Compare and contrast the four basic system conversation strategies.
This question asks for a comparison and contrast of the four basic system conversation strategies.
Describe several evaluation factors that should be considered in evaluating the acquisition of h.
The question asks for a description of several evaluation factors that should be considered in evaluating the acquisition of h.
Match the following IS development cycle steps with their descriptions:
Analysis = Identifying the problem and obtaining the requirements Design = Creating the structure and architecture of the system Implementation = Putting the designed system into action Maintenance = Making changes and improvements to the system after it's in use
Match the following project management activities with their descriptions:
Planning = Setting the goals, defining the scope, and creating a schedule Organizing = Assigning tasks, assembling resources, and establishing procedures Leading = Motivating and directing the project team to achieve the goals Controlling = Monitoring progress, identifying variances, and taking corrective actions
Match the following system conversation strategies with their descriptions:
Direct = Switching from the old system to the new one at an appointed time Parallel = Running the old and new systems simultaneously for a period of time Pilot = Implementing the new system in just one part of the organization Phased = Gradually replacing the old system with the new one in stages
Match the following IS acquisition evaluation factors with their descriptions:
Cost = The financial investment required for the acquisition Compatibility = The ability of the new system to work with existing hardware and software Support = The availability of assistance and maintenance for the acquired system Scalability = The capability of the system to handle increased workloads as the organization grows
Match the following prototyping benefits with their explanations:
Improved User Involvement = Users can provide feedback and suggestions during development Reduced Development Time = Quick creation of prototype to gather user feedback early in the process Improved System Quality = Identification of design flaws and requirements issues early on Reduced Risk of Project Failure = Early identification of potential problems and user acceptance issues
