Some team members may be quite passionate about process. In their effort to be pure, do things “the right way,” or simply comply with what they see as “hard rules,” team members can focus too much on process details in place of delivering high-quality value to customers. Those team members may think that following rules and practices precisely is necessary to deliver high-quality value to customers. Following the rules and guidelines in this book is important to a team just starting with Kanban. However, over time your team will internalize visualizing its work and limiting work in progress. Team members will naturally swarm to blocked steps and avoid working on too much at once. At that point, being flexible is an important part of being efficient. You don’t want to compromise on quality, but you should trust your team to operate in the manner that best suits its makeup and current needs. If you find that quality or efficiency has dropped significantly, you can always return to a stricter approach.
