Manufactura Justo a Tiempo - Enfoque Práctico presents a practical Spanish-language introduction to just-in-time production systems for manufacturing environments. The work explains how organizations can align purchasing, scheduling, and shop-floor operations to reduce excess inventory, shorten lead times, and respond more closely to demand. Aimed at managers, engineers, and students, it frames just-in-time methods as a disciplined approach to workflow control rather than a purely theoretical model. The emphasis is on implementation: identifying bottlenecks, coordinating suppliers, improving production flow, and building routines that support continuous improvement. As a business and operations-management text, it is useful for readers seeking a grounded overview of lean-oriented manufacturing practices in Spanish.
