Final answer:
Determining appropriate acquisition ancillaries is not included in the systems selection tasks, which focus on software design, hardware requirements, miscellaneous environmental needs, and the science behind the solution.
Step-by-step explanation:
The systems selection tasks do not include determining appropriate acquisition ancillaries. In the context of systems design and development, the focus is typically on determining the computer software design that implements the logical specifications and selecting the required hardware that satisfies the physical requirements. Determining miscellaneous environmental needs could be a part of the overall consideration but would not typically include acquisition ancillaries. The evaluation of potential designs involves a structured process where requirements must be met, and the best solution is chosen based on the stipulated requirements and constraints.
When developing a detailed design, the chosen solution, such as a solar still for desalination, is elaborated upon by identifying the design architecture, shapes and dimensions, materials and fabrication processes, and the necessary components from external vendors or internal fabrication. The development steps include understanding the physical components, electrical subsystems, and any embedded software. The focus is on designing a system, component, or process that meets desired needs within realistic constraints such as economic, environmental, social, political, ethical, health and safety, manufacturability, and sustainability.
The science connection is important as it requires the documentation of each step, justifying the decisions based on the science behind the chosen solution, and taking into account factors such as requirements and constraints.
