Consider a scenario where a task is dependent on another task being started not necessarily completed . For example a project may depend on a task being started and 25% being completed before the group could start their portion of the project. Do you think this situation occurs frequently in system analysis projects

- Suppose you are the project manager for the following project: First,draw a network diagram for the project. Determine the critical path andslack times for all of the tasks. This completes your plan for the projectschedule. During project execution, you become aware of the need tochange the duration of Task 4 to five days.Meanwhile, Task 3 has been finished one day early, so it only took one day to do. What, ifany, effects do these changes have on your project?

- A project has three sequences of activities (paths), two of which are critical. The critical paths of this project can be characterized in the following way: a. The slack times for each task in the entire project are zero. b. The chain of activities (from start to finish) that has the largest sum of activity durations. c. The early start date and early finish date are always the same for each activity on the critical path. d. To reduce the project duration, you must reduce the slack time of a task on the critical path. e. None of the above are correct.arrow_forwardBoth architectural and non-architectural maps of a project should be created for optimal comprehension.what effect it will have on the final result.arrow_forwardBoth architectural and non-architectural maps of a project should be created for optimal comprehension. what effect it will have on the final result.arrow_forward
