For those of you who have been part of an IT operating model redesign, what were the triggering factors that prompted you to do so? What was the most significant change you made?

Triggers also can be in support of transforming people experiences (example - customers, employees, partners experience).

Triggers are usually from Digital Transformation Initiatives, Efficiency and Cost Reduction, Mergers and Acquisitions, Business Growth and Scaling or due to Technology Obsolescence.
