Final answer:
In a weak matrix organization, the project manager seeks part-time resources from functional departments due to shared authority and resource allocation.
Step-by-step explanation:
During project build-up, if a weak matrix organizational form is used, the project manager seeks a commitment of part-time resources from the functional departments. In a weak matrix organization, the authority of the project manager is limited, and personnel usually report to their respective functional managers.
Therefore, resources are often shared across projects, necessitating the need for part-time commitments from various functional areas. As full-time dedicated resources are typically unavailable, project managers must coordinate schedules and negotiate for the necessary staff time to support project tasks.
In a weak matrix organizational structure, the project manager does not have direct authority over the resources, so they rely on part-time resources from the functional departments to work on the project. This means that the resources will be working on the project while still fulfilling their regular duties in their respective departments.
Therefore, the correct answer is b) Part-time resources.
