Embarking on a managerial role comes with its unique set of challenges and responsibilities. For new managers, particularly those eager to instill a lean culture within their teams, the first 90 days are crucial.

Developing a lean culture is not just about cutting costs; it’s a mindset that emphasizes efficiency, continuous improvement, and employee engagement. Here’s a comprehensive guide to help new managers support a lean culture during their initial 90 days.

1. Understand the Principles of Lean: Before you can foster a lean culture, it’s crucial to have a deep understanding of lean principles. Familiarize yourself with concepts such as value stream mapping, waste reduction, and continuous improvement. Consider undergoing lean training or seeking mentorship from experienced leaders in your organization.

2. Build Relationships and Establish Trust: The foundation of a successful lean culture is built on trust. Take the time to connect with your team members individually. Understand their strengths, challenges, and aspirations. Open communication channels and demonstrate a genuine interest in their well-being.

I suggest spending 80%-90% of your first 90 days at the gemba (place where the work is being done). In fact, I would schedule a rotation of working in each area to learn the process, build relationships, and look for opportunities.

3. Conduct a Current State Assessment: Assess the existing processes and workflows within your team or department. Identify bottlenecks, redundancies, and areas of potential improvement.

I suggest sitting down with every one of your direct reports 1-on-1 and asking the same three questions:

1. What is going well/good in your department/area?
2. What is not going well/good in your department/area?
3. What ideas do you have for improvement in your deportment/area?

These conversations and this assessment will not only communicate a strong message to your team, they will serve as the baseline for your lean initiatives.

4. Follow the System: Do not try to change anything in your first 90 days! Rather, learn the current management system and support it. If the organization has a solid lean management system in place, it is your job as a leader to ensure stability by falling in line and promoting the system as the way you manage. That doesn’t mean you cannot have your own “leadership style,” but far too often, organizations create a level of instability in their operations by intentionally introducing new leaders and encouraging them to “change things up.” You cannot improve in an environment filled with chaos.

If, after 90 days, you find the organization does not have a solid management system in place, begin by setting clear expectations. Clearly communicate your expectations regarding a lean culture. Emphasize the importance of efficiency, collaboration, and continuous improvement. Ensure that your team understands the value of their contributions to the overall success of the organization.

Implement key performance indicators (KPIs) to track the progress of your lean initiatives. Regularly review these metrics and adjust your strategies accordingly. Flexibility and adaptability are key components of sustaining a lean culture.

In the first 90 days as a new manager, your actions will set the tone for the culture within your team. By prioritizing understanding, collaboration, and continuous improvement, you can lay the groundwork for a lean culture that not only drives efficiency but also fosters a positive and engaging work environment. Through ongoing commitment and a focus on the principles of lean, you can lead your team towards sustained success and innovation.
