Purplsoc 2015 digests and presentation

The pattern language community — followers of Christopher Alexander’s approach — is distributed globally.  I participated in PLoP 2014 at Allerton Park, Illinois last September, and then attended AsianPLoP 2015 in Tokyo last March.  I had been eyeing the PUARL (Portland Urban Architecture Research Laboratory) conference for fall 2015, but then heard that the event was being incorporated into Purplsoc for 2015.  I originally couldn’t justify a trip to Europe for the Purplsoc (Pursuit of Pattern Language for Societal Change) 2015 conference, but then its timing turned out to be back-to-back with the ISIE conference.  So, just 3 weeks before the conference, I booked a triangular routing to arrive just in time for the start on July 3, in Krems, Austria.

On the Friday, the program started with some plenary session keynotes:

  • Hermann Czech, “Remarks about the Truth and the Whole” [digest]
  • “Opening”, with Peter Baumgartner; a delegate of the Mayor of the City of Krems; Monica Kil; Christian Hanus; Hajo Neis [digest]
  • Wolfgang Stark, “Performative Patterns for Innovation: The Power of Tacit Knowing in Social Systems” [digest]

Saturday morning started with a keynote.

The rest of Saturday morning had parallel streams.  I was in the Pattern applications and practices session.

  • Hajo Neis and Perrin Wright, “Up and Out: Oregon Tsunami Wayfinding Survival Language” [digest]
  • Taichi Isaku, “The Cooking Language: Applying the Theory of Properties and Patterns into Cooking” [digest] [slides on slideshare.com

Unfolding values in places, spaces and paces: Service systems thinking and architectural theory

Prior talks on Service Systems Thinking have focused on basics.  For this year’s Symposium on Service Systems Science at the Tokyo Institute of Technology, I decided to step up the emphasis in a short presentation on some selected ideas:

  • An unfolding is a process which gets you from one stage or moment of development to the next moment of development, in the evolution of a neighborhood or in the evolution of a building;  and
  • Value is dynamic, with access consciousness ex-ante and ex-post, and phenomenological consciousness in lived experience

From the 8 practices employed by Christopher Alexander on the 1985 Eishin project, I focused on one:

  • Find systems of centers in (i) the notions in people’s minds, and (ii) the places in the land. Combine them.

These ideas are at the core of how systems thinking is intertwined with service science, and pattern languages.  Jim Kijima and Hiroshi Deguchi arranged for a videographer this year, so there’s a record of the presentation.

From Environmental Structure to Service Systems Thinking

Christopher Alexander’s work described the architecting of built physical environments.  The 1977 book A Pattern Language bears the subtitle “Towns, Buildings, Construction”.  This approach was developed in the context of architectural programming and problem seeking originating the late 1960s.  It was complemented by methods described in The Oregon Experiment, and theory in The Timeless Way of Building.  Appreciating the philosophy embraced in the practice of building environment structure leads to a lot of reading.  The challenge has been made harder by Alexander continually evolving his vocabulary and definitions throughout his career to 2012, with his last publication of The Battle for Life and Beauty of the Earth.

Service Systems Science inquires into a world that is not necessarily physical.  Is it possible to remain relatively true to the pattern language approach developed by Christopher Alexander, and extend that into a new domain labelled Service Systems Thinking?

The 21st Conference on Pattern Languages of Programs — known as PLoP, organized by the Hillside Group at Allerton Park, Illinois for September 2014 — was an opportunity to test out the idea of Service Systems Thinking amongst practitioners who have grappled with applying pattern languages to software development for over 20 years.  My contribution of writing to the Narrow Road to the Deep North (奥の細道) writer’s workshop led by Richard P. Gabriel and Jenny Quillien turned out to stretch the normal process of critical review.  The accepted paper was incomplete, overwhelming in length (since workshops usually review submissions of just a few pages), cross-disciplinary in nature, and written at level beyond an undergraduate audience.  … Read more (in a new tab)

Incubating Service Systems Thinking

Evolving the Proposal to Collaborate on a Pattern Language for Service Systems from January, the initiative has now taken on a label of Service Systems Thinking.  The presentation at the 58th Annual Meeting of the International Society for the Systems Sciences in Washington DC was recorded, so that interested parties have the option of watching or listening ideas that have developed over the past six months, and reading the slides at their leisure.  Here’s the abstract:

“Service systems thinking” is proffered as a label for an emerging body of work that: (i) builds on social systems thinking (i.e. socio-psychological, socio-technical and socio-ecological systems perspectives) to advance a transdisciplinary appreciation of service systems science, management, engineering and design; (ii) explores opportunities to enrich Alexanderian patterns and categorized pattern catalogs into a generative pattern language; and (iii) collaborates on new platforms, moving from inductive-consensual wiki pages to a multiple-perspectives (federated) wiki.

The session was conducted in two parts, each of about 90 minutes.  The first part had a soft start playing some videos on the Smallest Federated Wiki by Ward Cunningham, since participants were coming back from lunch in another building.  The presentation alternated between projected slides, and live content on the federated wiki at http://fed.coevolving.com/view/welcome-visitors/view/service-systems-thinking.  The agenda covered:

  • 1. Service Systems Thinking, In Brief
    • 1.1 An intentional representation
    • 1.2 An object-process representation
  • 2. Conversations for Orientation
    • 2.1 Systems thinking
    • 2.2 SSMED (Service Science, Management, Engineering and Design
    • 2.3 Generative Pattern Language
    • 2.4 Multiple Perspectives Open Collaboration

Scenarios and Design: Instigating Change, Methods Framing, Scenario-Buffered Design

At the Oxford Futures Forum 2014, hosted by the Saïd Business School, I was invited to be a participant in a generative dialogue.  Each of the invitees was requested to submit a 250-word abstract and an image four months ahead of the event.  In two days, we had three group discussion meetings, where individuals were free to go to other groups (or form new groups) according to the ideas emerging from the dialogue.

This event runs on the Chatham House Rule:

When a meeting, or part thereof, is held under the Chatham House Rule, participants are free to use the information received, but neither the identity nor the affiliation of the speaker(s), nor that of any other participant, may be revealed.

Further, in a generative dialogue, ideas flow and merge as participant learn from each other, so representations related to people outside of the involved group don’t get a full appreciation for the unfolding learning.  Having been a participant in a series of prior IFSR Conversations that similarly focus on generative dialogue, any describing of the experience turns out somewhat inadequate.  The most that can be related to others are “proceedings”, where some of the ideas in progress are captured.  As a participant in Oxford Futures Forum, I was involved in three rounds of conversations, which can be roughly framed as:

  • design and scenarios to instigate change (as an introductory clustering to start the first round);
  • methods framing (as the emergent theme from the first round to go into a second round); and
  • scenario-buffered design (as the label that was presented as the conclusion of the third round).

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?
