Lars Rossen is a Hewlett Packard Enterprise Fellow working as the chief cross-portfolio architect in the HPE Software CTO office. Lars created the first version of the IT4IT™ Reference Architecture which formed the basis for the standard in The Open Group, and Lars continues to be the lead architect for the IT4IT initiative. In Hewlett Packard Enterprise Software this forms a foundation for the development of the Hybrid IT management portfolio of products. Before joining the CTO organization in 2015, Lars worked in the Software portfolio architecture and strategy team and has had many leading roles in defining and progressing the current IT management solution portfolio. Before his current IT4IT role, Lars was part of the core team that defined HPEs CloudSystem strategy and associated solution portfolio.

Prior to joining the portfolio strategy office, Lars headed up HPE’s Operational Support System practice for Europe, Middle East and Africa. He played an important role in linking the vision of eTOM, NGOSS, and ITIL into practical solutions through HP’s Integrated Service Management blueprint. That design served as the basis for how many cloud services are managed today.

Lars was a researcher at the University of Denmark in the area of formal methods for computing before becoming CTO at Netman, a telecoms ISV and Consultancy Company. HP acquired Netman in 2004 and structured it into an operation support systems expertise centre.

Lars holds an MS in engineering, an executive MBA with focus on technology management, and a PhD in computer science from the technical University of Denmark.
