2. Project Scheduling Procedure
• Determine the activities
• Determine duration of each activity
• Determine dependencies among activities---crucial for determining
project duration
• Prepare an activities profile
• Develop a network diagram
• Solve network: determine EST, EFT, LFT, LST
• State duration of project
• Determine critical path
• Compute float for each activity
• Prepare Project Schedule {Gantt/Bar chart}
