Work Study

Question 0

Why work study

Answer 0

To increase or improve the productivity in long and short term

Question 1

Define work study

Answer 1

A management tool. It is a scientific study of method and time taken carry out a particular operation or series of operations to obtain facts about operations.

Question 2

What are the objectives of work study

Answer 2

• the most effective use of plant and equipment
• the most effective use of human effort
• the evaluation of work

Question 3

What is the nature of the theory for a work study

Answer 3

• organized common sense, human ingenuity and creation of tools
• functional and assumed to be natural
• critical suggestion and taking nothing for granted
• predictability and control over quality
• maximize use of complete labour and capital

Question 4

What are two techniques used in a work study

Answer 4

• Method study

- work measurement

Question 5

Why make a work study? (Scientific approach)

Answer 5

• each component of the job production can be analyzed down to the smallest component part
• optimum material, plant and labour to do the work

Question 6

Why work study

Answer 6

• all the component parts then closely integrated into a programme of production
• each component ready on time
• correct balance of quantities
• in the right place
• flow of work logical
• efficient ways of doing the job, short travel distance
• machines employed to capacity, no breakdowns or delays
• adequate supervision at all times

Question 7

What is method study used for

Answer 7

To improve existing and/or proposed method of doing work

Question 8

What are the objectives of method study

Answer 8

1. To examine the ways of doing work to develop easier and more effective methods of production
2. To observe, record and analyse the operation
3. To examine the performance of a operation that can be improved to make more effective use of the resources

Question 9

What are the stages in method study

Answer 9

Select the task to study
Record the facts about it
Examine these
Develop
Install/implement it
Maintain it

Question 10

What can the selection I method study be based on

Answer 10

1. Cost of work
2. Delays
3. Safety
4. In-house technical support
5. Supply of materials
6. Supply of materials
7. Issues
8. Limitation of site environment
9. Demand of plant
10. Demand of labour

Question 11

Who has to agree on a method study

Answer 11

Senior management team

Question 12

What is important when recording the facts in a method study

Answer 12

• prepare a factual record of how the operation actually takes place
• before and after comparisons made
• use standard symbols to plot the work involved with the activity
• use standard symbols to plot the work involved with the activity
• Record in a process chart

Question 13

What structure is does the examine phase have

Answer 13

Purpose (what is being done? Why? What else could be done?)
Place (where? Why? Where should?)
Sequence (when? why then? When else? When should?)
Person (who? Who else? Who should?
Means (how, why, how else, how should)

Question 14

What’s the purpose of develop a new method in a method study

Answer 14

• knowledge of the possibilities; new machinery, effects of removing a stage,
• developing solutions requires the designer to have knowledge of new methods and equipment and the technical feasibility
• a chart of the new system in a pictorial model others to see the new system and evaluate it

Question 15

Install/implementing in a method study

Answer 15

1. New method once agreed and costed must be installed
2. Staff consultation, briefing, and training needed
3. Installation may require a detailed project plan and budget
4. A new method could be installed in one line whilst the old method continue
5. If a method is installed immediately over an old method then there needs to be complete certainty that it is going to work
6. How is the problem of staff training to be resolved if it has not been installed yet
7. Discussion with operative and staff
8. Approval by management
9. Cost savings/time savings established
10. allow running in period to test the new ways of doing things

Question 16

Maintain

Answer 16

• a new method needs new sequences of operator action and probably different perspectives
• every member of the operations team needs to be committed to the new method
• the process chart needs to be updated with the new method ans associated documentation modified
• maintenance by regular checking
• May drift back to the original practice
• review
• incorporate any valid amendments to the new process
• operating instructions remain live documents

Question 17

What effort is required in a work measurement procedure

Answer 17

Select - work to be measured
Define - method to be used
Measure- quantity the work involved (direct and indirect measurement)
Obtain standard time
Establish - target time for defined method

Question 18

What is included within the selection in a work measure

Answer 18

• time required for the average worker to carry out particular task
• not only about how the worker operates
• other influence are involved
• need to inform everyone involved why the exercise is being undertaken

Question 19

Define in a work measure include

Answer 19

Complete description and it’s elements

• the operation
• the operator
• prevailing conditions
• the specified way of doing it

Question 20

Measure In a work measure is

Answer 20

• time study techniques
• rating (the average worker, how good the worker)
• calculation (of standard time for the job)

Question 21

Obtain and establish

Answer 21

Allowed time for the operation to be completed and issued for use
