Information Systems Analysis example essay topic

a. Information, because it is a report made up of data that when brought together becomes a useful document to tell the manager what parts are low in stock. b. Data, because that one customer alone is useless when its by itself. c. Data, again this is useless when just an order, would be info if it was a report of all the orders placed in a given time period. d. Information, because it is a document that presents statistics that can be used for other things. e. Information, because it takes every transaction and payment made to your credit card company and creates a report with Total Balances and interest rates.

As well as how much money is now due. 3. Sandra and Bob are Systems Analysts. Galen is the System Owner. The following people are all users: Monica, Steven, Steve, Dick, and Susan...

8. His current information system is really a personal information system because that is what is used in an office environment when described with word processing and spreadsheets for workers. These type of programs are used and designed to meet the needs of a single user and boost their productivity. To extend this to a true office information system, they can redesign it or modify it slightly to support not only individuals but work groups as well. This would include those workers not located in the same office.

Office automation systems are concerned with getting all relevant information to those who need it. This is accomplished through word processing, email, work group computing, work group scheduling, fax processing, imaging and electronic documents, and work flow management. 9. a. Transaction Processing Systems do bank deposits and withdrawals. b. Transaction Processing Systems would be used to print out a summary of cash total since that is the system that would keep track of money, like retail point of sale. c. Management Information Systems because they filter data to report exceptions, which is what checking to see if they have enough money is. d. Management Information Systems because they print sales reports which is similar to what taking money in and out of a bank is like. e.

Transaction Processing System generates those type of reports. f. Decision Support system because it will present him with a list of trends where he will then have to make a decision on which stock if any to buy. g. Expert system because the system is using A.I. to figure out the illness so the doctor doesn't have to spend time figuring it out when the computer can do it so much faster. h. Office automation and work group because they use email to communicate between an entire workgroup or office.

1) Systems analysis is a problem solving technique that decomposes a system into its component pieces for the purpose of studying how well those component parts work and interact to accomplish their purpose. Systems design is a complementary problem-solving technique that reassembles a systems component pieces back into a complete system-it is hoped an improved system. This may involve adding, deleting, and changing pieces relative to the original system. Information systems analysis is defined as those development phases in a project that primarily focus on the business problem, independent of any technology that can or will be used to implement a solution to that problem. 6) Object oriented analysis is a model driven technique that integrates Data and Process concerns into constructs called Objects. OO models are pictures that illustrate the systems objects from various perspectives such as structure and behavior.

Structured analysis is a model driven, Process-centered technique used to either analyze an existing system, define business requirements for a new system, or both. The models are pictures that illustrate the systems component pieces: processes and their associated inputs, outputs, and files. Information engineering is a model-driven and Data-Centered, but Process-sensitive technique to plan, analyze, and design information systems. IE models are pictures that illustrate and synchronize the system's data and processes.

9) Reverse engineering technology reads the program code for an existing system database, application program, and / or user interface and automatically generates the equivalent system model. It can be used by system analysts and users to provide a blueprint for a new and improved system. 11) Business Process Redesign is the application of systems analysis methods to the goal of dramatically changing and improving the fundamental business processes of an organization, independent of technology. 17) Cause and effect analysis is a technique in which problems are studied to determine their cause and effect. A risk of not performing this type of analysis is not correctly solving a problem or stating a valid solution.

You should truly analyze the problem before stating any solution. 19) An objective is a measure of success. It is something that you expect to achieve, if given sufficient resources. A constraint is something that will limit your flexibility in defining a solution to your objectives. Essentially, constraints cannot be changed. 25) Is the solution feasible?

That is the question asked in the design phase. IT is checked for Technical feasibility, operational feasibility, economic feasibility, and schedule feasibility. The information systems building blocks can serve as a useful framework for the decision analysis phase. The building blocks indicate our goal to develop a proposal that will fulfill requirements.
