| Question ID 22530 | Many IT projects experience problems because the development time and/or resource requirements are underestimated. Which of the following techniques would
provide the GREATEST assistance in developing an estimate of project duration?
|
| Option A | Function point analysis
|
| Option B | PERT chart
|
| Option C | Rapid application development
|
| Option D | Object-oriented system development
|
| Correct Answer | B |
Explanation A PERT chart will help determine project duration once all the activities and the work involved with those activities are known. Function point analysis is a technique for determining the size of a development task based on the number of function points. Function points are factors such as inputs, outputs, inquiries, logical internal files, etc. While this will help determine the size of individual activities, it will not assist in determining project duration since there are many overlapping tasks. Rapid application development is a methodology that enables organizations to develop strategically important systems faster while reducing development costs and maintaining quality, while object-oriented system development is the process of solution specification and modeling.
| Question ID 22531 | The reason for establishing a stop or freezing point on the design of a new system is to:
|
| Option A | prevent further changes to a project in process.
|
| Option B | indicate the point at which the design is to be completed.
|
| Option C | require that changes after that point be evaluated for cost-effectiveness.
|
| Option D | provide the project management team with more control over the project design.
|
| Correct Answer | C |
Explanation Projects often have a tendency to expand, especially during the requirements definition phase. This expansion often grows to a point where the originally anticipated cost-benefits are diminished because the cost of the project has increased. When this occurs, it is recommended that the project be stopped or frozen to allow a review of all of the cost-benefits and the payback period.
