Time to discover rework decreases over time in accordance with work by Lyneis, Cooper & Els : Strategic management of complex projects: a case study using system dynamics. System Dynamics Review Vol 17 No. 3, Fall 2001 V1.03 The concepts of tipping point and rework adding extra work are added as developed by Taylor & Ford in "Tipping point failure and robustness in single development projects" System Dynamics Review Vol 22 No 1, Spring 2006. The project suffers from a bad patch between weeks 20 and 50 V1.04 Schedule Pressure drives use of overtime. Whne the overtime factor gets above 1.5 we have to assume that extra staff are hired V1.05 Burnout as described by Jack Homer in "Worker burnout: a dynamic model with implications for prevention and control" System Dynamics Review No 1 Summer 1985.
