Final answer:
In project management, a weak matrix has limited project manager authority with functional managers leading, while a strong matrix gives more power and autonomy to the project manager.
Step-by-step explanation:
The difference between a weak matrix and a strong matrix in project management refers to the structure of authority and the power distribution within an organization. A weak matrix is a scenario where functional managers have predominant authority and the project manager has limited power and often acts more as a project coordinator. In contrast, a strong matrix organization, the project manager has greater authority and power, holding primary responsibility for the project. This hierarchy affects resource allocation, decision-making, and the overall approach to managing the project's lifecycle.
Key Differences:
- In a weak matrix, the role of the project manager is more like that of a coordinator or expeditor, whereas, in a strong matrix, the project manager has a role similar to that of a CEO for the project.
- The project manager in a weak matrix typically reports to a higher-level manager, while in a strong matrix, they have more autonomy and report progress directly to the stakeholders.
- Resource availability and project budget are usually controlled by functional managers in a weak matrix but are more likely to be controlled by the project manager in a strong matrix.
