Correct Answer: CA matrix organization is characterized by employees from different functional departments working together under one project manager. This structure allows for resource-sharing across projects and departments, which fits the description of a software development firm where team members from multiple departments report to a single project manager. Functional departmentalization involves segregating jobs by functions, and product departmentalization focuses on product lines. A divisional organization, on the other hand, is based on semi-autonomous divisions. Hence, the best fit is a matrix organization.
