Deployment Of A Lean Six Sigma Continuous Improvement Culture

Deployment of a Lean Six Sigma Continuous Improvement Culture

Our client, Anglian Water Services (AWS), covers the largest geographical area in England and Wales, employing 5,000 people and supplying water and water recycling services to more than six million customers in the east of England and Hartlepool.

Business Challenge

ChangeWise were appointed directly by AWS in 2016 to support them in deploying a Lean Six Sigma continuous improvement culture across the organisation to improve efficiency, effectiveness and customer service. ChangeWise designed several Lean Sigma and Operational Excellence training courses, accredited by the Lean Competency System (LCS), called ‘Love Every Minute’, aiming to ‘Get it right first time, every time’.

Courses were delivered to more than 25% of employees, Alliance Partners and other strategic collaborators. Over a four year period, candidates attended tailored courses, sat online tests and applied learning to workplace practices to complete a project delivering tangible benefits in their own business areas. Employees were mentored throughout the process by ChangeWise, and assessed and scored on their submissions to gain industry-wide recognised qualifications.
