Unified and aligned working methods are needed. Project alignment is the process of ensuring that key stakeholders share a common understanding of the project mission, goals, objectives, tactics, work processes and plans and have the required competences and skills. Based on current advances in the area of collaborative networked organizations, project management and Internet web 2.0 technologies, the authors have identified further needs and opportunities for development in the area of Collaborative Project Management. The Project Alignment Booster is a set of software services used to promote collaborative project management. The tool has been developed to suit industrial requirements in the area of large and complicated engineering project management, The paper reports the results of developing a toolkit to support collaborative project alignment.展开更多
