Which action is NOT recommended for effective management of subcontractors?

Withholding information until the project is done is not a recommended action for effective management of subcontractors. Effective management hinges on open communication and transparency. Providing subcontractors with timely and relevant information ensures they understand the project scope, their responsibilities, and how their work impacts the overall project.

When information is withheld, it can lead to confusion, mistakes, and delays, as subcontractors may not be able to plan their work effectively or respond to any changes in a timely manner. Consequently, fostering an environment of collaboration and transparency enhances trust and accountability, which are critical for successful project execution.

In contrast, actions like providing feedback and support, defining roles and expectations, and conducting regular check-ins and updates are essential practices that help to ensure subcontractors are aligned with project goals and can perform at their best.
