Lecture 3. Scheduling Flashcards
Why plan?
Time management. Communication tool, forecasting, controlling, monitoring and benchmarking. Allows for the considered adjustment of scarce resources. Contractual obligation.
What is The Project Charter?
High level statement of what is to be done and the boundaries to a project.
What is scope management? (steps)
Translation of project charter into detailed documentation which becomes a project brief. (drawings, specifications and quantities).
Method statements then created (how product will assemble).
Project can be planned, subdividing the scope of work into manageable packages. (work breakdown structure)
Planning of time, cost labour resources can then be undertaken using suitable planning tool.
What is ‘work breakdown structure’?
Project planned, subdividing the scope of work into manageable packages.
Why is the project dividing into activities (WBS)?
For cost estimation and scheduling.
Why project control?
Project team should be able to ask at any time where they are and how do they get there.
Essence of project management. (4 of them)
- Work breakdown into tasks
- Estimate duration of each task
- Optimise sequence of tasks
- Reconcile the analysis with the actual availability of resources.
What are the requirements of an effective planning system? (6 of them)
- Sensible and realistic
- Content must be relevant
- Must be interrogative and interactive
- Must be flexible
- System should be dynamic
- Must communicate information clearly
Tools for Network Analysis and Gantt Charts?
- Calendars
- Histograms
- Gantt Charts
- Network analysis (crit path method or precedence diagrams)
- Line of balance
- Last planner
- Theory of constraints

Where does late finish go in an activity node?
Bottom right.
Where does float go in an activity node?
Mid left.
Where does early finish go in an activity node?
Top right.
Where does Late start go in an activity node?
Bottom left.
Where does duration go in an activity node?
Mid right.
Where does activity number and description go in an activity node?
Mid mid.
What is the critical path?
Series of activities that have zero float.
What is the activity float?
Measure of an activities flexibility.
What is free float?
Float an individual activity can use up without effecting the early start of the next activity.
What is the total float?
The float shared with other activities.
What is the Precedence Diagram Method (PDM)?
Estimate the duration of each activity.
Initial take off should be unconstrained.
Establish relations between activities.
What are the precedence relationships?
Finish to start - FS Start to start - SS Finish to finish - FF Lag Milestones: 0 duration
What is finish to start?
Activity B cannot start until activity A has finished.
What is start to start?
Activity B cannot start until activity A has started.
What is finish to finish?
Activity B cannot finish until activity A has finished.
What is early start?
Earliest time an activity can start.
What is early finish?
Earliest time an activity can finish.
What is late start?
Latest start an activity can start without project delay.
What is late finish?
Latest time an activity can finish without project delay.
Early start + duration =
Early finish.
Early finish (predecessor) =
Early start (successor)
Late finish - duration =
Late start.
Late finish (predecessor) =
Late start (successor)
