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.
