This post presents our final proof-of-concept test of our prototype professional development Ladder of Opportunities in Workplace Innovation in the work domain of Accountancy. These tests were intended to identify how well the framework fits with what we know about workplace innovation in a specific workplace domain and to identify some of the context-specific issues to be addressed for the framework to be used productively. Previous posts looked at Job Crafting, Innovation Adaptation (including specific examples from the Audit area) and Design Innovation (with a focus on Design Thinking in Accountancy).
