Serial Entrepreneur and Yet Another Agile Coach...I start a company, it fails, I go back to coaching. [repeat]. I've been designing systems (telephone switches, railway signalling) and managing systems development since the days of Fortran and 5 micron CMOS. Over the years I learned the hard way the key determinant of project success was how well people worked together. Somewhere along the line I got a crazy idea to get a PhD...perhaps that should be a test for insanity.
