An "Overture" in the context of a proposal refers to an initial approach or introduction to a project or idea. It serves as a way to present the main concepts and objectives, often aiming to capture the interest of potential stakeholders or decision-makers. This preliminary communication sets the stage for further discussions and detailed planning. In various fields, such as business, theater, or music, an overture can take different forms. In business, it might be a formal document outlining a project’s goals, while in theater, it could refer to a musical introduction that hints at the themes of the performance.
