Enterprise Systems Engineering One Systems Engineer's View Stephen J. Sutton, P.E. Enterprise Systems Engineering (ESE) Panel Presentation & Discussion INCOSE Chesapeake Chapter 15 March 2007 The opinions presented tonight represent my personal views and are not those of my employer or INCOSE

Topics Definition Challenges Skills and Tools

ESE Definition Engineering for the lifecycle of a complex entity –An organization (company, agency, a government) –A multi-national project (GEOSS) This is not engineering of a well defined system with all the constraints are clear and bounded

Challenges Recognize that ESE corresponds to activities for re-engineering, strategic planning – not all technology-focused engineering Following a process and method Doing the hard work so that subordinate activities will be successful Finding the right people

Skills and Tools An ESEs Characteristics –Knows what questions to ask and information to capture –Look at the system in its environment –Work with people –Can identify or elicit needs (goals, missions, capabilities, MOEs, metrics….) –Addresses multiple levels of abstraction –Uses tools effectively –Willing to live with not getting to the gory details of technology and implementation – but having to understand the technology and implications for implementation: Concentration on activities, information, products and not on the physicality of the enterprise –Willing to live with uncertainty

Strata of Enterprise Transformations Transformation 1 Transformation 2 Transformation 3 Transformation 4 External Environmental Constraints Lines of Business/Business Functions/Products and Services Top Level Organization Structure/Business Geopgraphy Strategic Plans/Measures & Metrics/Timelines General Business Rules Operational View (capabilities, information/flows, products, services, processes) Expanded Organization Structure/Locations & Relationships Business Master Plan/Master Schedules Expanded Business Rules Systems View (Master Transition Plan, Segment Definition) Capabilities Roadmaps Roles and Responsibilities Detailed Business Rules Material (Systems) and Non-material (e.g., doctrine) solutions

Summary Enterprise engineering poses interesting challenges for an SE SE is SE but the enterprise context presents differences Certain skills take forefront
