The seventh National Conference INCOSEIL 2013 Enterprise System

The seventh National Conference INCOSE_IL 2013 Enterprise System Engineering Challenges Miri Sitton ∙ Yoram Reich Tel Aviv University 1 March 2013 Enterprise SE Challenges

Research Objective To define enterprise system engineering challenges and review relevant state-of-the-art research and practice 2 March 2013 Enterprise SE Challenges

SE Definition An interdisciplinary approach and means to enable the realization of successful systems • Focus on system • Early in the development cycle 3 March 2013 Enterprise SE Challenges

Enterprise SE Definition An interdisciplinary approach and means to enable the realization of successful enterprises • Focus on enterprise operational processes • On going – No early stage for planning – Enterprise continuity constraint 4 March 2013 Enterprise SE Challenges

Property Number of components Coordination between components 5 March 2013 SE Enterprise SE Up to tens sub- Up to hundreds systems unsynchronized & dynamic systems Planned in Enforced by advance connectivity design phase infrastructure and standards Enterprise SE Challenges

Property Operational requirements definition Design focus Operational install 6 March 2013 SE System user Enterprise SE No user or responsibility System Cross-Enterprise capabilities processes System Gradual installation replacing - enterprise processes continuity Enterprise SE Challenges

General example Sensor A Sensor B System D Sensor C System X Sensor Y 7 March 2013 Enterprise SE Challenges

Transportation arena example Closed road School road Local Or …optimum Free market Vs. Global failure optimum (chaos) 8 March 2013 Enterprise SE Challenges

The Challenge To establish enterprise system-engineering processes and a coordinated architecture driven from the operational processes, to support Interoperability as part of enterprise strategy generation 9 March 2013 Enterprise SE Challenges

The HKM Framework Built-in system engineering done at project level 10 March 2013

State of the Art • Product, system and SOS engineering • • • 11 Built-in Business systems engineering • Enterprise Architecture • ZACHMAN Framework • TOGAF • DODAF Supply Chain Systems Engineering? March 2013 Enterprise SE Challenges

Major Gaps • Product, system and SOS engineering • • Do not support unsynchronized effort Business systems engineering 12 • Very complicated to implement • Highly abstract and generic • Not driven from operational processes • No information flow presentation (only static) March 2013 Enterprise SE Challenges

Enterprise SE Foundations • Multi-disciplinary teams of operational and engineering workgroups is essential • Reuse of enterprise’s assets • Operational processes continuity • SE layers: y cu r e yb Se t ri In te gr at io n t C March 2013 ito rin g Architecture M on n io at rm ty fo afe S In 13 Te s Connectivity Infrs.

Top down & Bottom up Top down (lighthouse) • • • Define operational vision (Gradual) Define policy and holistic architecture Define compliance standard Bottom up • • • 14 COTS SYS - Of the Shelve systems Win-Win motivation (private-government) Integration compliance test March 2013 Enterprise SE Challenges

ITS Ecosystem ou Traffic Control Complexity: • Arrays of systems Public technologies (Vehicle, Roads) • Different Transp. • Unmanaged development. The challenge Creating cross-organizational SE • End users diversity processes and environment to support continuous development, integration &Transp. dissemination of ITS Ministry projects within coherent Main problems: architectural design, social • Non coherent S. E. culture governmental & business policies • Multiple effort on the. Content same niche • Lack of users-value. Services activities • Unclear cut between Private & Public investments areas March 2013 15

Summary • Enterprise SE is much more complex and dynamic than SE • Main gaps in existing State-of-the-Art • Do not support unsynchronized effort • Not driven from operational processes • The emerging challenge is the need to establish enterprise system-engineering processes and a coordinated architecture driven from the operational processes 16 March 2013 Enterprise SE Challenges
