explanation for each part is important

25. A key input to the Define Activities process is the 027 a. Project management plan b. Project scope statement c. Project scope baseline d. Project charter 26. Unlike bar charts, milestone charts showa. Scheduled start or completion of major deliverables and key external interfaces b. Activity start and end dates of critical tasks c. Expected durations of the critical path d. Dependencies between complementary projects 27. Project managers should pay attention to critical and subcritical activities when evaluating project time performance. One way to do this is to analyze 10 subcritical paths in order of ascending float. This approach is part of a. Variance analysis b. Simulation c. Earned value management d. Trend analysis 28. An activity has an early start date of the 10th and a late start date of the 19th. The activity has a duration of four days. There are no non-workdays. From the information given, what can be concluded about the activity? a. Total float for the activity is nine days. b. The early finish date of the activity is the end of the day on the 14th. c. The late finish date is the 25th. d. The activity can be completed in two days if the resources devoted to are doubled. 29. In project development, schedule information, such as who will perform the work, where the work will be performed, activity type, and WBS classification, are examples of - a. Activity attributes b. Constraints c. Data in the WBS repository d. Refinements
