Production and Operations Management




                    Notes            The concept of productivity encompasses not only a more efficient use of resources, but
                                     also of quality, environmental protection and integrated economic and social development.
                                     Mr. Umesh Panjiar, the Director General of NPC, in a meeting with his senior officers was
                                     concerned with the changes taking place. Though the directions of the changes were clear,
                                     how could  one tackle  the challenges  they posed? He asked Dr. A.K. Saxena, a senior
                                     Director  in  the  organization,  to  suggest  ways  and recommend  changes within  the
                                     organization that would enable it to meet the new challenges.

                                   6.3 Productivity and Production

                                   The term ‘productivity’ must not be confused with production. Productivity is a ratio, while
                                   production relates to a volume. Increased production does  not necessarily  mean increase  in
                                   productivity. If the input of resources goes up in direct proportion to the increase in output, the
                                   productivity will remain the same. And if input increases by a greater percentage than output,
                                   higher production will be achieved at the expense of a reduction in productivity.

                                       !

                                     Caution  It must be remembered that Productivity calculations are based on the assumption
                                     that quality levels are maintained.
                                   If an organization produces more output with the same level of resources, but the quality of the
                                   output is lower, then the  productivity may  not increase. If an  organization produces  more
                                   components,  but they  are  defective and  must be rejected, you  may  have  actually  reduced
                                   productivity.
                                   Cost and quality are characteristics that must be designed into a product in the first place, but
                                   achieving them in the final product is the result of carefully managing the productive resources
                                   of a company.

                                   6.3.1  Enhancing Productivity

                                   Although labour and multifactor productivity measures can be informative, they also can be
                                   deceptive when applied to a firm at process levels.


                                          Example: If a firm decides to transfer some of its work to outside suppliers and lay off
                                   some of its own workforce, the labour productivity will increase. This is because the value of the
                                   firm’s total sales (the  numerator) remains unchanged while the number of employees (the
                                   denominator) drops.
                                   What is measured and the way in which the processes are managed play a key role in determining
                                   productivity improvements. We have to increase the value of output relative to the cost of input.
                                   If processes can generate more output  of  better  quality using  the same  amount  of  input,
                                   productivity increases. If they can maintain the same level of output while reducing the use of
                                   resources, productivity also increases.




                                     Notes  The objectives of improvements in productivity are:
                                         Efficiency

                                         Maximum output
                                                                                                        Contd...
