First Activities A and C, and then Activities B and D
Explanation:
An important part of schedule control is deciding if schedule variation requires corrective action. Activities on the critical path get first priority for immediate action. Larger delays on activities not on the critical path may not require immediate attention since they may not affect the overall project schedule. Hence, Ron will first deal with the delays on the critical path and then tackle the delays on the other paths. [PMBOK® Guide 6th edition, Page 210]
Finish-to-start with a 15-day lead
The landscaping work needs to start before completion of the office building, so it is a finish-to-start relationship. Since it needs to start 15 days before completion of the building, it requires a lead of 15 days. Hence, the answer is finish-to-start with a 15-day lead. [PMBOK® Guide 6th edition, Page 192]
Activity Duration Estimates should not include any lag or lead information.
Activity duration estimates are quantitative assessments of the likely work periods to complete an activity. They do not contain any lag or lead information. Lead and lags are determined during the Develop Schedule process when schedule network analysis is performed. [PMBOK® Guide 6th edition, Page 209]
Gantt chart
Such a chart is called a Gantt chart. This is a popular representation of project schedule information. Activity start dates, end dates, durations, dependencies, and milestones are easily depicted on this chart in a graphical manner. [PMBOK® Guide 6th edition, Page 217]
Activity B will be completed by the end of the day on Thursday, the 14th
Activity A has a duration of 4 days and completes by end of the day on Thursday, 7th. There is a 2-day lag, and since Saturday and Sunday are non-working, Activity B can begin only on Tuesday, 12th. Activity B has a duration of 3 days and completes by end of the day on Thursday, 14th. [PMBOK® Guide 6th edition, Page 192]
Sequence Activities
Sequence Activities is the process of identifying and documenting dependencies among schedule activities. [PMBOK® Guide 6th edition, Page 187]
Milestone chart
A milestone chart displays only the key deliverables and is simple and easy to understand. [PMBOK® Guide 6th edition, Page 218]
Crashing
Crashing is a technique that can be applied to compress the project schedule without changing the project scope. Another option is fast tracking. [PMBOK® Guide 6th edition, Page 215]
Gross value estimation
Analogous estimating is a gross value estimating technique. It is most reliable when the previous activities are similar in fact and not just in appearance, and the project team members preparing the estimates have the needed expertise. [PMBOK® Guide 6th edition, Page 200]
Rolling wave planning
In Rolling Wave Planning, the work to be accomplished in the near term is estimated in detail at a low level of the Work Breakdown Structure (WBS), while the work far in the future is estimated as WBS components that are at a relatively high level of the WBS. The work to be performed within another one or two reporting periods in the near future is planned in detail during the current period. [PMBOK® Guide 6th edition, Page 185]
