Final answer:
The two dimensions within the actual execution of projects are time and cost. Balancing these dimensions is crucial for successful project execution.
Step-by-step explanation:
The two dimensions within the actual execution of projects are time and cost. Time refers to the scheduling and timeline of project activities, while cost refers to the budget and financial resources required for the project.
For example, in a construction project, the time dimension involves setting the start and end dates for different construction phases, while the cost dimension involves estimating the cost of materials, labor, and equipment. Balancing these dimensions is crucial for successful project execution.
