Accelerating System of Systems Engineering Understanding and Optimization through Lean Enterprise Principles
Lane, Jo Ann; Valerdi, Ricardo (2010-04-05)By applying a lean enterprise lens to studies of the evolving field of system of systems engineering (SoSE), it has been observed that many SoSE teams are developing processes that are consistent with many lean enterprise ... -
Advancing an Ontology for Systems Engineering to Allow Consistent Measurement
Honour, Eric C.; Valerdi, Ricardo (2006-04-07)Past analysis has shown that there is a quantifiable correlation between the amount, types and quality of systems engineering efforts used during a program and the success of the program. For any given program, an amount, ... -
Approaches to Calculating Systems Engineering Schedule in Parametric Cost Models
Gaffney, John E.; Valerdi, Ricardo; Ross, Michael A. (2009-04-20)This paper provides two similar approaches for calculating project schedule from a systems engineering perspective. To illustrate the genesis of each approach, we provide two analogies; one from ... -

Cognitive Limits of Software Cost Estimation
Valerdi, Ricardo (2007-09-20)This paper explores the cognitive limits of estimation in the context of software cost estimation. Two heuristics, representativeness and anchoring, motivate two experiments involving psychology students, engineering ... -
Convergence of Expert Opinion via the Wideband Delphi Method: An Application in Cost Estimation Models
Valerdi, Ricardo (2011)This paper discusses the notion of collective intelligence through the application of the Wideband Delphi method as a way to obtain convergence among a group of experts. The specific application is the definition and ... -

Cost and Risk Considerations for Test and Evaluation of Unmanned and Autonomous Systems of Systems
Deonandan, Indira; Valerdi, Ricardo; Lane, JoAnn; Macias, Filiberto (2010-06-22)IEEE Systems of Systems Engineering Conference presentation -
Cost and Risk Considerations for Test and Evaluation of Unmanned and Autonomous Systems of Systems
Deonandan, Indira; Valerdi, Ricardo; Lane, Jo Ann; Macias, Filiberto (2010-06-22)The evolutionary nature of Unmanned and Autonomous systems of systems (UASoS) acquisition needs to be matched by evolutionary test capabilities yet to be developed. As part of this effort we attempt to understand the cost ... -
Cost Metrics for Unmanned Aerial Vehicles
Valerdi, Ricardo (2005-09-26)This paper aims to enhance the understanding of UAV cost metrics and their uses. The paper is organized into three main areas: (1) overview of current approaches for aircraft, (2) life cycle issues with UAV cost estimation, ... -
COSYSMO & COSYSMO-R Parameter Estimation Biases
Smith, Eric D.; Pineda, Ricardo L.; Aldous, Karla; Valerdi, Ricardo (2010-03-17)8th Annual Conference on Systems Engineering Research (CSER) presentation -
COSYSMO: A Systems Engineering Cost Model
Valerdi, Ricardo; Boehm, Barry W. (Génie logiciel, 2010-03)Building on the synergy between systems engineering and software engineering, we have developed a parametric model to estimate systems engineering costs. The goal of this model called COSYSMO (Constructive Systems Engineering ... -
Cultural Barriers to the Adoption of Systems Engineering Research
