I've been reading and linking to Subbu Allamaraju's blog for more than a decade. The Value is in Dealing with the Messy Stuff is a post about learning to see messy problems as opportunities and learning to see silos as tools for solving messy problems. Mapbox, where I work, is exactly at the stage where this mindset is helpful. Subbu uses team and silo almost interchangeably, but I don't think it's intended that the reader equate them. A team is part of an organization's model of how problems get solved and silos are part of the observed reality of how problems get solved.
