When you consider the expected costs of a solution, you focus on the negative value a new solution may introduce to the organization.

A negative value can be described in different ways, including the cost to acquire the solution or any negative effects it might have on stakeholders. It can also include the cost to maintain the solution over time. 

Some types of expected costs that should be considered when analyzing the potential value of each design option can include the timeline, the effort, operating costs, purchase and/or implementation costs, maintenance costs, physical resources, information resources, and human resources.
