Assessing Lean Construction Maturity

Embedding Lean Construction (LC) in an organisation typically requires many changes and is a challenging endeavour. In particular when transformations take place it becomes crucial to measure the current state of the maturation process. Hence there is a requirement for organisations to be able to demonstrate where they are in their LC journey. It has been widely acknowledged that maturity models (MM) provide organisations with such an assessment of the current state. Further benefits of MMs are the guidance and support when implementing a change or improvement strategy. The research presented aims to integrate both LC and MM to enable organisations to measure their current maturity in LC. A qualitative mixed method design was used including focus groups and interviews to explore the phenomenon of LC maturity from key informants. The major findings of the research are: MM can be integrated with LC, and a proposed validated framework can assess the current state of LC maturity within an organisation. The proposed LC maturity assessment framework labelled (LCMM) comprises five maturity levels, 11 Key Attributes, and 60 defined Behaviours, Goals & Practices with 75 Ideal Statements to measure the maturity within organisations embedding LC. This framework provides important support and guidance in the organisational LC maturation process
