Studies of New Product Development Suggest Four Main Types of Team

Studies of new product development suggest four main types of team structure which of the following is not a valid description?

A) Functional structure - a traditional hierarchical structure where communication between functional areas is largely handled by function managers and according to standard and codified procedures.
B) Heavyweight product manager structure - essentially a matrix structure led by a product (project) manager with extensive influence over the functional personnel involved but also in strategic directions of the contributing areas critical to the project.By its nature this structure carries considerable organisational authority.
C) Lightweight product manager structure - a project-based structure but where a project manager provides an over-arching functional expertise.
D) Project execution teams - a full-time project team where functional staff leave their areas to work on the project, under project leader direction.
