Productivity

q Productivity is defined as the output per unit of input. q Measure of process improvement q Productivity improves standard of living (productivity is closely link with quality) q Productivity : a measure of performance q Effective utilization of Man Machine Material Method and capital. q Important for manufacturing as well as service industry 

Productivity 4

qIt is frequently measured using labor or technological

benchmarks. q qHigher productivity can be obtained by improving worker skills,

improving technology, additional management training, efficient distribution systems. q qProductivity is positively impacted by capital-intensive

processes. q qProductivity is directly related to economical growth q q

Productivity q A capital-intensive process is a production process that uses a high ratio of capital to labor inputs. For example the U.S. auto industry is a capital intensive industry. q q Industries where significant capital investments have made an impact include agriculture and computer manufacturing. q q Productivity can also be improved by investing in human capital.

q And what is human capital? It is the knowledge and skills possessed by the work force. This includes the amount of education, training, and experience the workforce contains. q q Higher productivity is derived from using highly educated workers in capital-intensive production processes. Increasing the number and quality of high school and college graduates improves human capital and the productivity of the work force. q

Techniques

Value Analysis & Value Engineering

Value..

Desired performance (P) Value = Overall Costs (C)

Value can be increased by either improving

the Performance or reducing the cost.

Value Engineering Value Engineering : Technique applied to identified

optimum value solution during new product development. Value Analysis : Technique applied for improving existing product process or service. Objective is to reduce cost bit to improve the performance and quality. It is a powerful problem-solving tool that can reduce costs while maintaining or improving performance and quality requirements. 

Value Analysis, is a systematic and function-based

approach to improving the value of products, project or service.

Work Study

Work Study  It is a Systematic examination of methods of carrying on activity so

as to improve the effective use of resources and to setup standards of performance for the activities carried out   Work Study succeeds because it is systematic both in the

investigation of the problem being considered and in the development of its solution.   Work study focuses on process & human activity and can increase

productivity at a lower cost. 

Objective  Finding better ways of doing work.  Increased production and productivity(by Effective utilization of

resources & Avoiding waste).  Improvement of conditions, which involve an element of excessive

fatigue or danger  Optimum utilization of human, machine and material for

accomplish the goal.  Reduced costs - labour, material, overheads 

Def : Examination of existing and propose way of doing a work



with a view to develop and apply easier and more productive method of doing the same 

Method study is the systematic recording and critical examination



of ways of doing things in order to make improvements.

Need of Method Study 1. Bottlenecks in the system resulting in long delivery time or unbalanced workflow. 2. 3. Idle plant labor shows under utilization of resources . 4. 5. Poor moral of workers may affect the quality of the product. Due to this there may be high absentism. 6. 7. Inconsistent earnings also advocate for the review of prod’n method.

 Improved layout of office, working areas of factories.  Improved design of plant and equipment.  Effective handling of materials.  Improved flow of work.  Improved safety standards.  Standardization of methods.  Better working conditions.

Selection of job  Finding out problem area  There are three factors that should be kept in secd when

selecting a job. 1) Economic consideration





2) Technical consideration



3) Human consideration



Recording  Collection of data , observation  There are various recording techniques, selection of work is

depend on nature of work  The success of the whole procedure depends on the accuracy with

which the facts are recorded, because they will provide the basis of both the critical examination and the development of the improved method.  Recording serves essentially as a basis for following analysis and

examination .

Work measurement  Work measurement is the application of techniques designed to

establish the time for a qualified worker to carry out a task at a defined rate of working.

  The basic objective of work measurement is to determine the allowed

time for a qualified worker to perform a given task, using a prescribe method, under a given set of condition.   Management tool   Objective of worker Measurement :     

Reduce cost Reduce unwanted time Increase the motivation and set benchmark for improvement Measure & Improve performance of resources To schedule work and allocate capacity

Data collected is use for  Manning  Task planning  Estimation of production cost  Cost reduction  Process improvement  Incentives  Set standard data  Training others  To check performance

Work measurement

Time Study

Work sampling

Time study  Time study is a technique of work measurement to established time

for qualified worker to carry out a specific task under specific conditions  Most widely used technique  Applicable for short cycle repetitive jobs  Direct observation  Using stopwatch  Time require to perform a task during a cycle

Time study procedure  Select the task  Select the operator  Record necessary details  Break the task  Measure the duration of every elements  Measure normal time  Calculate allowance  Calculate standard time of the job

Work Sampling nWork

Sampling is a technique of finding the percentage occurrence of

certain activity by random observation and statistical sampling. nLabor

standard is set using output and % of time worker spends on tasks.

nInvolves nThe

observing worker at random times over a long period.

work-sampling technique collects data at intervals of time.

nStatistical

element is based on this law of probability: If a procedure is

observed a sufficient number of times, the results will be as reliable as when the procedure is observed continuously over a period of time.

Work Sampling  Used for 

delay studies

Setting labor standards

Measuring worker performance

The Seven Step Work Sampling Procedure  Compute the sample size required  Take a preliminary sample to obtain an estimate of the

parameter value  Prepare a schedule for observing the worker at appropriate

times  Observe and record worker activities; rate worker performance

The Seven Step Work Sampling Procedure - continued nRecord

the number of units produced during the applicable

portion of the study nCompute

the normal time per part

nCompute

the standard time per part

Advantages over Time Studies  Longer time periods can be studied,  Does not require analyst to make continuous observations,  Operator is not subject to continuous observation,  Many operations & workers can be studied by a single analyst.  Require less cost  Time study is more labor-intensive method of data collection  Time study for Short cycle work processes work sampling for long-cycle

work processes. 

Business Process Reengineering

 Process : Set of activity which converts input into output  Business Process : Set of logical activity follows sequentially

to get some business outcome  Reengineering : fundamental rethinking and radical

redesign

Business Process Reengineering  The fundamental rethinking and radical redesign of business

processes to achieve dramatic improvements in critical contemporary measures of performance, such as cost, quality, service, and speed 
