1.The_____________technique is used to estimate project duration when there is a high degree of uncertainty about the individual activity duration estimates. This technique uses 'probabilistic time estimates'--duration estimates based on using optimistic, most likely, and pessimistic estimates of activity durations rather than one specific or discrete duration estimate.

2.The essential inputs to the critical path method consist of: options 1.a flow chart of all activities involved in a task and directional arrows 2. a Gantt chart and a list of hard deadlines 3.a series of tasks and the costs involved in each task 4.a list of each activity, its expected duration, and any activities that immediately precede each activity

3.____________is a group meeting-based process for requirements collection; this is usually conducted in a big conference room equipped with technology devices to support the meeting.

4.The_____________________provides a way to easily identify the fastest a project can be completed, given that the estimated durations of activities are accurate:

5.Which of the following is true for prototyping? options 1.This approach permits formation of a model of the new system that can be evolved and modified in an iterative fashion as systems analysts and designers better know end users' needs. 2.It is synonymous with the maintenance phase of the SDLC. 3.It is also known as end-user development 4. It does not consider user requirements for the system 5.None of the above are correct

6.Which of the following abilities are critical for a systems analyst? options 1.Must have an engineering degree. 2. Creativity in the design and modification of systems and ability to work with and through people. 3.Must know how to negotiate with software vendors. 4.Must speak different foreign languages.

7.Which of the following is not relevant to determining technical feasibility of a system solution? options 1.Can the work be done with existing equipment? 2.Can the work be done with existing personnel? 3. Should the firm consider connecting its network system with that of another firm? 4.Will existing software support the desired outcome?

8. Which of the following is not relevant to determining operational feasibility of a system solution? options 1.Will the new system improve the firm's brand image? 2.Will there be resistance from end users? 3.Does the system have the support of top management? 4.Can the new system be incorporated into the organization successfully if implemented?

9.Which of the following is not relevant to determining economic feasibility of a system solution? options 1.Are there quantifiable benefits when compared with the costs that need to be incurred? 2.Are alternative sources of funding available if needed? 3.Is the vendor of the proposed solution well known and reliable? 4.All of these are correct
