CPM

CPM networking can be done manually in small projects with a few hundred activities, and computer based in  large projects with thousands of activities to be planned individually and with total integration. 

A detailed network by CPM can be developed only after three things are done as the first step. They are as follows : 

• Definition of the project scope in full 
• Perspiration of WBS 
• Listing of activities, down to the bottom level elements which have to be handled separately and have an influence on the completion of the project. 

The subsequent steps are as follows : 

• Arrange the activities in logical sequence and number them in line with the codification scheme developed. 
• Link activists in a network form with reference to logical relation and dependency, using lines and circles. 
• identify key activities and milestone events and snack them prominently 
• Place the sequential numbers of events and milestones in the circles. 
• Ensure that either the activity descriptions are written on the lines or there is a list of them whose code numbers are written on the lines. 
• Estimate time duration, start-fish times and floats for all activities  ,and milestones and enter them in the network. 
• Mark the critical path. 
• Though the oversteps you have made a draft summary network or a master network plan ready. Check the draft to ensure perfect logical relation, accuracy in time estimates and selection of milestones, and technical and logical correctness in the determination of critical path. 
• Redraw the network's fair copy in a calendar frame or a project time frame.
• From the finally drawn summary network, make detailed subsets tor adherent work segments or stages and fragments for lower level activities and short-term targets. Make out detailed schedule of resources in a bar chart or tabular chart tallying with the CPM network.
