Process modeling and simulation remains an essential tool for performance support professionals - and, unfortunately, they are seldom used. Sketching a static process flow as part of user task analysis does not get to the root of process dynamics and the complexities that knowledge workers must deal with. SimCad is a best-of-breed process simulator. According to CreateASoft: "SimCad Pro 6.3 expands the existing feature list by adding the ability to create a dynamic value stream map from the original process map with ease. Analysis of the value stream map can then be performed by running different product mixes and what-if scenarios to detect any potential issues with the new designs. Additional features include an extensive VB scripting interface that allows SimCad to interface with existing ERP or MRP systems and provide a live view of the manufacturing environment; a forecasting operation predicts potential future problems and alerts the user of such conditions."
