BRIDGING PROBLEM AND SOLUTION SPACES: DEVELOPING AN INNOVATION FRAMEWORK WITH LEAN AND AGILE METHODS IN CONSTRUCTION

Abstract

This research addresses the challenges of innovation and productivity in the construction industry by leveraging the Problem-Space Framework (PSF) and the Solution-Space Framework (SSF). The Problem-Space Framework (PSF) identifies and prioritizes organizational pain points, while the Solution-Space Framework (SSF) focuses on iterative solution development. These frameworks integrate Lean Construction and Agile methodologies to identify, prioritize, and address organizational pain points systematically. A previous paper Etges ten Caten (2023) had already developed the understanding of the PSF and the pain-point identification. Initially, the PSF focused on diagnosing and defining challenges through workshops, data collection, and prioritization, providing companies with a structured approach to innovation. Subsequent refinements incorporated Lean Construction maturity assessments, improved prioritization tools, and greater involvement of site teams, enhancing the PSF's effectiveness. The second phase of the study introduced the SSF, which emphasizes solution development through iterative cycles. This research aims to develop and validate an innovation framework that integrates the PSF and SSF with Lean and Agile methods to improve innovation and productivity in the construction industry. Agile methodologies structured the process, ensuring adaptability and collaboration. The phased implementation of pilots enabled incremental testing and refinement of solutions. In the third phase, the Innovation Framework was applied in Company R, incorporating lessons learned from Company M and further aligning the framework with industry needs. Tailored workshops and Lean maturity assessments enhanced its adaptability and impact. The framework results highlight the potential of integrating Lean and Agile practices to foster systematic innovation in construction, bridging the gap between identifying challenges and implementing effective solutions. The quantified results are under evaluation as it is ongoing research.
