This is the Lean problem solving approach used by leaders and process performers to resolve problems in an organization. The approach begins with steps to clearly identify the problem prior to begining work to resolve it. Information and data relating to the problem is obtained by doing a Go See to observe the problem first hand. This is followed by the analysis to identify the root-cause or root-causes of the problem. Counter-measures are then developed and an implementation plan is put in place. After implementation of the counter-measures other measures involving standardized work and visual management are performed to ensure that performance improvements are sustained over the long term. Leaders, managers, other key individuals and teams require in-role coaching on how to carry out these steps effectively using the A3 Problem Solving approach.
