In which scenario would you use design-based specifications?

Design-based specifications are primarily used when there is a need to describe how a product should be constructed or developed. This approach focuses on the technical aspects and processes involved in creating the product, detailing the specific methods, materials, and standards that should be followed during its construction.

In scenarios where the intricacies of the design and methodology are critical to achieving the desired outcome, such as in complex technical systems or specialized projects, design-based specifications provide a clear framework. This ensures that all involved parties have a comprehensive understanding of the construction process, leading to consistent implementation and successful project delivery.

While outlining expectations for service functionality, reviewing vendor capabilities, and assessing market conditions are important components of project management and procurement, they do not specifically address the "how" of product construction, which is the primary objective of design-based specifications.
