Links in the Chain Why Mature Systems Engineering is Needed Richard Conn Microsoft December 2003

Links in the Chain - Systems Engineering2 Motivation – Software-Intensive Systems Engineering More and more, systems are becoming software intensive, containing millions of lines of code! People have to work in teams to produce many kinds of products – one person cannot do it alone in most cases!

Links in the Chain - Systems Engineering3 The Systems We Build  Business-Critical  Financial  Infrastructure  Mission-Critical  Business-Critical  Domain-Specific  Safety-Critical  Lives are at stake! More and more, failure is NOT an option!

Links in the Chain - Systems Engineering10 Context  Maturity is about …  People  Following a disciplined process  To create software- intensive products

Links in the Chain - Systems Engineering11 People are … MMMMembers of a Team AAAAssigned one or more leadership/management roles TTTTeam Leader DDDDevelopment Manager PPPPlanning Manager QQQQuality/Process Manager SSSSupport Manager EEEEach role has a set of specific responsibilities TTTThese responsibilities vary from process to process RRRRecurring responsibilities, which are repeated in all processes, also exist

Links in the Chain - Systems Engineering12 The Process is …  A set of activities for producing a product or set of products  Processes may also contain other processes  Each process has at least –  An entry criteria  A set of activities or processes to follow  A set of products to be consumed  A set of products to be created or modified  An owner (who can change it), a controller (who runs it)  An exit criteria

Links in the Chain - Systems Engineering13 The Products are …  Software (in the context of Software Engineering)  Code (obviously)  Documents  Data  Hardware  Created by people  Used by people

Links in the Chain - Systems Engineering22 New World Order Our society depends on software for its day-to-day existence, and the failure of software systems is increasingly becoming intolerable. Software Engineering is entering universities around the world, becoming a necessary component of an education in computer science and information technology.  Universities such as MIT, Carnegie Mellon University, and Stanford have had software engineering programs  Computing Curriculum 2001 of the Association for Computing Machinery’s Special Interest Group in Computer Science Education contains Software Engineering Knowledge Units  Software Engineering program accreditation by the Accreditation Board for Engineering and Technology (ABET) began in the Fall of 2002  Systems Engineering is coming!
