Introduction to Operations Management (Session 2) Prof. (Dr.) Kaustav Kundu, Assistant Professor (QT and OM area), Office No. 306



Learning Objectives  Discuss problems with outsourcing Explain productivity and competitiveness Necessity of operations strategy and its different steps



Case study questions: How responsible is a company for the actions of its supplier? Of its supplier’s supplier? When the country in which the supplier exists fails to take action? What are the difficulties in relying on monitoring to enforce suitable working conditions in supplier factories? What other remedies would you recommend? Compare Apple’s supplier problems Nike’s and those of the apparel industry. Would the same remedies work in each case? Which case is more difficult? Why?



Productivity and Competitiveness  The OECD (Organization for Economic Cooperation and Development) defines competitiveness as “the degree to which a nation can produce goods and services that meet the test of international markets while simultaneously maintaining or expanding the real incomes of its citizens”  The most common measure of competitiveness is productivity.  Productivity is calculated by dividing units of output by units of input.  Productivity =



𝑂𝑢𝑡𝑝𝑢𝑡 𝐼𝑛𝑝𝑢𝑡



 Single-factor productivity compares output to individual inputs, such as labor hours, investment in equipment, material usage, or square footage.  Multifactor productivity relates output to a combination of inputs, such as (labor + capital) or (labor + capital + energy + materials).



Measures of Productivity  Single-Factor Productivity 𝑂𝑢𝑡𝑝𝑢𝑡 𝐿𝑎𝑏𝑜𝑟



𝑂𝑢𝑡𝑝𝑢𝑡 𝑀𝑎𝑡𝑒𝑟𝑖𝑎𝑙𝑠



𝑂𝑢𝑡𝑝𝑢𝑡 𝐶𝑎𝑝𝑖𝑡𝑎𝑙



 Multifactor Productivity 𝑂𝑢𝑡𝑝𝑢𝑡 𝐿𝑎𝑏𝑜𝑟+𝑀𝑎𝑡𝑒𝑟𝑖𝑎𝑙𝑠+𝑂𝑣𝑒𝑟ℎ𝑒𝑎𝑑



 Total Factor Productivity



𝑂𝑢𝑡𝑝𝑢𝑡 𝐿𝑎𝑏𝑜𝑟+𝐸𝑛𝑒𝑟𝑔𝑦+𝐶𝑎𝑝𝑖𝑡𝑎𝑙

where capital can include the value of equipment, facilities, inventory, and land.



Calculating Productivity Osborne Industries is compiling the monthly productivity report for its boards of directors. From the following data, calculate (a) labor productivity, (b) machine productivity, and (c) multifactor productivity of output per dollars spent on labor, machine, materials, and energy. The average labor rate is $15 an hour, and the average machine usage rate is $10 an hour.



Units produced Labor hours Machine hours Cost of materials Cost of energy



100,000 10,000 5,000 $35,000 $15,000



Drawbacks of productivity statistics  Productivity is a relative measure. Productivity statistics can be misleading.  For example, a country or firm may increase productivity by decreasing input faster than output. Thus, although the company may be retrenching, its productivity is increasing.  Productivity statistics also assume that if more input were available, output would increase at the same rate. This may not be true, as there may be limits to output other than those on which the productivity calculations are based.  Furthermore, productivity emphasizes output produced, not output sold. If products produced are not sold, inventories pile up and increases in output can actually accelerate a company’s decline.

Determining order winners and order qualifiers. Positioning the firm.



Deploying the strategy



Key Takeaways  Outsourcing is not always beneficial. The companies need to take proper actions in order to make it effective.



 There are different ways of measuring productivity. Productivity can be single factor, multiple factor or total factor.  The productivity statistics is misleading. If both numerator and denominator change, it will be hard to guess the productivity.  How to make proper strategy planning and different steps of strategy formulation.
