1. Identify and describe information systems (IS) used in each level.
ANSWER:
Computer-based or manual system that transforms data into information useful in the support of decision making. MIS can be classified as performing three functions:
(1) To generate reports-for example, financial statements, inventory status reports, or performance reports needed for routine or non-routine purposes.
(2) To answer what-if questions asked by management. For example, questions such as "What would happen to cash flow if the company changes its credit term for its customers?" can be answered by MIS. This type of MIS can be called Simulation.
(3) To support decision making. This type of MIS is appropriately called Decision Support System (DSS). DSS attempts to integrate the decision maker, the data base, and the quantitative models being used.

2. How do these IS help the employees and managers achieve their objectives.
ANSWER:Management by Objectives (MBO) is a process in which a manager and an employee agree upon a set of specific performance goals, or objectives, and jointly develop a plan for reaching them. The objectives must be clear and achievable, and the plan must include a time frame and evaluation criteria. For example, a salesperson might set a goal of increasing customer orders by 15 percent in dollar terms over the course of a year.
MBO is primarily used as a tool for strategic planning, employee motivation, and performance enhancement. It is intended to improve communication between employees and management, increase employee understanding of company goals, focus employee efforts upon organizational objectives, and provide a concrete link between pay and performance. An important factor in an MBO system is its emphasis on the results achieved by employees rather than the activities performed in their jobs.

3. Cite a local or national company that makes use of these IS and identify the benefits and drawbacks/lapses of these IS.
ANSWER:One of the most interesting changes in business practices is telecommuting, namely doing work in places other than the corporate offices. The extent of telecommuting has been on the rise during the 1990s and it is expected to rise rapidly during the next few years. A major driving force in the spread of telecommuting is the increased availability of cost-effective supportive information technologies. The tasks performed by telecommuters are expanding. While the early telecommuters performed repeated transactions (such as processing insurance claims at home), today's telecommuters can perform at home, or on the road, almost any task that they do at the office. Thus, their information needs have been changed. This paper examines the various tasks performed by telecommuters and surveys the major supporting information technologies. Special attention is given to electronic mail, accessibility to databases and networks, desk top teleconferencing, personal digital assistants (PDAs), screen sharing, workflow systems, idea generation, and distributed group decision making. Also, Lotus Notes is viewed as a major computing environment that will facilitate telecommuting. Technological developments in an integrated services digital network (ISDN), an asynchronous transfer mode (ATM), wireless communication, and local area network (LAN) connectivity will have a major impact on the growth of telecommuting and so will the resolution of managerial issues such as appropriate controls and security, cost-benefit justification, training and ownership and maintenance of the necessary equipment at home.
