The terms used in a fuzzy logic system to describe imprecise states or conditions are referred to as

A) neural networks.
B) membership functions.
C) inference engines.
D) taxonomies.
E) tags.

Question 2

You are consulting for the information technology division of a state university to guide and facilitate the design of a new system for handling college applications, which has previously been handled entirely with a paper-based process.

They would like to set up a system by which prospective students can apply online. Describe in detail their first steps and any studies they should perform before designing the new information system.

Answer to Question 1

B

Answer to Question 2

Student answers will vary, but should include an understanding of the first step of systems developmentsystems analysis, along with feasibility studies and determining information requirements. An example answer is:
The college will need to perform systems analysis. This consists of defining the problem, identifying its causes, specifying the solution, identifying the information requirements. It also includes identifying the primary owners and users of data along with existing hardware and software, the problems of existing systems, examining documents, work papers, and procedures; observing system operations; and interviewing key users of the systems. The systems analysis would include a feasibility study to determine whether that solution was feasible, or achievable, from a financial, technical, and organizational standpoint. The feasibility study would determine whether the proposed system was a good investment, whether the technology needed for the system was available and could be handled by the firm's information systems specialists, and whether the organization could handle the changes introduced by the system. They should identify several alternative solutions that the organization can pursue. The process then assesses the feasibility of each.
A written systems proposal report describes the costs and benefits, advantages and disadvantages of each alternative. It is up to management to determine which mix of costs, benefits, technical features, and organizational impacts represents the most desirable alternative. They will also need to define the specific information requirements that must be met by the system solution selected. This involves identifying who needs what information, where, when, and how. Requirements analysis carefully defines the objectives of the new or modified system and develops a detailed description of the functions that the new system must perform.
