Generally spoken there are multiple kinds of analysis that can be made during the first phase of the UX workflow before the other phases are started.

The key elements that need to be considered are the users with their needs and pain points for example.

Other external factors like a corporate design or the corporate identity must be taken into consideration. These are external factors that come from other stakeholders who are involved in the project.
