MIS Final Exam (A+ Guaranteed)
Series of well-defined phases performed in sequence that serves as framework for developing
system or project
- Each phase's output becomes the input for the next phase
- Suitable for an information system that needs to be designed from scratch correct answers
Systems development life cycle (SDLC)
What are the phases of the SDLC? correct answers planning, analysis, design, implementation,
maintenance
When dealing with Planning, systems designer must _____ the organization faces correct
answers define the problem
Assesses a system's costs and benefits
- Tangible development and operating costs for the system have to be itemized
- Tangible and intangible benefits have to be identified and measures correct answers Economic
feasibility
Whether the technology to support the new system is available or feasible to implement
- Organizations that lack the expertise, time, or personnel to implement the new system might
lack technical feasibility
- Steps should be taken to address shortcomings and consider the new system correct answers
Technical Feasibility
Measure of how well the proposed solution will work in the organization and how internal and
external customers will react to it
- Requires assessing the worth of implementing the information system correct answers
Operational Feasibility
Concerned with whether the new system can be completed on time
- Failure to deliver in time leads to loss of customers
- Problem can be minimized by using project management tools correct answers Scheduling
Feasibility
Concerned with legal issues. Addresses questions such as:
- Will the system violate any legal issues in the country where it will be used?
- Are there any political repercussions?
- Is there any conflict between the proposed system and legal requirements? correct answers
Legal Feasibility
The models created during the _____ phase of systems development life cycle (SDLC) constitute
the design specifications. correct answers Analysis
, Overview of the system, does not include hardware or software choices correct answers
Conceptual design
Makes conceptual design specific by indicating hardware and software correct answers Logical
design
Created for specific platforms correct answers Physical design
What kind of tools automate parts of the application development process that is helpful for
investigation and analysis in large-scale projects? correct answers Computer-Aided Systems
Engineering (CASE)
Old and new systems run simultaneously for a short time to ensure the new system work
correctly? correct answers Parallel conversion
As each module of the new system is converted, the corresponding part of the old system is
retired. This process continues until the entire system is operational correct answers Phased-in-
phased-out conversion
Old system is stopped and the new system is implemented correct answers Plunge conversion
(direct cutover)
Analyst introduces the system in a limited area of the organization and is implemented in the rest
of the organization in stages or all at once if the system works correctly correct answers Pilot
conversion
To help solve scheduling problems, plan and set goals, and highlight potential bottlenecks. And
project management software helps study cost, time, and impact of schedule changes correct
answers Tools and techniques
What does PERT stand for? correct answers Program Evaluation and Review Technique
What does CPM stand for? correct answers Critical Path Method
Constructed using the critical path
- Allows the systems analyst to monitor the progress of the project
- Helps detect delay in the daily operation of the project correct answers Gantt Chart
End users develop information systems with less or no formal assistance from the information
systems (IS) team
- use off-the-shelf software to produce custom-built applications
- helps reduce the backlog in producing information systems
- improves flexibility in responding to users' information needs correct answers Self-Sourcing
What are the disadvantages of Self-sourcing? correct answers 1. Possible misuse of computing
resources
