Project Planning & Scheduling
Critical Path Method
Provides a structured approach to project planning through a network diagram that links activities in a way that provides a logical relationship with them
What is an activity?
Referred to as a task & defined as a piece of work that consumes time.
The Network Diagram
A sequence of steps (activities), commonly represented by blocks, that are linked together in the logical sequence they need to be carried out.
To know the activities involved in making the cup of tea & how they all fit together in a logical sequence
The logic links in other words what activities should we start with & then finish with/even how activities are connected
Start/Start (SS) - when one activity starts, another independent activity must start.
Start/ Finish(SS) with a lag - when one activity starts, another must finish (this relationship is not at intuitive or useful as the other relationships
Finish/Finish (FF) - two activities must finish at the same time.
Finish/ Start (FS) with a lag - the succeeding activity must start some defined time after the preceding activity has finished.
Activity Logic Table:
Used by project teams to list activities in logical sequence as well as linking the logical sequence
Determines what task must be done prior to the current task & what tasks may be done at the same time.
Developing a schedule
Involves determining the timing of work activities identified by the planning process and results in a project schedule.
Represents sequencing and phasing of individual activities required to complete the work.
Is a timetable for the plan and cannot be established until the network based plan has been created
Used to communicate schedule info to all stakeholders
