[email protected] Engineering changes are an inherent part of the design and development process and can play an important role in driving the overall success of the system. This work seeks Massachusetts Institute of Technology, to create a multidimensional understanding of change activity in large systems that can E40-261, 77 Massachusetts Avenue, help in improving future design and development efforts. This is achieved by a posteriori Cambridge, MA 02139 analysis of design changes. It is proposed that by constructing a temporal, spatial, and fi- nancial view of change activity within and across these dimensions, it becomes possible Rene Keller to gain useful insights regarding the system of study. Engineering change data from the e-mail:
[email protected] design and development of a multiyear, multibillion dollar development project of an off- shore oil and gas production system is used as a case study in this work. It is shown that Bob Robinson the results from such an analysis can be used for identifying better design and manage- e-mail:

The isolation and identification of change hotspots can be helpful Concept Development Engineering, in uncovering potential systemic design issues that may be prevalent. Similarly, strategic BP ICBT, Bldg 200, Chertsey Road, engineering and management decisions can be made if the major cost drivers are known.
