    • Collected Views on Complexity in Systems 

      Sussman, Joseph M. (Massachusetts Institute of Technology. Engineering Systems Division, 2002-05)
      The term complexity is used in many different ways in the systems domain. The different uses of this term may depend upon the kind of system being characterized, or perhaps the disciplinary perspective being brought to ...
    • Combating System-Level Quality Problems in Complex Product Development 

      Whitney, Daniel E. (Massachusetts Institute of Technology. Engineering Systems Division, 2007-02)
      As products become more complex and their development involves more technologies, people, and companies, it is no longer sufficient to ensure that each part, component, or subsystem is designed and made correctly. Problems ...
