The Constructive Systems Engineering Cost Model (COSYSMO) was created by Ricardo Valerdi while at the University of Southern California Center for Software Engineering [1], . It gives an estimate of the number of person-months it will take to staff systems engineering resources on hardware and software projects. Initially developed in 2002, the model now contains a calibration data set of more than 50 projects provided by major aerospace and defense companies such as Raytheon, Northrop Grumman, Lockheed Martin, SAIC, General Dynamics, and BAE Systems. The University of Southern California (also known as USC, SC, Southern California and Southern Cal), located in the urban center of Los Angeles, California, was founded in 1880, making it Californias oldest private research university. ... Raytheon Company NYSE: RTN is a major United States military contractor based in Waltham, Massachusetts. ... The Northrop Grumman Corporation (NYSE: NOC) is an aerospace and defense conglomerate that is the result of a 1994 merger between Northrop and Grumman. ... Lockheed/BAE/Northrop F-35 Lockheed Trident missile C-130 Hercules; in production since the 1950s, now as the C-130J Lockheed Martin (NYSE: LMT) is an aerospace manufacturer formed in 1995 by the merger of Lockheed Corporation with Martin Marietta. ... This is a disambiguation page — a navigational aid which lists other pages that might otherwise share the same title. ... General Dynamics NYSE: GD is a defense conglomerate formed by mergers and divestitures, and as of 2005 it is the sixth largest defense contractor in the world [2]. The company has changed markedly in the post-Cold War era of defense consolidation. ... Systems plc is the worlds fourth largest defence contractor and a commercial aerospace products manufacturer. ...

Similar to its predecessor COCOMO, COSYSMO computes effort (and cost) as a function of system functional size and adjusts it based on a number of environmental factors related to systems engineering. COCOMO is a model designed by Barry Boehm to give an estimate of the number of man-months it will take to develop a software product. ...
