Effect of Team Replacement Events on Risk Dormancy: Dynamic Probability Model

Farag Emad and Ingman Dov

Today’s industrial organizations use multi-team (MT) efforts to achieve effective performance and enhance the quality of their work. MT work is characterized by multiple teams acting concurrently or sequentially to produce a specific outcome over time. This outcome could be in many cases accomplished only by team replacement (TR). MT's may also generate risks. These risks might not cause damage to the team right away, but might possibly create risk dormancy (RD). TR is a crucial interface between teams, and therefore successful TR should consider a set of risk evaluation procedures to avoid accidents. The risks include, but might not be limited to, hazard identification, alert from each other's hazardous activities, etc. The emphasis of this analysis is on the TR, its role, significance and attributes, from the standpoint of risk evaluation and detection, and its effect on RD. A new probabilistic model is suggested. The model is intended to predict the role of TR over the entire RD range. The model can be used to manage the RD as far as TR is concerned. The analysis is, in effect, an extension of the authors' earlier research on the problem of the MT risk dormancy (MTRD).
