Final answer:
The technical dimension of project management involves the formal, disciplined aspects such as planning and scheduling. This dimension ensures an understanding of physical components, shapes, dimensions, and detailed designs, and its documentation is crucial to engineering processes.
Step-by-step explanation:
The question is asking which dimension of the project management process involves formal, disciplined, and purely logical parts such as planning, scheduling, and controlling projects. The correct answer to the question is a) Technical dimension. The technical dimension is fundamental in engineering as it ensures an understanding of all physical components and their shapes and dimensions, discerns components to be sourced or fabricated, and includes detailed designs like schematic diagrams and computer codes for systems and embedded processes. Documentation and justification of the design process are crucial to demonstrate the science behind decision-making within the technical dimension. This scientific and systematic approach is central to addressing criteria and constraints of a project, including economic, environmental, social, and other relevant factors.
