Stage 1 Activity list

Stage 2 Draft logic diagram

Try drawing the draft logic diagram - is there a dummy? When you have prepared your diagram, follow the link below to see if it corresponds with ours.

Draft logic diagram - answer

Stage 3 Completed network, time and calculated.

Complete the network diagram showing durations and EST/LFT and, when you have completed the diagram, follow the link below to check your answer.

Network diagram - answer

Stage 4 Critical path

Now add the critical path to complete the network diagram and follow the link below to check your answer.

Critical path - answer

Stage 5 Float analysis

Prepare a table showing the free float and total float for the project. Once you have had completed this, follow the link below and see how you got on.
