Diseño de una solución integral de control y trazabilidad de inventarios mediante lean manufactoring y herramientas tecnológicas en la Empresa SICET S.A.

Abstract

The management of tool and equipment inventory is a critical factor for engineering services companies, given its direct impact on operational efficiency, costs, and organizational sustainability. This paper presents a case study applied to SICET S.A.S., a company based in Bogotá D.C. that faces quantifiable losses in its inventory: six tools lost or under claim with a total value of $2,940,000 COP, an average tool search time of 399 seconds per cycle with peaks of up to 803 seconds, and a return process with no formal record or digital backup. To address this problem, a mixed-methods case study was conducted under the Lean Six Sigma methodology and the DMAIC cycle. Data collection was carried out through a formal time study of 45 observed cycles, an interview with the warehouse supervisor, and a review of the physical tool delivery records. Quantitative analysis (descriptive statistics and a Pareto diagram) shows that three activities concentrate 87% of the total operational time: searching for tools (48%), receiving requests (69% cumulative), and relocating tools (87% cumulative). Based on these findings, an integrated solution was designed combining the physical reorganization of the warehouse using an As Is - To Be model with zone classification by item type and rotation, ABC classification and the FIFO method for inventory control, and the design of an HTML web application to digitally record tool delivery, transfer, and return with individual responsibility assignment per worker. The project scope covers the design of the solution; full implementation of the web system is a subsequent phase. The results provide a quantitative baseline of the process and a structured proposal to reduce losses, strengthen internal control, and improve operational efficiency at SICET S.A.S.
