Work study involves systematically analyzing work methods to improve efficiency and productivity. Key aspects include setting performance standards, reducing unnecessary work, improving quality, and evaluating human performance. The main resources needed are manpower, materials, machines, money, and methods. Conducting time and motion studies allows establishing standard times for tasks. This helps determine targets, costs, staffing needs, and more. Common challenges include worker resistance and production issues.

25. Definition of time study: Time study is a
work measurement techniques for
recording the time of performing a certain
specific job or its elements carried out
under specified conditions and for analyzing
the data so as to obtain the time necessary
for an operation to carry out at a define rate
of performance.

26. •Stand diagonally behind the operator about
1.5-2.0meters.
•Take more than 20 observations.
•Record relevant detailed about the method
and the machine.

27. •Method study should be done.
•Method study produces the required quality.
•For new methods plenty of time should give to
settle down.
•Operator should be rate between 70%-110%.
•Inform the supervisor before start.
•Operator should not be disturbed during the
study.
•Ensure operator gets enough supply.

28. •Definite and fixed location.
•Pre position reduces reach.
•Gravity feed.
•Tools and materials, best sequence of
motions.
•Drop deliveries whenever possible.
•Chair height of the work place & comfort.
•Color contrast with that of the work &
reduce eye fatigue.

29. •Obtaining and recording all the information available
about the job the operative and surrounding condition
which is likely to affect the carrying out the work.
•Recording a complete description of the method
breaking down the operation into elements. (Break
down the elements).
•Examining the detailed breakdown to ensure that the
most effective method of motions is being used and
determining the sample size.

30. •Measuring with a timing device (stop watch) and
recording the same time taken by the operation to
perform each elements of the operation.
•At the same time assessing the effective speed of the
working of the operator relative to the observes
concept of the rate corresponding to standard rating.
•Convert the observed time to basic times (basic time
calculation).
•Adding necessary allowance to the basic time.
•Determining the standard time for the operation

31. Rating is the assessment of the workers rate
of working relative to the observer’s concept
of rate corresponding to standard place.

32. •Standard worker is not available all the
time.
•Different people take different times.
•To compare the observed worker with a
qualified worker.
•To convert the observed time to a time a
qualified worker would likely to take.

33. •Establish in mind how standard worker should work.
•Compare the effective needs of the observed
worker with standard worker.
In terms of
Skills: The techniques apply to perform the job.
Effort: Expression of the will to work efficiency.

34. 50 : Very slow - not interest
75 : steady –unhurried
100 :brisk –businesses like (standard)
125 : Very fast – above average
150 : Outstanding- unusual

35. An element is a distinct part of a specified job selected
for convenience of observation measurement and
analysis.

36. •To give a systematic detailed specialization of
work.
•To identify subsequent omissions or insertions
elements.
•Operation may not work at the same place
throughout the operation.
•To extract the time for certain parts.
•To keep the concentration of the time study
officer.

37. •Repetitive elements: Repetitive elements are elements which are
occurring every work cycle of an operation.
•Occasional elements: Occasional elements are an element which does not
occur is every work cycle of an operation but which may occur at regular or
irregular intervals.
•Constant element: Constant element is an element for which the basic
time remains constant whenever it is performed.
•Variable elements: Variable elements are elements for which the basic
time varies in relation to some characteristics of the product equipment or
process.

38. •Machines elements: Machines elements is an elements
performed automatically by any process physical, chemical or
otherwise that once standard cannot be influence by worker
except to determinate it prematurely.
•Governing elements: Governing elements is an elements
occurring a longer time with in a work cycle than that of any
other elements which is being performed.
•Foreign elements: Foreign elements are elements observed
which does not form a part of the operation being studies.

39. •Easily identifiable beginning and ending (break point).
•As short as can be conveniently timed (between 6.30
sec).
• Re present naturally unified distinct segment of
operation.
•Separate machine and manual elements if possible.
•Elements which do not occur every cycle should be
timed separately before starting a time study.

40. •Standard Performance is the rate of output which
qualified workers will naturally achieve without over
exertion as an average over the working day or shift.
Provide that they know adhere to the specified
method and provided that they are motivated to
apply themselves to their work.
This performance is denoted as 100 on the standard
rating and performance scales.

41. •Achieve smooth & consist movements.
•Acquired rhythm.
•Responds more rapidly to signals.

48. As per the ISO classification there are mainly 6 stitch
classes-
•Class -100 chain stitch
•Class -200 hand stitch
•Class -300 lock stitch
•Class -400 multithread chain stitch
•Class- 500 over edge chain stitch
•Class -600 covering stitch

49. Each loop is interconnected with the
following with the same thread. Opposite
side of the seam look different. This stitch
type can be very easily unlocked by running
back from the last stitch to the first. The
seam is generally quite extensible. It is often
used for temporary stitching.

50. Formed by single threads being passed
completely from one side of the material to
the other. The thread is held by the material
originally made by hand, some of them can
now also be formed by m/c.

51. Formed by two different thread systems. A needle
thread introduced from one side of the material
is interlaced with and under thread supplied from a
spool from the other side. The stitch is different to
unpick and both side have the same appearance
generally, lock stitch are less extensible then chain
stitch seam. This type finds the widest application. Two
or more thread lock stitch using needle thread and one
bobbin thread.

52. This also formed two thread systems. The loops of
the needle thread are drawn all the way through
the material and they are interconnected on the
under side by thread supplied from a lopper.Top and
bottom side have a different appearance. The stitch
can easily be unpicked is quite extensible special
applications are elastic cross over seams in knitted
fabric and seam which have to be flat.
Multi thread chain stitch using one or more needle
thread and one or more loopers thread.

53. Over edge chain stitch are formed from one or more
needle or lopper. Needle thread loops are taken all the
way through the materials and interconnected with
themselves or with other thread. At least one thread
system passes around the edge of the materials. Over
edge chain stitch of various types are used to neaten
and to bund the cut edge woven and to knitted
materials.
Multithread over edge chain stitch using needle thread
and lopper thread.

54. This stitch types is generally formed from
three thread systems. The over thread lie
on the top surface and are held in place
by the needle threads which in turn are
interlaced on the back of the seam by the
lopper threads. They are used specially
for making flat extensible seam in knit
fabric.
