A "Ball Park" estimation refers to a rough calculation or approximation of a value, often used when precise data is unavailable. This method provides a general idea of costs, time, or quantities, helping individuals and businesses make informed decisions without needing exact figures. In various fields, such as business, engineering, and project management, ball park estimates are useful for initial planning stages. They allow stakeholders to gauge feasibility and allocate resources effectively, even if the final numbers may differ significantly from the initial estimates.
