This is a great article describing some of the ways in which intelligent automation is a perfect partner for Lean Six Sigma projects and transformation. In summary:
IA is a perfect tool for both large scale transformation initiatives where it can be used to achieve quick wins and speed up the pace of change, and on smaller scale, targeted improvement initiatives where automation is the primary focus
The 80/20 rule – On larger process improvement initiatives, where certain major IT changes are required, IPA can be used to achieve 80% of the benefits of the major IT changes, however the execution time and effort is dramatically reduced.
On smaller scale projects combining Lean methodologies with IPA as the primary improvement tool creates a powerful project approach that can consistently identify achievable, valuable improvements.
