Final answer:
The best method of procurement for a complex project is one that allows for a structured evaluation of potential solutions against set criteria, like the example of choosing a solar still for desalination, ensuring the selected option offers the best value for money within societal structures.
Step-by-step explanation:
The method of procurement best placed to deliver value for money on a complex project involves evaluating multiple solutions against set constraints and criteria in order to select the one that best fits the project's requirements. This structured selection process is crucial, especially in the context of complex engineering problems that often require careful consideration of numerous factors such as cost, sustainability, and efficiency. To ensure the best outcome, the chosen procurement method should facilitate thorough evaluation and comparison of potential designs, like the example of selecting a solar still for desalination, which then allows for further detailed design and prototyping. Large-scale projects historically, whether it's constructing pyramids or modern infrastructure, involve considerable resources and organization, highlighting the need for an effective procurement strategy that integrates well within the broader societal structures.
