Which of the following is NOT a step the owner should take before soliciting applications for design services?

The correct answer is the development of a marketing campaign, as it is not directly related to the essential preparatory steps an owner should take before soliciting applications for design services.

Preparing a complete scope of work is crucial because it outlines the expectations, deliverables, and project objectives, allowing prospective design service providers to understand the project requirements. Identifying the basis of compensation is important as it establishes how the design services will be compensated, whether through fixed fees, hourly rates, or other means, which is necessary for transparent negotiations and budget planning. Establishing standard contract terms is also essential, as it sets the framework for the engagement and protects both the owner and the design professional by clarifying rights and responsibilities.

In contrast, developing a marketing campaign is not a prerequisite for soliciting design services. It pertains more to attracting potential clients or promoting a project rather than defining the project scope, compensation, or contractual terms necessary for starting the selection process for design services. Therefore, it stands out as unnecessary in this context.
