Terrific post here from @ginidietrich on silos inside the C suite. Seems to me that the two greatest enemies of everything in 2012 are silos and groupthink. They do of course go together, as when we climb out of them to do allegedly creative strategy together the problems of salience et al. emerge.
The situation of the C suite atop the traditional hierarchies of a functional organization is in fact a subset of the problems we have in handling knowledge when data has exploded and the age of expertise is in a significant respect over. It’s those who bridge knowledge silos who shape what comes next. Modeling and applying this in our organizations, one would have thought, was 101.
