Answer:
The phrase indicating the advantage of matrix organizational structure is "makes it possible to focus on the coordination and integration between units".
The matrix structure is the structure in an organization in which relationships are not set up as hierarchy as traditional but in the form of a grid, which means that each employee would have dual responsibility as a functional and product development. Thanks for this structure, it could be possible for the company to integrate the objectives of the whole business with each functional department's objectives and within the internal system.
