Concept explainers
A.
Interpretation: A network diagram depicting the work flow of the project is to be drawn.
Concept Introduction: Network diagram is a graphical representation of tasks and events happening in a project. It depicts the work flow and is used to compute the total duration of the project.
B.
Interpretation: The critical path is to be identified by computing the earliest and the latest start and finish times.

C.
Interpretation: A Gantt chart of the
Concept Introduction:Gantt chart is a project management tool that is a type of bar chart. It depicts the project schedule and is used for resource allocation.
D.
Interpretation: The group of activities that have to be completed by day 60 so as to ensure that the project will be completed without any delay is to be identified.

- the manpower requirement for each activity in a construction project is given in the attached table. All activities are scheduled to start at it's earliest Start times (1) draw the project network and determine the critical path and durationarrow_forwardDave Fletcher was able to determine the activity times for constructing his laser scanning machine. Fletcher would like to determine ES, EF, LS, LF, and slack for each activity. The total project completion time and the critical path should also be determined.
