One of the most important strategic decisions that a firm can make is understanding which business processes need improvement. When information systems are used to strengthen the wrong business model or business processes, the business can become more efficient at doing what it should not do. As a result, the firm becomes vulnerable to competitors who may have discovered the right business model. Considerable time and cost may also be spent improving business processes that have little impact on overall firm performance and revenue.

Student answers will vary. A sample answer is: In terms of B2B e-commerce, Lucky's might be able to procure goods over the Internet, use a private industrial network to coordinate their supply chain with suppliers and manage inventory. Depending on the structure of the gasoline retail business, industry net marketplaces and exchanges might be of use. In terms of B2C e-commerce, there are not many opportunities, as it is inefficient to sell gasoline over the Internet. Lucky's could make sure that its stations are listed in popular location-based mobile services that help drivers find nearby gas stations.

Answer 15

The types of information systems used for different levels of management are transaction processing systems (TPS), management information systems (MIS), decision-support systems (DSS), and executive support systems (ESS). TPS, such as payroll or order processing, track the flow of the daily routine transactions that are necessary to conduct business. They are used by operational managers to manage day-to-day operations. MIS summarize and report on the company's basic operations using data supplied by TPS. They provide middle managers with reports on the organization's current performance and are not highly analytical. DSS also support middle management decisions when these decisions are unique, rapidly changing, and not specified easily in advance. They use advanced analytical models and data analysis capabilities and often draw on information from external as well as internal sources. ESS support senior management by providing data of greatest importance to senior management decision makers. ESS provide a generalized computing and communications capacity that can be applied to a changing array of problems. ESS present graphs and data from many sources through an interface that is easy for senior managers to use, often a portal.

A walkthrough is a peer group review of any product created during the systems development process. During the review, users, management, and the development group participate through various roles. These roles are coordinator, presenter, user, secretary, standard-bearer, and maintenance oracle. The coordinator is the person who plans the meeting and facilitates discussions. The presenter is the individual who describes the work product to the group. Ensuring that the work product meets the needs of the project's customers is the role fulfilled by the user. The person taking notes and recording decisions or recommendations made by the group is the secretary. The standard-bearer role is to ensure that the work product adheres to organizational technical standards. The maintenance oracle is the individual who reviews the work product in terms of future maintenance activities.
