2. Intelligence and design are two stages in the Decision making and problem solving models. Intelligence is the first stage while design is the second stage. During the intelligence stage potential problems or opportunities are identified and define. During the design stage, alternative solutions to the problems identified in the intelligence …show more content…
Organizations should develop an expert system if it can do any of the following: provide a high potential payoff or significantly reduce downside risk; capture and preserve irreplaceable human expertise; solve a problem that is not easily solved using traditional programming techniques; develop a system more consistent than human experts; provide expertise needed at a number of locations at the same time or in a hostile environment that is dangerous to human health; provide expertise that is expensive or rare; develop a solution faster than human experts can; provide expertise needed for training and development to share the wisdom and experience of human experts with many people.
10. Fuzzy logic is knowledge and relationships that are not precise or exact. Fuzzy logical allows shades of gray, or what is known as "fuzzy sets." Fuzzy logic rules help computers evaluate the imperfect or imprecise conditions they encounter and make educated guesses based on the probability of correctness of the decision.
11. Informatics is a specialized system that combines traditional disciplines, such as science and medicine, with computer systems and technology. A few examples include: Bioinformatics, computational biology, and medical …show more content…
Information system stakeholders are people who, either themselves or through the area of the organization they represent, ultimately benefit from the systems development project.
14. Technical, economic, legal, operational and schedule.
15. The purpose of system analysis is to determine what the information system must do to solve a problem by studying existing systems and work processes to indentify strengths, weaknesses, and opportunities for improvement.
16. Prototyping is an alternative approach to systems development that takes an iterative approach to the systems development process.
17. The steps in Object-oriented systems development are: Identifying potential problems and opportunities within the organization that would be appropriate for the OO approach; defining what kind of system users require; designing the system; programming or modifying modules; evaluation by users; periodic review and modification.
18. The reason for program maintenance is to enhance the system to make it more useful in achieving user and organizational goals. Maintenance also ensures the system operates correctly.
19. A program that prevents computer waste and mistakes should: establish policies and procedures; implements policies and procedures; monitor policies and procedures; review policies and
