Reflexion
Reflexion
The next step in utilizing high-tech systems data
Introduction
React to Effects Fast by Learning, Evaluation, and eXtracted InformatiON
Reflexion project aims at supporting the emerging high-tech industry paradigm shift from selling ‘boxes’ to supporting ‘integrated solutions’, by using operational data to improve the development lifecycles, maintenance and troubleshooting of products. This leads to faster time-to-market, lower costs and greater competitiveness.
Reflexion objectives are
Reacting to unforeseen problems or emerging needs in a speedy and cost-effective way by augmenting products with an introspective layer of data sensing and data analytics.
Thereby creating value out of the high-tech system’s operational data which for now is still characterized by legacy choices on infrastructural and analytical approaches.
Propagating this knowledge (automatically) back into the product development lifecycle and the service & maintenance flow.
