Chapter 1 Summary

Q1: Why Is Introduction to MIS the Most Important Class in the Business School?
 
MIS is the most important class due to future businesses need to e able to assess, evaluate, and apply emerging information technology to business. MIS teaches this through abstract reasoning, systems thinking, collaboration, and ability to experiment. Abstract reasoning is the ability to make and manipulate models which we will work with in every chapter. Systems thinking is being able to take components of a model and connect inputs and outputs into a sensible whole that explains what you observed. Collaboration means to exchange critical feedback. Ability to experiment is the process of deciding what to invest in and being prepared to do something that is unknown and not being afraid to fail.
 
Q2: What is MIS?
 
Management information system is defined as the development and use of information systems that help businesses achieve their goals and objectives. Five component framework is Hardware/Software/Data/Procedures/People. MIS needs to be developed and used. Information systems need to be constructed. MIS must be used to achieve goals and objectives of a business. There is no reason to construct and use information system if they do not help the people of a business answer questions.
 
Q3: How Can You Use the Five-Component Model?
 
Hardware/Software/Data/Procedures/People.  Hardware and Software is the computer side. Procedures and People are the human side. Hardware and People are the actors. Software and Procedures are the instructions. Data is the bridge between the two. The people are the most important part of MIS. Information needs to be analyzed. A perfect information system cannot insure a correct answer to a question. High tech means more work from the hardware and software side as opposed to low tech which means the majority of the work is on the human side. Components are ordered by ease of change and disruption that it occurs. Hardware is easy as compared to people.
 
Q4:  Why Is the Difference Between Information Technology and Information Systems Important?
 
Information technology (IT) refers to the products, methods, inventions, and standards that are used for the purpose of producing information.  IT pertains to the hardware, software, and data components.  An information system (IS) is an assembly of hardware, software, data, procedures, and people that produces information.  The difference between the two is that you cannot buy an IS.  You can buy IT; you can buy/lease hardware, you can license programs and databases, and you can even obtain predesigned procedures.
 
Q4: What is information?
 
Information is knowledge derived from data.  Information is data presented in meaningful context.
 Information is data processed by summing, ordering, averaging, grouping, comparing, or other similar operations. Information is subjective. Information is always understood in a context, and the context varies from one user to another.
 
Q6:  What Are Necessary Data Characteristics?
 
Good information is conceived from accurate, correct, and complete data and is has been processed correctly as expected.  Businesses must be able to rely on the results of their information systems.  Good information must also be timely.  It must be available in time for its intended use.  Data should be relevant both to the context and to the subject.  Data needs to be sufficient for the purpose for which it was generated but just barely so.  Data isn't free, but it must be worth its cost.
 
Q7:  2024?
 
There is no perfect insight for what technology or businesses will be like in the future, but guesses can be good.
