Marsha Marsha Marsha

There is a lot to mock about The Brady Show, but if you were raised in the seventies you probably viewed most of the episodes more than once.  (If you have never seen the show, then you really didn’t miss much except a lot of homey corniness, bad and constantly changing hairstyles and an earworm of an opening jingle.)
For those of you who have seen the show, you probably remember the episode where Jan was jealous of her sister and screamed out “Marsha! Marsha! Marsha!” to highlight the fact that everything in the Brady household seemed to revolve around her older sister Marsha.[1] 
If you are a risk manager of a certain level of experience and competence you are likely to exclaim in a similar fashion and with a similar level of envy and exasperation “Data! Data! Data!”.
Jan’s parents, like all good parents, loved each of their children through thick and thin.  However, in any complex situation there are times when things are “thick” and times when things are “thin”.  Just as one child is not superior to another child, one form of risk management is not exclusively nor inherently better than another.
Risk management by data has its place, but it should not be to the exclusion of all other methods of assessing and responding to risk.  Just as a parent does not want to be seen as catering to the needs of one child to the exclusion of the other children, risk management should not focus exclusively on risk control by data metrics.  There is a case to be made that some of the most important aspects of risk management are not measurable – even conceptually.
