Planning is a crucial aspect of organizing a sports tournament as it helps in ensuring the smooth execution of the event. There are several important objectives of planning in a sports tournament, which are listed below:

1. Timely achievement of target:
- The primary objective of planning in a sports tournament is to set clear targets and goals.
- These targets can include the number of participants, revenue generation, audience attendance, or any other specific objectives.
- Planning helps in breaking down these targets into smaller milestones, allowing for a step-by-step approach towards achieving them.
- By setting realistic timelines and monitoring progress, planning ensures the timely achievement of these targets.

2. Coordination:
- Another important objective of planning in a sports tournament is to ensure coordination among various stakeholders.
- This includes teams, players, coaches, officials, volunteers, sponsors, media, and spectators.
- Effective planning helps in establishing clear lines of communication, assigning responsibilities, and coordinating activities to ensure the smooth functioning of the tournament.
- It ensures that all stakeholders are on the same page and working towards a common goal.

3. Improving sports performance:
- Planning also plays a significant role in enhancing the sports performance of the participants.
- It includes developing training schedules, designing practice sessions, and implementing strategies to improve skills, tactics, and overall performance.
- Planning helps in identifying strengths and weaknesses, setting performance targets, and providing necessary resources for training and development.
- By focusing on the improvement of sports performance, planning contributes to the overall success of the tournament.

4. Financial sustainability:
- While planning is essential for financial sustainability, it is not the objective to solely earn money.
- The objective is to ensure that the tournament's financial aspects are well-organized and managed.
- This includes budgeting, acquiring sponsors, ticket sales, merchandising, and other revenue-generating activities.
- The aim is to cover the costs of organizing the tournament, provide adequate facilities and resources, and create a sustainable platform for future events.
- However, the primary focus should be on the quality of the tournament and the experience provided to participants and spectators rather than solely earning money.

In conclusion, planning in a sports tournament aims to achieve timely targets, ensure coordination, and improve sports performance. While financial sustainability is a crucial aspect, the objective is not to solely earn money, but rather to create a well-organized and successful event.
