Final answer:
The first step in selecting technologies to meet a set goal is to define your goals and objectives with specificity using the 5 W's. Following that, conduct thorough research on existing solutions and gather information to make an informed decision. Finally, evaluate potential designs with a structured process that aligns with the requirements and constraints.
Step-by-step explanation:
The first step when selecting technologies to meet a set goal is to define your goals and objectives. This involves considering the 5 W's to help make your goal specific: Who is involved, What do you want to accomplish, Where will it take place, When does it need to be completed by, and Why is it important to do so. Once the goal is clearly defined, it is essential to gather information and research existing solutions. Identify what others have done to address a similar need and determine whether to build upon their work or take a different path. Finally, you must evaluate solutions where potential designs are assessed against constraints and criteria. The selection is made using a structured process that ensures requirements are met and selects the best design according to those requirements and constraints. The science connection is crucial, as all steps of the design process should be documented, and the science behind the choice should be clearly justified.
This initial planning phase is critical because it shapes the direction of the project and ensures that the selection of technology is aligned with the specific needs and goals. For instance, if the chosen design was a solar still for desalination, subsequent design steps would consider the efficiency, cost-effectiveness, and environmental impact of that technology.
