Problem Solving and Continuous Improvement
View all resources for this topic
Lean techniques can be used to solve problems that happen on site, such as damaged materials, late deliveries, and not meeting schedule deadlines by investigating the root causes and involving everyone relevant and then putting fixes in place. A Lean approach to problem solving normally involves the use of a specific method to get to the root cause of any particular issue.
This includes specific, proven techniques such as the “5 Whys” or developing a herringbone diagram (see the resource library to find out more) to understand all of the different factors which have contributed to any particular issue; the theory being that once you have broken a problem down into smaller chunks it becomes easier to solve.
Another fundamental concept in Lean problem solving is that problems to not arise as a result of individual mistakes by people but instead are caused by a failure of the system itself. Lean Problem solving then allows you to understand what the problems within the system are so they can be fixed.
