Scheduling Methodologies and Approaches


Location:  PMKI > Project Controls and Scheduling > Scheduling Methodologies and Approaches. 

This subject looks at the wide range of scheduling methodologies and approaches to improving CPM scheduling currently available. Traditional ‘critical path’ scheduling is only one of the ways to develop a useful and effective schedule, and in many situations it is far from optimal.

  • Scheduling Methodologies
    • 5-STEPS, the ‘5 Steps To Ensure Project Success’ methodology is a proven process designed to focus the thinking of key Stakeholders onto the parameters required to achieve a successful project outcome. 5-STEPS uses the development of the schedule as a central plank in its approach to developing an effective project team and fostering positive stakeholder involvement.

    • Beeline Diagramming Method (BDM) Beeline represents the overlapping relationship between two consecutive tasks by the shortest straight line (the beeline). BDM connects any point in the predecessor to any point in the successor - www.mosaicprojects.com.au/PDF/Beeline_Diagramming.pdf 
       
    • Chronographic Model uses the concept of internal divisions and internal measurement as a function of production - www.mosaicprojects.com.au/PDF/Chronographic_diagramming_method.pdf 
          
    • Critical Chain is a method of planning and managing projects that puts the main emphasis on the resources required to execute project tasks - WP1050 Critical Chain  
       
    • Earned Durations (ED) / Count the Squares (CTS) is a method of assessing schedule performance based on the comparing the duration of activities 'as-planned' and accomplished. In the 1970s CTS was used where each day of an activities duration was counted as ‘1’ and the cumulative planned days was compared to the cumulative actual days work accomplished. ED modifies this basic process by adjusting the 'earned duration' for each activity based on the current expected duration. The fundamental weakness in this approach is its assumption that one days work on one activity in a barchart is equivalent to any other day's work on any other activity, whereas the the resources assigned to one activity in a may be 1 person per day and another 15 people per day.
       
    • Earned Schedule (ES) adapts traditional Earned Value data to provide a reliable prediction of a project's expected completion date. ES overcomes the limitations in ED/CTS by using the value of the work accomplished as a reasonable proxy for the resources being used to accomplish the work.  See: http://www.earnedschedule.com/  
       
    • Line of Balance (LOB) is a method of showing the repetitive work that may exist in a project as a single line on a graph - WP1021 Line of Balance  
       
    • Momentology focuses on measuring the momentum of work on the project. Each section of a project has its momentum as does the overall project - WP1036 Momentology 
        
    • Multiple Activity Charts (or Multi-Activity Charts) are a very useful tool for understanding the flow of work in a cyclical process and as a consequence understanding which resource is controlling the overall progress - WP1025 Multiple Activity Charts  
        
    • RD CPM™, The Relationship Diagramming variation of the Critical Path Method of schedule analysis developed by Fredric L. Plotnick - WP1035 Relationship Driven CPM
       
    • Rolling Wave Planning is the process of increasing the detail in a schedule as more information becomes available - WP1060 Rolling Wave Planning  
        
    • Schedule Density, similar to rolling wave planning but designed for modern software - WP1061 Schedule Density 
         
    • Timeboxing, is used to attempt to complete the defined amount of work in a fixed period - WP1020 Timeboxing    
       

  • Scheduling methodologies (White Papers)
    • WP: Relationship Driven CPM. The RDCPM® variation of the Critical Path Method of schedule analysis focuses on the reason for the relationship between activities and the reason for their overlap.    
    • WP: Momentology. Momentology uses the schedule to measure the momentum of work on the project. The loss of momentum is a reliable predictor of a delayed completion.   
    • WP: Critical Chain. CCPM is a method of planning and managing projects that puts the main emphasis on the utilisation of the resources required to execute project tasks.    
    • WP: Line of Balance. LOB is a method of showing the repetitive work that may exist in a project as a single line on a graph and shows the rate at which the work has to be undertaken to stay on schedule.    
    • WP: Multiple Activity Charts. Multiple Activity Charts show the flow of work within a cyclical process and as a consequence show which resource is controlling the overall progress of the work.  
    • WP: Timeboxing. Timeboxing is a simple process used to measure the complete of a defined amount of work in a fixed period, plus or minus an allowed variation (the 'time box').
