Integrated framework for productivity improvement: Action research approach with lean construction theory

Lean construction theory is universally being applied in many actual projects for productivity improvement and process innovation. Most of proposed lean approaches, however, could not guide an actual implementation to the level of expected improvement, largely due to their inapplicability under in-situ circumstances. To reduce the gap between the theoretical approach and practical application, this paper suggests an action research approach integrated with lean construction theory to provide more practical solutions in a real setting. The results of a pilot case study showed that productivity was almost doubled than before applying proposed approach. Effectiveness of this framework will be further validated through applying to more broad case applications.
