See Jim Brown’s contributed article in Advantage for the Product Lifecycle, SAP Extends Technical Publishing to the Enterprise. The article explains the opportunity for manufacturers to improve their technical communications processes with solutions like Right Hemisphere, including Dassault System’s 3DVIA (Composer), Anark, PTC’s Arbortext, Cortona3D, Immersive Design, Lattice Technology, Quadrispace, and others. Beyond that, the article points out SAP’s unique opportunity to integrate advanced publication capabilities from Right Hemisphere further into the enterprise.
Note: SAP acquired Right Hemisphere in 2011
