| The '''Constructive Systems Engineering Cost Model (COSYSMO)''' was created by Ricardo Valerdi while at the [[University of Southern California]] Center for Software Engineering. 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]], [[Science Applications International Corporation|SAIC]], [[General Dynamics]], and [[BAE Systems]].

| 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.
| |
| | |
| COSYSMO's central cost estimating relationship, or CER is of the form:
| |
| <math>PM_{NS}=A \times Size^E \times \prod^n_{i=1} EM_i</math> | |
| | |
| where "Size" is one of four size additive size drivers, and EM represents one of fourteen multiplicative effort multipliers.
