What is generated by proprietary software in the Prepare stage?

In the Prepare stage of a project, proprietary software typically plays a crucial role in generating specific documents that are essential for the project’s development and execution. The generation of lease agreements fits this context perfectly, as these documents are foundational legal instruments that outline the terms and conditions upon which a property or a service is leased. This stage often involves the creation and management of such agreements to ensure that all parties are aligned and that contractual obligations are clearly defined.

The other options, while vital components of project management and execution, do not specifically relate to what proprietary software generates during this particular stage. Project timelines are usually developed based on planning discussions, stakeholder feedback pertains to responses and insights from participants, and team assignments are typically determined through organizational processes rather than generated by the software itself. Therefore, lease agreements stand out as the correct answer since they are a direct product of the software's capabilities in managing legal documentation.
