Peter Drucker, a renowned management consultant, educator, and author, emphasized the importance of achieving multiple goals for organizational success. Here's how managers can do this:

1. Deliberately: Managers must be intentional and strategic in setting and pursuing goals. This means they need to understand the organization's mission, vision, and strategic objectives, and align their goals with these. They also need to communicate these goals clearly to their team, and ensure everyone understands their role in achieving them.

2. Simultaneously: Managers should not focus on one goal at the expense of others. Instead, they should strive to achieve multiple goals at the same time. This requires good multitasking and prioritization skills, as well as the ability to balance competing demands and resources.

3. Through negotiation: Achieving goals often involves negotiation, whether it's negotiating resources, timelines, or roles and responsibilities. Managers need to be skilled negotiators, able to advocate for their team and their goals, while also being willing to compromise and find win-win solutions.

4. In a specific order: While managers should strive to achieve multiple goals simultaneously, they also need to understand that some goals need to be achieved before others. This requires them to prioritize their goals and develop a plan or roadmap for achieving them in the most effective and efficient order.
