This text describes and integrated process for designing, developing, operating, and maintaining models and simula-tions to support mission objectives. It emphasizes usingsound principles from systems engineering, describes theprocesses and tools needed to create effective products, andprovides broad insights to help one apply modeling andsimulation creatively.
