4. 4 of 57© 2006 Prentice Hall Business Publishing Accounting Information Systems, 10/e Romney/Steinbart SYSTEMS, DATA, AND INFORMATION Most systems are composed of smaller subsystems...... And vice versa! The susbsystems should be designed to maximize achievement of the organization’s goals Goal conflict vs. goal congruence

5. 5 of 57© 2006 Prentice Hall Business Publishing Accounting Information Systems, 10/e Romney/Steinbart SYSTEMS, DATA, AND INFORMATION Goal conflict occurs when the activity of a subsystem is not consistent with another subsystem or with the larger system.

6. 6 of 57© 2006 Prentice Hall Business Publishing Accounting Information Systems, 10/e Romney/Steinbart SYSTEMS, DATA, AND INFORMATION Data are facts that are collected, recorded, stored, and processed by an information system.

8. 8 of 57© 2006 Prentice Hall Business Publishing Accounting Information Systems, 10/e Romney/Steinbart Mon 20-9 SYSTEMS, DATA, AND INFORMATION However, when you get more information than you can effectively assimilate, you suffer from information overload. –Example: Final exams week! When you’ve reached the overload point, the quality of decisions declines while the costs of producing the information increases.

46. 46 of 57© 2006 Prentice Hall Business Publishing Accounting Information Systems, 10/e Romney/Steinbart Michael Porter suggests that there are two basic business strategies companies can follow: –Product-differentiation strategy –Low-cost strategy Tue 28-9 THE AIS AND CORPORATE STRATEGY

47. 47 of 57© 2006 Prentice Hall Business Publishing Accounting Information Systems, 10/e Romney/Steinbart A product differentiation strategy involves setting your product apart from those of your competitors, i.e., building a “better” mousetrap by offering one that’s faster, has enhanced features, etc. THE AIS AND CORPORATE STRATEGY

48. 48 of 57© 2006 Prentice Hall Business Publishing Accounting Information Systems, 10/e Romney/Steinbart Michael Porter suggests that there are two basic business strategies companies can follow: –Product-differentiation strategy –Low-cost strategy THE AIS AND CORPORATE STRATEGY

49. 49 of 57© 2006 Prentice Hall Business Publishing Accounting Information Systems, 10/e Romney/Steinbart A low-cost strategy involves offering a cheaper mousetrap than your competitors. The low cost is made possible by operating more efficiently. THE AIS AND CORPORATE STRATEGY Sometimes a company can do both, but they normally have to choose.

50. 50 of 57© 2006 Prentice Hall Business Publishing Accounting Information Systems, 10/e Romney/Steinbart Porter also argues that companies must choose a strategic position among three choices: –Variety-based strategic position THE AIS AND CORPORATE STRATEGY Offer a subset of the industry’s products or services. EXAMPLE: An insurance company that only offers life insurance as opposed to life, health, property- casualty, etc. or oil lubricants.

51. 51 of 57© 2006 Prentice Hall Business Publishing Accounting Information Systems, 10/e Romney/Steinbart Porter also argues that companies must choose a strategic position among three choices: –Variety-based strategic position –Needs-based strategic position THE AIS AND CORPORATE STRATEGY Serve most or all of the needs of a particular group of customers in a target market. EXAMPLE: The original Farm Bureau-based insurance companies provided a portfolio of insurance and financial services tailored to the specific needs of farmers. Or Retirees.

52. 52 of 57© 2006 Prentice Hall Business Publishing Accounting Information Systems, 10/e Romney/Steinbart Porter also argues that companies must choose a strategic position among three choices: –Variety-based strategic position –Needs-based strategic position –Access-based strategic position THE AIS AND CORPORATE STRATEGY Serve a subset of customers who differ from others in terms of factors such as geographic location or size.. EXAMPLE: Satellite Internet services are intended primarily for customers in rural areas who cannot get DSL or cable services.

53. 53 of 57© 2006 Prentice Hall Business Publishing Accounting Information Systems, 10/e Romney/Steinbart Porter also argues that companies must choose a strategic position among three choices: –Variety-based strategic position –Needs-based strategic position –Access-based strategic position These strategic positions are not mutually exclusive and can overlap. THE AIS AND CORPORATE STRATEGY

54. 54 of 57© 2006 Prentice Hall Business Publishing Accounting Information Systems, 10/e Romney/Steinbart Choosing a strategic position is important because it helps a company focus its efforts as opposed to trying to be everything to everybody. –EXAMPLE: A radio station that tries to play all types of music will probably fail. It’s critical to design the organization’s activities so they reinforce one another in achieving the selected strategic position. The result is synergy, which is difficult for competitors to imitate. THE AIS AND CORPORATE STRATEGY

55. 55 of 57© 2006 Prentice Hall Business Publishing Accounting Information Systems, 10/e Romney/Steinbart The growth of the Internet has profoundly affected the way value chain activities are performed: –Inbound and outbound logistics can be streamlined for products that can be digitized, like books and music. –The Internet allows companies to cut costs, which impacts strategy and strategic position. –Because the Internet is available to everyone, intense price competition can result. The outcome may be that many companies shift from low-cost to product- differentiation strategies. –The Internet may impede access-based strategic positions. THE AIS AND CORPORATE STRATEGY

56. 56 of 57© 2006 Prentice Hall Business Publishing Accounting Information Systems, 10/e Romney/Steinbart The AIS should help a company adopt and maintain its strategic position. –Requires that data be collected about each activity. –Requires the collection and integration of both financial and nonfinancial data.
