CPM Calculations || A+ Verified Solutions.

Forward Pass correct answers Method used to determine ES and EF times of activities, as well as minimum total project duration. It assumes all activities start and finish ASAP, and their following activities start immediately. What day should the CPM start? correct answers Day zero End of Day convention correct answers ES of an activity starts at the end of a previous work day Early Finish (EF) correct answers ES + Duration Early Start (ES) correct answers Earliest an activity can start based on the earliest an activity, or activities, preceding it finished. Early start when more than one activity precedes it? correct answers Highest EF of preceding activity. Early start (ES) of start to start (SS) relationship with predecessor correct answers ES(pre) + lag (if existent) Project Duration correct answers EF of the last activity in the project. Project duration with multiple last activities? correct answers Last activity with highest EF End node correct answers Node where all last activities feed to created as a good practice. It has an activity duration of zero. Often noted as a milestone activity such as Project Complete. Hammock Activity correct answers An activity that stretches between two or more activities and has a duration dependent upon the start and finish of activities it is connected to. It has default SS and FF relationships with connected activities. Can a hammock activity have lag? correct answers NO Backward Pass correct answers Method used to determine late start (LS) and early finish (EF) times of activities. It assumes all activities will finish and start as late as possible and that preceding activities will finish as late as possible (no lag). Where does the backward pass start? correct answers The last activity in the network. What is true about the last activity calculations? correct answers ES = LS, and EF = LF, zero float. Start to Start (StS) correct answers Relationships that can go on at the same time. Sometimes may require one activity start a little while after the start of the other activity.
