The fourth step is to encourage your team to collaborate and innovate. You don't want to limit or stifle your team's creativity, as this can lead to stagnation, complacency, or mediocrity. You also don't want to discourage or penalize your team's experimentation, as this can lead to fear, risk-aversion, or conformity. You need to create a safe and supportive environment for your team to share their ideas, opinions, and feedback, to learn from their mistakes and failures, and to try new things and solutions. You also need to facilitate and promote your team's collaboration and innovation, by providing them with the necessary resources, tools, and time, by involving them in the decision-making process, and by celebrating their successes and learnings. You can use various techniques to encourage your team to collaborate and innovate, such as brainstorming sessions, hackathons, design sprints, or prototyping. The goal is to unleash your team's potential and passion, and to foster a culture of curiosity and excellence.
