Systematization of Scientific Research on Integrated Management Systems in SMEs: Trends, Benefits, and Limitations (2019–2025)

Resumen

The adoption of Integrated Management Systems (IMS) has emerged as a strategic approach for enhancing organizational performance in small and medium-sized enterprises (SMEs). Nevertheless, scientific evidence regarding their implementation within the Latin American context remains fragmented and inconsistent. Accordingly, this study aimed to systematize and critically analyze the scientific literature on IMS implementation in SMEs published between 2019 and 2025, identifying prevailing research trends, reported benefits, and key limitations associated with the integration of ISO 9001, ISO 14001, and ISO 45001 standards. A descriptive–analytical approach was employed through a systematic literature review conducted in accordance with PRISMA 2020 guidelines. From an initial pool of 412 records, a final sample of 20 studies met the established inclusion criteria. The findings reveal that ISO 9001 continues to be the most widely adopted standard among SMEs, whereas the integration of environmental and occupational health and safety standards exhibits a gradual upward trend. The most frequently reported benefits include enhanced operational efficiency, increased competitiveness, and improved business sustainability. Conversely, high implementation costs, limited technical expertise, and persistent informality are identified as the most significant barriers to effective IMS integration. In conclusion, Integrated Management Systems represent a valuable strategic tool for strengthening SMEs; however, their effective implementation in Latin America requires the development of flexible, context-specific integration methodologies aligned with the structural constraints faced by these organizations.
