In management and organisational theory, there are at least three principle dysfunctional behaviour present within all groups. Whether one calls the group Umno proper, or Wanita Umno, or the nation state, theorists would argue that one can observe similar dysfunctional decision-making behaviour in all groups most of the time.
The first kind of dysfunctional behaviour is called "Group Think" made famous by Irving Janis in 1972 reflecting on the Bay of Pigs incident involving President JFK, and other similar incidents. In Group Think, the experts or the involved team are extremely convinced that they cannot and will not make a wrong decision.
