'''Process development execution systems''' ('''PDES''') are [[software systemssystem]]s used to guide the development of high-tech manufacturing technologies like [[semiconductor]] manufacturing, [[MEMS]] manufacturing, [[photovoltaics]] manufacturing, [[biomedical]] devices or [[nanoparticle]] manufacturing. Software systems of this kind have similarities to [[product lifecycle management]] (PLM) systems. They guide the development of new or improved technologies from its conception, through development and into manufacturing. Furthermore they borrow on concepts of [[manufacturing execution systems]] (MES) systems but tailor them for R&D rather than for production. PDES integrate people (with different backgrounds from potentially different legal entities), data (from diverse sources), information, knowledge and business processes.
