Seagull model is a kind of theoretical tool widely used in management and decision making. With its unique structure and function, it helps organizations to make more rational and effective decisions in complex environment. The core idea of the model is to integrate information and resources through different levels of analysis, so as to optimize the decision-making process.

The model is usually divided into several levels, starting with the strategic level. This level focuses on the organization's long-term goals and overall direction, involving key issues such as resource allocation, market positioning, and risk management. At this stage, decision-makers need to conduct an in-depth analysis of the external environment, identify potential opportunities and threats, and develop a clear strategic plan.

Then there is the tactical level. This phase focuses on implementing the established strategy, developing specific action plans, and ensuring that the various departments and teams can collaborate effectively. Decision makers need to consider how to maximize efficiency with limited resources, often involving the use of tools such as project management and process optimization.

Finally, there is the operational level. At this level, organizations need to focus on the details of day-to-day operations and execution. Decisions at this stage often involve specific matters such as staffing, resource use and time management to ensure the implementation of strategies and tactics.

A big advantage of the Seagull model is its systematicness and flexibility. By conducting comprehensive analysis at different levels, it can help decision makers avoid decision-making errors caused by one-sided consideration of problems. At the same time, the flexibility of the model allows it to be adapted to organizations of all sizes and types, whether it is applied in enterprise, government or non-profit institutions.
