In engineering contexts, one often does not actually implement a design, but rather uses an existing implementation. The process of getting an existing solution to work might require some time and effort, and I'm looking for the verb describing this effort.1
You haven't implemented anything yourself, and you're not integrating anything yet either, but this still may take up a lot of time. So, how do you describe what you're doing?
