Before the beggining of RDM module I had a clear engeneering understanding of what acually robustnes is in technical systems: it is an ability of system to save the given inventory of stability in case of variations of its parameters caused by change of loading the object by internal or external environment. By usining Nyquist criterion it was easy to come up with a decision about wheather the system is robust or not.
This module showed that it is impossible to use such type of approach for robust desicion making in business systems, where much more factors have to be considered (especially human factor). During monday session I totally understood how bias is human factor and to what extent it can influence to the whole system to be robust or not. I is also interesting to mention that human factor can be devided into several parts like individual bias, group thinking bias and company level bias. All of them can strongly influence on the level of system (decision making) robustness.
To avoid that people designed some methodologies that can help businesses in making such kind of decisions according to particular consitions. Still there is a problem of understanding WHAT ACTUALLY THE CONDITIONS ARE. Gathering appropriate for the conditions information and getting rid of inrellevant is a tough process (need also to be robust).
So what I really understood, the there is only one tool that works in such type of systems - EXPERIENCE. Going thruogh decision making time after time can teach us how to reach the extent of making robust decisions.
