1. How hardware & software support in various MIS activities of the organization? Explain the transaction stages from manual system to automated systems?
Hardware support for MIS
Generally hardware in the form of personal computers and peripherals like printers, fax machines, copier, scanners etc are used in organization to support various MIS activities of the organization.
1.6.1 Advantages of a PC: you can find the following advantages a personal computer offers:
a) Speed — A PC can process data at a very high speed. It can process millions of instructions within fraction of seconds.
b) Storage — A PC can store large quantity of data in a small space. It eliminates the need of storing the conventional office flat files and box files which requires lots of space. The storage system in a PC is such that the information can be transferred from one place to another place in electronic form.
c) Communication — A PC on the network can offer great support as a communicator in communicating information in the form of text and images. Today a PC with internet is used as a powerful tool of communication for every business activity.

Input unit is used to give input to the processor. Examples of input unit —Keyboard, scanner, mouse, bar code reader etc.
A processor refers to unit which processes the input received the way it has been instructed. In a computer the processor is the CPU — Central Processing Unit. It does all mathematical calculations, logical tasks, storing details in the memory etc.
Output unit is used to give output s from the computer.
Examples of output unit — Monitor, printer, speakers etc.
2. Explain the various behavioral factors of management organization? As per Porter, how can performance of individual corporations be determined?
3. Compare various types of development aspect of Information System? Explain the various stages of SDLC?
Planning of Information Systems

4. Compare & Contrast E-enterprise business model with traditional business organization model? Explain how in E-enterprise manager role & responsibilities are changed? Explain how manager is a knowledge worker in E-enterprise?
5. What do you understand by service level Agreements (SLAs)? Why are they needed? What is the role of CIO in drafting these? Explain the various security hazards faced by an IS?
A service-level agreement (SLA) is a contract between a network service provider and a customer that specifies, usually in measurable terms, what services the network service provider will furnish. Many Internet service providers (ISP)s provide their customers with an SLA. More recently, IS departments in major enterprises have adopted the idea
6. Case Study: Information system in a restaurant.
A waiter takes an order at a table, and then enters it online via one of the six terminals located in the restaurant dining room. The order is routed to a printer in the appropriate preparation area: the cold item printer if it is a salad, the hot-item printer if it is a hot sandwich or the bar printer if it is a drink. A customer’s meal check-listing (bill) the items ordered and the respective prices are automatically generated. This ordering system eliminates the old three-carbon-copy guest check system as well as any problems caused by a waiter’s handwriting. When the kitchen runs out of a food item, the cooks send out an ‘out of stock’ message, which will be displayed on the dining room terminals when waiters try to order that item. This gives the waiters faster feedback, enabling them to give better service to the customers. Other system features aid management in the planning and control of their restaurant business. The system provides up-to-the-minute information on the food items ordered and breaks out percentages showing sales of each item versus total sales. This helps management plan menus according to customers’ tastes. The system also compares the weekly sales totals versus food costs, allowing planning for tighter cost controls. In addition, whenever an order is voided, the reasons for the void are keyed in. This may help later in management decisions, especially if the voids consistently related to food or service. Acceptance of the system by the users is exceptionally high since the waiters and waitresses were involved in the selection and design process. All potential users were asked to give their impressions and ideas about the various systems available before one was chosen.
- In the light of the system, describe the decisions to be made in the area of strategic planning, managerial control and operational control? What information would you require to make such decisions?
- What would make the system a more complete MIS rather than just doing transaction processing?
- Explain the probable effects that making the system more formal would have on the customers and the management.
1. A management information system (MIS) is an organized combination of people, hardware, communication networks and data sources that collects, transforms and distributes information in an organization. An MIS helps decision making by providing timely, relevant and accurate information to managers. The physical components of an MIS include hardware, software, database, personnel and procedures.
