This research work was prepared based on the current situation of a construction company and its poor process of supplying materials to the works, which generated operational cost overruns, reprocessing, among others. Initially, the diagnosis of the initial situation was carried out with the 5 why's tools and carrying out the DAP of the purchasing process, focusing on the planning process and the purchase order issuance process. Based on this, the Ishikawa diagram was created with the main root causes, to determine the main problem facing the company. Once identified, the economic impact was calculated, and the operation times were recorded based on the information provided by the company to prepare the activity diagram of the current process. Subsequently, an improvement proposal was structured based on the Lean Construction philosophy and its tools, the Kaizen method (continuous improvement of the Deming cycle) and adjusting the Just in time purchasing system with the objective of remedying the conditions that create a negative impact on the operating process or, failing that, eliminate said conditions. Finally, after implementing the improvement proposal in the construction company and analyzing the resulting scenario, the viability of the project was demonstrated through indicators, such as the net present value (VAN) (S/. 28,061.43), the internal rate of return (TIR) (44.54%) and the benefit-cost ratio (B/C) (1.90).
