Final answer:
In the project planning phase, planners develop a broad project description and scope. Then, they move to develop a detailed design that includes architecture, material selection, and component identification for prototype creation.
Step-by-step explanation:
In the project planning phase, project planners develop a broad description of what the project is and what its scope will be. This includes defining the problem, which involves understanding the needs of potential customers, identifying competitors, government regulations, technological limitations, and project constraints like personnel, time, and budget. A clear understanding of the project scope and available resources shapes the problem statement, which guides the following steps.
The next step involves developing a detailed design from the general design concept selected. This is crucial as it has a significant impact on project success; a poorly executed detailed design can undermine an excellent concept. The detailed design phase includes establishing design architecture, selecting materials and processes, and identifying components in enough detail that prototypes can be created.
