Resumen

Improving delivery reliability has become a major challenge for the construction sector. In Peru, more than 60% of SME construction projects experience schedule deviations, largely due to inefficient procurement processes and frequent rework. This study addresses the low Duration Performance Index (DPI) observed in a Peruvian SME construction company by implementing a Lean Service based improvement approach. The methodology integrates BPMN and SIPOC to map and standardize procurement and execution workflows, 5S and ABC classification to organize and prioritize critical inventory items, and a Kanban system supported by PDCA cycles to control task progression and reduce rework. A pilot intervention was first applied to validate the effectiveness of the proposed tools, followed by a discrete-event simulation using Arena to evaluate the TO-BE scenario under comparable operating conditions. Results indicate that BPMN and SIPOC reduced delays associated with reactive procurement by improving the planning and issuance of purchase orders; 5S and ABC eliminated stockout-related interruptions by ensuring the availability of critical materials; and Kanban stabilized task execution, significantly reducing rework. These findings highlight the potential for replicating the proposed Lean framework across other SMEs in the construction sector.
