The purpose of this article is to develop a process model of robust strategy by using Interpretive structural modeling. Robust strategies are capable of performing well in a variety of possible future environments. This process model is combination of other techniques. The techniques are obust ecision making takeholder Analysis A, Assumption ased Planning A P, Failure ode and Effect Analysis F EA, Fault Tree Analysis FTA , Potential Problem analysis PPA, olution Effect analysis EA, Change Impact Analysis, ncertainty ensitive Analysis P, and cenario based planning P. Critical comparative review of techniques demonstrated that these techniques are not complete, but provide a good starting point. In this article, these techniques were combined together in a systematic manner by using Interpretive tructural odeling. The resultant prescriptive process model of robust strategy has sub processes. The sequence of sub processes was specified and also the input, output, and feedback of each of them were obtained.
