BCIS 1305 Test 1 Review Chapter 1 Five Component Framework for “computer based” Information Systems Hardware, Software, Data, Procedures and People Management Information System (MIS) MIS refers broadly to a computer-based system that provides managers with the tools for organizing, evaluating and efficiently running their departments. In order to provide past, present and prediction information, an MIS can include software that helps in decision making, data resources such as databases , the hardware resources of a system, decision support systems , people management and project management applications , and any computerized processes that enable the department to run efficiently. The application of information systems to solve business problems The development and use of information systems that help businesses achieve their goals and objectives. Most Important Component of MIS Your mind and your thinking Quality of your thinking: you cannot increase your basic IQ by you can dramatically increase the quality of your thinking. You can change the way you have programmed your brain to work. Information: knowledge derived from data. Difference that makes a difference. Data presented in a meaningful context. Information is always understood in a context and that context varies from one user to another. Therefore, information is always subjective. What makes “good” information: Accurate, Timely, Relevant, Just Barely Sufficient and Worth its cost. Resources of MIS: The three key resources for MIS, People, Information, Information Technology This may not be the professor's view of the correct answer, but from the point of view of this senior MIS person, the information itself is the most crucial element. If the computers are destroyed, they can be replaced. If the staff all walk out, more can be hired. But if the information is erased or corrupted, the loss can be irreparable. Granted there should be backups of data, but those may be up to 24 hours old and they may themselves be corrupt or unrecoverable. Good people would never let that happen, you say? Usually; not always. Mistakes happen. Systems are attacked. Failing hardware and poorly-written software can corrupt data. What if corrupt data are not discovered for months? The daily backups are of no use; they contain the same bad data. Go back to before the corruption started? Fine, but when was that? And how many months of data can a business do without? Protect your data, and hire the best people, across the board. Check your backups and data regularly, and test your assumptions
