I made the decision recently with Enterra to cease being even a halftime employee as of 1 July (I had been a 1/2 to 2/3rd employee during the great majority of my time with the company). This move was in keeping with the company's evolution over the past couple of years: by expanding so concretely into supply chain management, there was simply less for me to do in the position, which largely had me searching for the right businesses in which to best exploit Enterra's technologies. That search now over, I move on to other opportunities.
My six years at Enterra were quite fascinating and I greatly enjoyed helping build the company.
