Computer Based Information Systems (CBIS) – Meaning and Types

Computer Based Information System (CBIS) is an information system in which the computer plays a major role. Such a system consists of the following elements: Hardware: The term hardware refers to machinery. This category includes the computer itself, which is often referred to as the central processing unit (CPU), and all of its support equipment’s. Among the support equipment’s are input and output devices, storage devices and communications devices. Software: The term software refers to computer programs and the manuals (if any) that support them. Computer programs are machine-readable instructions that direct the circuitry within the hardware parts of the Computer Based Information System (CBIS) to function in ways that produce useful information from data. Programs are generally stored on some input / output medium-often a disk or tape. Data: Data are facts that are used by program to produce useful information. Like programs, data are generally stored in machine-readableContinue reading

Elements of a System

Elements of a System The important elements of a system are; Output and Inputs Processor(s) Control Feedback Environment Boundaries and Interface Outputs and Inputs A major objective of a system is to produce an output that has value to its user. Whatever the nature of the output, it must be within the line with the explanations of the intended user. Inputs are the elements that enter the system for processing. Output is the outcome of processing. A system feeds on input to produce output in much the same way that a business brings in human financial, and material resources to produce goods and services. It is important to point out here that determining the output is a first step in specifying the nature, amount and regularity of the input needed to operate a system. For example in systems analysis, the first concern is to determine the user’s requirements of aContinue reading

Types of Information Systems

Conceptually, information systems in the real world can be classified in several different ways. For example, several types of information systems can be classified conceptually as either operations or management information systems. 1. Operations Support Systems Information systems have always been needed to process data generated by, and used in, business operations. Such operations support systems produce a variety of information products for internal and external use. However, they do not emphasize producing the specific information products that can best be sued by managers. Further processing by management information systems is usually required. The role of a business firm’s operations support systems is to efficiently process business transactions, control industrial processes, support enterprise communications and collaboration, and update corporate databases. 2. Transaction Processing Systems Operations support systems include the major category of transaction processing systems (TPS). Transaction processing systems record and process data resulting fro business transactions. Typically examples areContinue reading

IT Tools and Technologies for Managers

1. Customer-Focused e-Business A key strategy by managers for becoming a successful e-business is to maximize customer value. This strategic focus on customer value recognizes that quality rather than price becomes the primary determinant in a customer’s perception of value.

Thereby, encouraging cross-functional collaboration with customers in product development, marketing, delivery, service and technical support. A successful Customer-Focused e-business attempts to ‘own’ the customer’s total business experience through such approaches as: Letting the customer place orders directly, and through distribution partners Building a customer database that captures customers’Continue reading

Case Study on MIS: Information System in Restaurant

Case Summary: 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.Continue reading

E-Business Models

The term E-business (electronic business) is similar to terms like e-mail, e-commerce, helping not only in buying, selling but also in servicing customers and collaborating with business partners. Today, major corporations are rethinking their businesses in terms of the internet and its new culture and capabilities. Companies are using web to buy parts and supplies from other companies, to collaborate on sales promotions, and to do joint research. Exploiting the convenience, availability, and world-wide reach of the Internet, many companies, have discovered how to use the Internet in a better way. After the first wave of e-business, ‘bricks and clicks’ businesses — those with both a traditional and e-commerce approach — find that, while they already have sound financial resources, they, too, must find the right e-business model(s) for generating profitable revenue streams from the Internet. In terms of operationalising the e-business strategy a variety of e-business models are nowContinue reading
