Improvement Specialists are responsible for leading the deployment of improvement strategy, for training others and for providing broad and deep technical expertise in advanced and complex Lean and Six Sigma, Project and Change Management principles and tools to enable identification and delivery of improvement opportunities aligned to key business goals.

Improvement Specialists typically report to Improvement Leaders who develop the improvement strategy and governance processes, and who provide technical guidance on advanced analysis. Improvement Specialists manage (directly and/or matrix) Improvement Practitioners who lead smaller improvement projects aligned to the improvement strategy. A typical ratio of Improvement Specialists to Improvement Practitioners in an organisation could be 1:10. In comparison with the work of an Improvement Practitioner, Improvement Specialists draw on their advanced knowledge and skills in applying Improvement principles and tools across a range of programmes/ projects/areas to build the capability of others.  They also swiftly visualise processes, problems and opportunities and use both graphical and statistical analysis to deliver improvements.

They work closely with other Improvement Specialists to support the delivery of improvement strategy, working on multiple simultaneous projects linked to key business objectives, identifying and engaging both subject matter experts and key stakeholders. Their work generally requires them to interact with others but typically involves a high-degree of autonomy.
