What is the competitive advantage for an information system?

It is not a competitive advantage any longer. It is a matter of survival. The competitive advantage ended in the 70's. A modern enterprise can not be properly managed or run without an information system. The days of the rooms full of people with green eye shades is over.  Even individuals rely on information systems today. Quicken, MS Money, spread sheets. I have a gross of spread sheets. \n\nLet us take for example of just one business, the grocery store. Actually, today it is called the supermarket.  30 years ago, they had scores of clerks stamping prices on cans of beans, etc. Then they had scores of clerks keying those prices into cash resisters and other scores of clerks going through the isles trying to determine what they needed to restock. Then they had scores of clerks typing up purchase orders for more beans. Informations systems have eliminated all of that. The bar code on the product, tells the information system the product that was just bought. The information system calculates the price, deducts the item from inventory, and checks against the reorder point, and if that is reached issues an order for more of that item from the vendor and transmits the order to the vendors computer. \n\nDo you think that a company such as Walmart could even exist today without information systems?

Information technology (IT, also known as Information and Communication(s) Technology (ICT) and Infocomm, especially in Asia) is a broad subject concerned with technology and other aspects of managing and processing information, especially in large organizations.\n\nIn particular, IT deals with the use of electronic computers and computer software to convert, store, protect, process, transmit, and retrieve information. For that reason, computer professionals are often called IT specialists, and the division of a company or university that deals with software technology is often called the IT department. Other names for the latter are information services (IS) or management information services (MIS), managed service providers (MSP).\n\nIT (information technology) is a term that encompasses all forms of technology used to create, store, exchange, and use information in its various forms (business data, voice conversations, still images, motion pictures, multimedia presentations, and other forms, including those not yet conceived). It's a convenient term for including both telephony and computer technology in the same word. It is the technology that is driving what has often been called "the information revolution."

Information Systems.\n\nComputer Science has more to do with programming and such.  Information systems is more about using software tools effectively.  The latter is more likely of benefit to a biologist.

Computer models demonstrate that humans are by their nature competitive, but that cooperation provides a distinct competitive advantage in competitive environments.  So we can safely assume that we cooperate only so far as we perceive it to give us a competitive edge.  Society is a construct of information based on these cooperative agreements.  The information that supports cooperative advantage survive on, the ones that don't fade away.

Competitive advantage comes from being vertically integrated, having brand recognition, and sufficient size to fund future development.\n\nCost advantage also may come from being vertically integrated.  They also may have cost advantage if they refine in newer plants using newer technology.  Newer plants extract more high value products at a relatively lower cost.

They can be as involved, complex, or simple as the company and setting.  A medium-sized information technology (IT) shop, office, or department will have functional positions based on what they need to provide for the computer users.  There will be an IT director or senior boss responsible for the various components.  There will likely be a computer on every information worker's desk and those will likely be networked together, a place for a network administrator to see that everyone stays connected.  With computers there are machines and connections to establish and maintain and the software that does the work on those machines.  Your senior technologist is likely the guy in charge of the machinery, the actual computers, printers, servers, modems, and cabling.  Your systems analyst is likely the person who makes sure that the computer programs that process the sales, track the inventory, and keep the books is working together correctly.  The IT director is often, but not always, the one who planned the whole process in a new company, but anyway an information architect is the person who maps out who needs to know what and how to get it to them.  This includes plans for growth in the company as well as planning for new technologies.  The help desk is merely someone who has a basic knowledge of the whole system in order to answer questions or ask questions that will be useful for the systems analyst or senior technologist to figure out what is broke and what they need to do to fix it.   \n\nI've done a bit of most of these, and one of the most fun moments was when a customer in a distant town insisted I drop what I was doing and fix her computer because it wouldn't start.  I was due in a few minutes for a planning meeting with a small municipality over their accounting package.  After listening to her, I asked her to first check that all the cables, particularly power cables were connected and plugged in.  She was incensed!  I reminded her of our hourly rate and how long it would take me to get there and suggested she check those again and call me back in a few minutes.  She did and I didn't need to go, the computer was unplugged.  Most problems are highly technical and need other things, like a signal meter on some cables as has happened recently to me.  But many are simple and a moderately capable person who has the patience to listen can save the high-dollar guys a lot of wasted time.

pick a company - lets say a shoe store. use a paragraph telling what goes on in a shoe store - keeping an inventory -making sails - keeping books - paying staff etc. Then show how each of these activities could be improved by the use of a computer - speed - accuracy - ability to handle large amounts of data. Then finish it by talking about how a relational data base like Access would handle all of it.

Sustainable competitive advantage is a way of saying an investor's long-term investment matches a companies long-term position.  By considering whether a position is sustainable, strategic theory asks a person to consider the five forces of strategic position and see what's likely going to be a strong foundation.  \n\nBecause strategy is irreversible by definition, it ought to be created with utmost care and conviction.  \n\nExamples of sustainable competitive advantage may be:\n  -- Google's market position\n  -- IDEO's innovation model\n  -- GE's #1 or #2 position in every market they compete in\n      -- or their six-sigma process\n  -- Union Pacific's control of rights of way in urban areas\n  -- NASA's experience and technology set in space exploration\n\nMichael Porter's Competitive Advantage is still the seminal work on the whole area of thought.  You'll also find good information published by the big-three strategy consultancies: McKinsey, Bain, and Boston Consulting Group.  Finally, Harvard Business Press puts out the best strategy case studies and articles in the industry.\n\nIncidentally, Boston Consulting Group basically invented strategy when they first studies learning curves in the aviation industry a very long time ago.  They discovered that the learning curve was 1) real, 2) predictable, and 3) sustainable.  So, if it cost me $5 to manufacture an airplane part for the first part, how long until it cost only 50 cents, and how should I set prices so that others can't afford to come into the market and compete with me?

http://en.wikipedia.org/wiki/Management_information_systems\n\nDid a search on Google and couldn't find any useful on CIS just courses\n\n"The CIS program stresses management and business legacy systems (mainframes, COBOL, RPG, and so on) plus application development for Windows environments (Visual C++ and Visual Basic, spreadsheets, etc.), primarily for large management information systems and database systems (including accounting, inventory, payroll, personnel, and sales)."

All medium to large organisations depend on Information technology For their continued survival. Consider organisations like British Gas, British Telecom, the Power and Water companies having to manually calculate, millions of customer bills every month or quarter! Clearly the clerical effort involved would make it difficult if not impossible for the organisation to make a profit. Similar arguments apply to many other organisations such as the high street banks, central and local government. A recent article in the Daily Telegraph IT supplement suggested that many large organisations could last no longer than 24 hours without IT support! There should be little wonder that attitudes to the development of information systems have changed over the years from an ad hoc almost cavalier approach to a professionally managed, disciplined, planned, engineering approach.\n\nFor more information on this topic, please go to http://www.comp.glam.ac.uk/pages/staff/tdhutchings/chapter1.html.
