This work proposes a method to estimate the probability of meeting functional requirements of complex products. The method uses concepts and techniques from Systems Engineering and from Reliability. Functional interactions represented in the Functional Flow Block Diagrams (FFBD) are translated into a correspondent configuration of the reliability block diagram (RBD), according to the method's conventions. After that, a reliability value is attributed to each component block, and using reliability evaluation methods the probability of meeting a particular functional requirement is estimated. An application example is presented by missile's subsystem.
