I have worked within both divisional: product-based and matrix organization. I would still consider the matrix to be organization structure of choice.In my experience within product-based, there were always issues regarding statuses or approvals from other team, communication was often lost, and as a result this hindered meeting timeline objectives. In my opinion, this option offers more flexibility and exposure to cross functional teams, in other words it enables the team member’s exposure to various areas within this organization, and lastly the decision making is more balanced, since there are more than two chains of command.
