AB  - The construction industry is increasingly adopting Modern Methods of Construction (MMC) to improve productivity, predictability, and integration across project stages. While Lean Construction is widely recognized as a key enabler of MMC, existing research has primarily examined Lean practices in isolation or emphasized short-term planning routines, offering limited insight into how these practices are articulated across planning horizons and governed in practice. This study investigates how Lean practices are distributed and articulated across planning horizons in MMC-based production systems, and how digital support shapes the governance of planning and control across off-site and on-site operations.
The study integrates empirical evidence from multiple Brazilian construction projects to identify cross-cutting patterns. It finds Lean practices are more mature at the operational level but remain weak at strategic and tactical layers—especially in medium-term planning and off-site logistics. Digital tools improve transparency and coordination, yet they alone do not ensure effective articulation across planning horizons.
The paper contributes to Lean Construction theory by showing that, in MMC-based production systems, the Last Planner System (LPS) can be interpreted not only as a planning and control system, but also as a governance-oriented mechanism for aligning decisions, commitments, and information across planning horizons.
