A Lean-Integrated Conceptual Framework for Value Optimisation of Construction Project Briefing by Enhancing the Client Needlessness

The construction industry continues to face significant challenges in project value optimisation in the early briefing stage, which leads to rework, cost overruns, and value loss. This study aims to address the neglect of cilent’s “needlessness” in the value definition process during the early briefing stages and establish a structured framework to optimise project value from the outset. A deductive methodology is adopted, by integrating Value Management, SMART method, Lean Construction, and behavioral decision-making via a systematic literature review (SLR) and conceptual modeling. The framework is theoretically validated through logical consistency testing and expert review. Key findings reveal that formalising “needlessness” identification can effectively reduce briefing stage waste compared to conventional VM practices. The proposed framework enhances the SMART VM methodology by explicitly incorporating “needlessness” identification to form a protected “Value Boundary” and introducing a quantitative feedback mechanism to objectively close iterative briefing cycles. This framework advances VM theory by formalising “needlessness” as a core component, extends LC application to early project phases, and provides a practical tool to align stakeholders, reduce waste, and guarantee project value.
