in systems design, the analyst specifies the detailed computer-based solution
vendor qualifications
in the procurement phase, which of the following is NOT a resource used to conduct research on technical alternatives? - vendor qualifications - internal standards - trade newspapers and - periodicals - information services - none of the above
false
modern structured design, information engineering, and object-oriented design are examples of process-driven approaches
false
prototyping, a modern engineering-based approach to design, is a sequential process that limits user participation in system design, so as to increase user morale and support for the project
false
rapid application development is a system approach that utilizes object-oriented modeling and joint requirement planning to develop an information system on time and within budget constraints
none of the above
structured design seeks to factor a program into the top-down hierarchy of modules that have the following properties: - highly cohesive and highly coupled - loosely structured and loosely cohesive - loosely cohesive and highly coupled - loosely cohesive and loosely coupled - none of the above
true
system design is also called physical design
false
the first task in the procurement phase is to solicit proposals or quotes from the vendors
false
the physical data flow diagram is used to establish the logical processes and data stores across a network
false
the primary tool of information is the structure chart
false
when modules are highly cohesive, each module should accomplish tightly related functions
structured techniques, joint application development techniques, object-oriented design techniques

none of the above
which of the following is NOT a disadvantage of prototyping? - errors can not be detected as easily when a prototype is developed - prototypes are a passive model of the system - end-users do not fully understand their requirements until they see them - none of the above
develop system models for each of the vendor's proposals
which of the following is NOT a task of the procurement phase? - evaluate and rank vendor proposals - validate vendor claims and performances - develop system models for each of the vendor's proposals - research technical criteria and options - none of the above
