I believe there are three keys to strong leadership and management:
First, you have to have a clear and ambitious vision for the future your team is creating and communicate it so that they believe it. Next, you need to look after the individual team members and promote psychological safety. Finally, you need to break your vision down into clear goals and let each team member know what they are responsible for, then let them get on with it.
Vision: the ability to think about or plan the future with imagination or wisdom.Oxford Languages
Wellbeing: the state of being comfortable, healthy, or happy.Oxford Languages
Productivity: the effectiveness of productive effort, especially in industry, as measured in terms of the rate of output per unit of input.Oxford Languages
A new manager can start with simple steps for each of the three elements and then gradually built upon them to spiral out their capabilities as a manager and leader. For example, once you have written a vision, you are holding regular open and honest 1:1 meetings with each team member, and everyone is clear on what they should be working on, you could turn your vision into a strategy, You could add a daily stand each morning to build community in the team, and you can start to have more control over the flow of work by identifying and removing constraints.
If you want some ideas on how to spiral out your vision and productivity, Jim Collins’s Level 5 leadership and the Capability Maturity Model (CMM) are an excellent place to start. For wellbeing, begin by learning about creating a psychologically safe workplace and then take the lessons of Self-determination theory to encourage your team to develop autonomy, competence, and relatedness in their work.
