I agree with smk45 that matrix organizational structure is the most ideal for collaboration projects. Staffers in a matrix organizational structure report to a product line manager and a functional manager who determines the direction on product offerings and help with skills, review and prioritization of work respectively. In collaborative projects, more often than not, resources are poorly utilized. Matrix organizational structure address this challenge as it allows equipment and experts to be shared across projects. Moreover, all projects and products are formally coordinated across various departments in matrix structure, making this structure the most suitable for collaboration projects.
