Final answer:
The two dimensions within project execution are technical, focusing on project deliverables and specifications, and social, focusing on people management and team dynamics.
Step-by-step explanation:
The two dimensions within the actual execution of projects are technical and social. The technical dimension involves the application of knowledge and practices to create the deliverables of the project and ensure that all specifications and requirements are met.
On the other hand, the social dimension focuses on the people involved in the project, including team dynamics, leadership, communication, and stakeholder management. Good project execution requires a balance and integration between these two dimensions to achieve the project's objectives.
