The term "big picture" refers to a comprehensive view or understanding of something, by considering all relevant factors and aspects. It is an expression that encourages people to step back from small details and focus on the overall context, goals, and objectives. In other words, it means looking at the situation in its entirety, rather than getting bogged down with minor issues or specifics. The phrase can be used in various situations such as business planning, project management, decision-making, etc., to help people see the broader perspective and make better choices based on a clear understanding of the bigger picture.
