Roughly half of all project managers have to lead customer projects as profit centers on contractor side with two big objectives: making the customer happy and bringing money home. Customer projects are a high-risk business on both sides, customers and contractors, but the dynamics of this business have so far been mostly ignored in literature. The book is intended to fill this gap. The book helps project managers better understand the dynamics of customer projects under contract from business development through handover and find solutions for common problems. A central aspect is international contract laws, an often underestimated factor in projects. Oliver F.
