The lack of true leadership and technology insight brings the best above in people involved in projects. I consider the team members fully capable and as such can benefit from a great deal of self-steering. Modern approaches like Agile and Scrum put planning and execution back in the hands of the team.
I, as the project manager, am much more involved in the technical discussions and am the catalyst for continues improvement and also the partner of the business. Tasks that I performe can lie on both sides of the spectrum: as a scrum master role and the product owner role. This fusion of business and technology is where I as the project manager take center stage by having experience in both world and connecting these two to fuse them to become one.
