This treatise seeks to shine some light back on collaborative network-based planning by advocating the use of LDM (Logic Diagramming Method). LDM is a technique suitable for collaborative planning that is squarely within the reach of project stakeholders who are not necessarily trained schedulers. When used in conjunction with GPM(Graphical Planning Method)1, LDM allows effortless visualization of activity sequences and timing while also offering interrelationships between activities that are more intuitive and versatile for use by non-schedulers than those offered by PDM (Precedence Diagramming Method) or ADM (Arrow Diagramming Method). LDM is a recently unveiled activity-based networking method that modifies and extends ADM to permit PDM logic.
