The Engineering Software sub-series consists of reports on topics such as the Geographic Information System (GIS), Engineering Software, and Product Lifecycle Management (PLM) markets and the various segments (such as cPDM, AEC, EDA, CAD, CAM, CAE, CFD, and FEA) that these markets are present in. The reports have been written using a blend of primary and secondary research techniques. Extensive searches were conducted on the Internet, and copious amounts of data were collected from various sources including leading trade publications, trade and industry associations, and business publications. Market data was also derived by conducting interviews with knowledgeable parties and government sources. Information for corporate profiles was obtained primarily from the relevant companies, particularly large, publicly owned firms.
