  1. Operations Management Chapter 1 – Operations and Productivity PowerPoint presentation to accompany Heizer/Render Principles of Operations Management, 7e Operations Management, 9e Some additions and deletions have been made by Ömer Yağız to this slide set. (Revised February 2012)

  2. Some real life scenarios which I used in the past to highlight the importance of Operations Management • fortunately, some of these scenarios are no more valid • many improvements have been realized both in the public and private sector • improvement, or continuous improvement, to be exact, is the right approach to increasing quality, efficiency, productivity, and profitability.

  3. Some Real Life Scenarios in OM • Many of us have witnessed the agony and the suffering (and even deaths) that many senior citizens have had to endure in order to collect their retirement or pension pay from the various commercial banks. This was an episode that repeated every month or every three months, especially in large urban centers. The government organizations and the banks involved in this service process unfortunately did nothing for a long time to improve the situation and increase the quality of this rather routine service (now the situation is a little better)

  4. Some Real Life Scenarios in OM SOME REAL-LIFE SCENARIOS IN OM • You mail a letter by Express Post (APS) to an address in İstanbul. The recipient gets it after 3 days; whereas a package sent to İstanbul via Yurtiçi Kargo (or any of the others) is in the hands of the addressee in 6 hours. Plus, order tracking on Google Earth! QUALITY OF SERVICE? • You buy a shirt from an expensive store and pay lots of money; the buttons come off after the shirt is worn three times. The manufacturer has to really make a special(!) effort to achieve this terrible quality.

  5. Some Real Life Scenarios in OM • A THY plane takes off 40 minutes late from an airport because some Japanese tourists on board forget to identify their baggage before boarding the plane. The plane flies from İstanbul to Ankara in 50 minutes. 40 minutes delay for a 50 minute flight !! HOW DO WE EXPLAIN THIS IN TERMS OF EFFICIENCY, PRODUCTIVITY, AND PROFITABILITY ? (This has been rectified some time ago by the elimination of baggage identification prior to boarding.)

  6. A real episode at Esenboğaon Feb. 6, 2012 Esenboğa Airport, two weeks ago lots of delays and cancellations due to snow and winter conditions an operations manager’s nightmare (kâbus) unhappy and angry passengers THY and TGS service personnel in a very difficult (and unenviable) position

  7. A real episode at Esenboğaon Feb. 6, 2012 • This serious situation had a very happy ending for the passengers and service personnel. HOW? • full and timely information given to passengers face-to-face and via electronic boards • effective and timely catering service to passengers at the gates • very courteous, understanding and helpful attitude by the ground service personnel towards the passengers • nobody had the courage to complain and/or say something bad about the situation, including myself..

  8. Some Real Life Scenarios in OM • Why do some people prefer McDonald’s or similar fast-food restaurants despite the fact that it they are more expensive than comparable food served elsewhere? The same is true for Varan and Ulusoy bus companies.. • When you go to some government office (say, the Tax Bureau) you spend so much you feel terribly exhausted after a very routine task. Is the whole process designed to maximize pain to citizens ? Now, things are a bit different; next slide…

  9. Some Real Life Scenarios in OM • Things are better at the Tax Bureau • attitude change on the part of personnel (civil servant concept) • technology in general, IT in particular, makes the whole process easier, less time-consuming, more efficient, and less costly • errors are minimized • personnel assist those in need of help for filling out forms, etc. • they even offer you free tea at the Hitit Vergi Dairesi..

  10. Some Real Life Scenarios in OM • Things are also better at Çankaya Kaymakamlığı.. • Apostille service unit • 1.5 TL per apostille charged • 2 X 1.5 TL = 3.00 TL • a 3-ply receipt costs 3.00 TL • no charge for 2 or less apostilles; 3 or more apostilles charged at the rate of 1.50 TL per apostille • amazingly clever practice by a public organization!! Olamaz, rüya mı bu?

  11. Some Real Life Scenarios in OM • During registration periods at many universities, poor students have to report to so many different offices and people, and have to wait so long in several lines. Not only the students but also instructors and administrators have to go through the same unpleasant experience. Indeed, we are a society of endless waiting lines! IS THIS SOMETHING ORDAINED BY GOD OR WHAT ?? (Now with online registration, the situation has improved somewhat)

  20. What Is Operations Management? Operations management (OM) is the set of activities that creates value in the form of goods and services by transforming inputs into outputs Production is the creation of goods and services

  21. Transformation Process (Value Adding) OM Involves Managing Transformations Input Output • People • Plants • Parts • Processes • Planning and Control Transformation is enabled by The 5 Ps of OM:

  22. Transformations • Physical and chemical--manufacturing (shoes, PC’s, planes, paint, detergents) • Locational--transportation (rail, sea, air, road) • Exchange--retailing (all kinds of stores, offices), banking ?? • Storage--warehousing (normal and cold storage) • Physiological--health care (hospitals, clinics) • Informational--telecommunications (schools, Reuter Services, Internet and blogs, news media, TV services,METU)

  23. Capital Markets, Stockholders Finance Personnel Suppliers Workers Purchasing Operations Marketing Customers Operations as the Technical Core

  24. Organizing to Produce Goods and Services • Essential functions: • Marketing – generates demand • Production/operations – creates the product • Finance/accounting – tracks how well the organization is doing, pays bills, collects the money

  32. The Critical Decisions • Design of goods and services • What good or service should we offer? • How should we design these products and services? • Managing quality • How do we define quality? • Who is responsible for quality? Table 1.2 (cont.)

  33. The Critical Decisions • Process and capacity design • What process and what capacity will these products require? • What equipment and technology is necessary for these processes? • Location strategy • Where should we put the facility? • On what criteria should we base the location decision? Table 1.2 (cont.)

  34. The Critical Decisions • Layout strategy • How should we arrange the facility? • How large must the facility be to meet our plan? • Human resources and job design • How do we provide a reasonable work environment? • How much can we expect our employees to produce? Table 1.2 (cont.)

  35. The Critical Decisions • Supply chain management • Should we make or buy this component? • Who are our suppliers and who can integrate into our e-commerce program? • Inventory, material requirements planning, and JIT • How much inventory of each item should we have? • When do we re-order? Table 1.2 (cont.)

  36. The Critical Decisions • Intermediate and short–term scheduling • Are we better off keeping people on the payroll during slowdowns? • Which jobs do we perform next? • Maintenance • Who is responsible for maintenance? • When do we do maintenance? Table 1.2 (cont.)

  37. Where are the OM Jobs? Figure 1.2

  38. Where are the OM Jobs? • Technology/methods • Facilities/space utilization • Strategic issues • Response time • People/team development • Customer service • Quality • Cost reduction • Inventory reduction • Productivity improvement
