Job design determines the content of a job, and method analysis determines how a job is to be performed. Work measurement is concerned with determining the length of time it should take to complete the job. Job times are vital inputs for workplace planning, estimating labor costs, scheduling, budgeting and designing incentive systems.
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.
2. Definition of Work
Measurement
Work measurement is the
application of techniques designed
to establish the time for a qualified
worker to carry out specified jobs at
a defined level of performance.
3. OBJECTIVES OF WORK
MEASUREMENT
The main objectives of work
measurement:
To reduce or eliminate non
productive time.
To fix the standard time for doing a
job.
To develop standard data for future
reference.
To improve methods.
4. Techniques for work
measurement
Stop watch time study
Production study
Work sampling or ratio delay study
Synthesis from standard data
Analytical estimating
Predetermined motion time system
5. Stopwatch time study
Procedure for conducting stop watch time
study
Selecting the job.
Recording the specifications.
Breaking operation into elements.
Examining each element
Measurement using stop watch
Assessing the rating factor.
Calculating the basic time.
Determining the allowances.
Compiling the standard time
6. Breaking a job into elements
Repetitive elements
Constant element
Variable element
Occasional element
Man element
Machine element
7. Measuring time with stop
watch
Fly back method
Element time are
obtained directly. No
successive subtraction
needed.
Time is lost in
snapping back of
watch.
So error is introduced.
Short elements may
be missed
Continuous method
Element time are
obtained only by
successive subtractions.
No time is lost in
snapping back.
No such errors , hence
study is accurate
Even short element is get
included
8. Rating factor
Rating is the assessment of the rate of
working of the operator by the work study
man.
If the performance of the operator is
below average , he is given a rating of less
than 100,say 85,90.
If the performance of the operator is
average , he is given a rating of 100.
When the performance of the operator is
above average, he is given a rating of
more than 100,say 85 ,90 etc.,
9. Calculation of basic time
Basic time is the time taken by an
operator of standard performance (rating
100).
BASIC TIME=observed time X (observed
rating/std rating)
example : time or normal time=0.7 x
(120/100)
=0.84 mts
10. Allowances
Rest and personal allowances
Process allowances
Contingency allowances
Special allowances
Policy allowances
11. DEFINITION OF STANDARD
TIME
Standard time is the time allowed to an
operator to carry out the specified task
under specified conditions and defined
level of performance. The various
allowances are added to the normal time
as applicable to get the standard time
Standard time may be defined as the,
amount of time required to complete a
unit of work:
13. COMPONENTS OF STANDARD
TIME
OT – Observed Time
• PRF – Performance Rating Factor
• NT – Normal Time
• PA – Process Allowances
• RPA – Rest and Personal Allowances (Relaxation
Allowance)
• SA – Special Allowances( Interference and Contingency
Allowances)
• PoA – Policy Allowances
• PFD – Personal , Fatigue and Delay Allowances =
(PA+RPA+SA)
15. Uses of work measurement
Manpower planning.
Production planning and scheduling.
Estimating productions costs.
Cost reduction and control.
Comparing alternative methods.
Accepting new orders.
Fixing the selling cost.
