A Proposal for Collaboration on a Pattern Language for Service Systems

A meeting of systems scientists and systems engineers together as the Systems Science Working Group at the INCOSE International Workshop 2014 provided a forum for “a proposal for collaboration on a pattern language for service systems (science, management, engineering and design)”.  The title is deliberately long, and required some hours to unpack the content in the slide deck.

A Proposal for Collaboration on a Pattern Language for Service Systems (Science, Management, Engineering and Design)

The initiative has been presented as ambitious.  Writing a (good) pattern language is non-trivial.  The originator of the pattern language, Christopher Alexander, published his first work in 1968, and then spent 9 years in collaboration until the 1977 release of the landmark A Pattern Language: Towns, Building, Construction.  In a 2010 interview, Alexander was asked about his perception on similar efforts.

[Rob Hoskins]: What’s been your opinion of subsequent peoples’ attempts at doing Pattern Languages – I’ve seen a couple of different ones, have you seen many?

[Christopher Alexander]:  Some. They’re not that good. The reason I say that is that the people who’ve attempted to work with Pattern Languages, think about them, but are not conscious of the role of morphological elegance in the unfolding. In a biological case, they always are elegant and the unfolding morphology is a sort of magic. But it’s very simple.  It’s not as if it’s magic because it’s complicated, it’s just … like that.

[Rob Hoskins]:  I guess when we were talking before about how a Pattern Language goes from the large down to the small, maybe when we were talking about it as going outwards maybe it is more like an unfolding process?

[Christopher Alexander]:   I think it is yes. The business of going from the large to the small was more for convenience….you could make sense of the book most easily like that but it isn’t necessarily the way to actually do it.

While contributors to this project can learn from prior art in pattern languages, there’s some basic contexts to be understood and appreciated.

A. Service systems (science, management, engineering and design)

Service systems are described in the context of the 2008 report on “Succeeding through service innovation” by the Cambridge IfM and IBM.  The science, management, engineering and design perspectives are from the 2009 Spohrer and Kwan article on”Service Science, Management, Engineering, and Design (SSMED): An Emerging Discipline — Outline & References”, with ten basic concepts underlying a service systems worldview.

B. Pattern language (c.f. pattern catalog)

The working of a pattern language is described with extract of the 1977 book A Pattern Language, with 127 INITIMACY GRADIENT.  The history of the Hillside Group, with a software (design) pattern (definition) illustrates application in a domain other than the built environment.  The variety of forms of writing patterns has been described by Martin Fowler.  Ties between pattern language and systems thinking are drawn by James O. Coplien and Neil Harrison 2004 and by Werner Ulrich 2006.  Christopher Alexander’s “Quality without a Name” is described in Richard P. Gabriel 1996.  Addition domains with ongoing work with pattern languages are evident in Scrum, in group facilitation processes, and in communications in the public sphere.

C. A starter set?  7 conditions from service systems science

Panel on Service Systems and Systems Sciences in the Twenty-First Century, INCOSE International Symposium 2010

Since 2008, I’ve been conducting research on service systems and the systems sciences, with my core collaborators Gary Metcalf, Jennifer Wilby and Kyoichi (Jim) Kijima.  As senior members of the International Society for the Systems Sciences, we’ve been working towards a more formal association with the International Council on Systems Engineering, and with the Systems Science Working Group in particular.  Our organizations came together for the first time in the INCOSE International Symposium 2010, in Chicago.

For the International Symposium, our contribution was a panel on our progress in researching service systems and the systems sciences, with position papers and presentation slides discussed in Chicago in July.  After that meeting, a summary of the session was reported in an article published in INCOSE Insight in October.

The publications page on this web site includes links to the:

Our core group will be continuing our research into 2011, with a two-day co-learning workshop at the International Workshop 2011 in Phoenix, Arizona.  The linkages between the systems sciences and systems engineering should continue to develop.
