Negotiating Order with Generative Pattern Language

Positioning “A Pattern Language” more like “Creating Order of”, then “The Timeless Way of Building” more like “Negotiating Order with”, was a productive framing to discuss the systems theory inside Christopher Alexander’s thinking (as well as positioning “The Nature of Order“).

The purpose of a workshop on “Negotiating Order with Generative Pattern Language” at PLoP 2017 was to open up discussions that could deepen the foundational understanding in linkages between pattern language and systems thinking. At least three of us routed to Vancouver BC for a Monday morning start, in a quick trip from the Purplsoc meeting in Austria that finished on Saturday.  The PLoP program emphasizing writers’ workshops meant that our 90-minute dialogue didn’t conflict with any presentations.

On the audio recording, active participants in the sensemaking included Helene Finidori and Christian Kohls.  With a more relaxed pace, the open time after the slides were completed allowed some pattern language novices to also have questions answered.

The frame for discussion was slides that had previously been posted on the Coevolving Commons.

The digital audio recording has been matched up with slides, for a less ambiguous viewing as a web video.

Exploring the Context of Pattern Languages

Pattern language is not for wicked problems, said Max Jacobson, coauthor with Christopher Alexander of the 1977 A Pattern Language: Towns, Building, Construction.  In addition, the conventional definition of an Alexandrian pattern as “a solution to a problem in context” when applied to social change might better use the term “intervention”, rather than “solution”.

These are two of the major ideas that emerged at Purplsoc 2017 conference last October.  A 90-minute workshop was run in parallel with other breakouts.

For about the first hour, vocal participants included Max Jacobson (who had given a plenary talk on “A Building is not a Turkish Carpet“), Christian Kohls (who gave a plenary talk on “Patterns for Creative Space“) and Peter Baumgarnter (one of the Purlpsoc chairs).

As an impetus to discussion, we stepped through slides that had been posted on the Coevolving Commons.

For people who would like the next-best experience to being there, the slides have now been matched up with the digital audio recording, for viewing as a web video.

For devices decoupled from the Internet, downloadable video files are portable.

Acts of representation with systems thinking (OCADU 2017/03)

For the “Understanding Systems & Systemic Design” course in the program for the Master of Design in Strategic Foresight and Innovation at OCAD University, the lecture slides were the same for both the full-time cohort on March 8 and part-time cohort on March 9, while the oral presentation varied.  The target, in about 90 minutes, was to cover at least 4 of 5 sections, from:

  • 1. Architecting ↔ designing
  • 2. Service systems ← production systems
  • 3. Affordances ↔ pattern language
  • 4. Ecological anthropology ← teleology
  • 5. Inquiring systems ↔ methods

The students were alerted that some of the arrows in the section headings were double-headed, and some were single-headed — with specific meanings.  For each day, the classroom audio was recorded.  That digital audio has now been synchronized with slides that had previously been posted on the Coevolving Commons.

This session was #8 of 15 lectures for the OCADU SFI students.  They had already done some basic reading on systems approaches.  Since they were working towards a Major Research Project (a lighter weight form of a thesis) for their Master of Design degree, my overall agenda for this lecture was to have them reflect on acts of representation.   Systems have already been represented to them in a variety of forms:  textually, orally and visually.  For their Major Research Projects, they would be creating detailed representations, as ways of having their audience appreciate the in-depth study of the world and issues selected for the term.

Service Systems Thinking, with Generative Pattern Language (Metropolia 2016/12)

Teaching methods in a master’s class is different from lecturing on theory.  There’s more emphasis on how, with why subsequently provided as the need for that arises.  Since I had given a dense 20-minute theoretical talk in the month earlier, the invitation from Satu Teerikangas to the program in International Service Business Management was an opportunity to stretch out at a more leisurely pace with students, as they’re preparing for thesis work.

The 3 hours class was conducted in parts:

  • (A) Introductory lecturing for 85 minutes on …
    • 1. Architecting versus designing
    • 2. Alexandrian example → services
  • (B) Faciliated learning, for 55 minutes, with an …
    • 3. Exercise:  trying out pattern language
  • (C) Contextual lecturing for 23 minutes, on …
    • 4. Systems thinking + service systems
    • 5. Ignorance and errors

The classroom interaction was recorded in audio, and is complemented by slides that had been posted on the Coevolving Commons.

Pattern Manual for Service Systems Thinking

At the PUARL Conference 2016, a proposal was made on adapting pattern language for service systems thinking.  In 1967, Christopher Alexander published Pattern Manual at the founding of the Center for Environmental Structure, describing a pattern format for physical built environments.  While we can learn a lot from the nearly 50 years work originating at the CES, service systems have features beyond physicality that suggest reconsidering some of the foundations of pattern language.

An article for discussion was accepted into the proceedings for the PUARL conference.  The 20-minute presentation quickly covered the following topics:

  • 1. Pattern Manual 1967 + Service Systems
  • 2. Alexandrian example → services
  • 3. Methods clarified since 1973
  • 4. A new format:  amplifying, rephilosophizing, reinterpreting prior doxa
  • 5. Generating and legitimizing in communities

An Introduction to Service Systems Thinking

A lecture for the Master’s Program in Industrial Management at Helsinki Metropolia University of Applied Sciences was an opportunity to talk about the research that has been brewing over the past 18+ months, from the basics.  These students were unlikely to have heard much about (i) systems thinking; (ii) service systems, (iii) generative pattern language, or (iv) federated wiki.

Coming to Metropolia in 2015 was like a return home.  In 2006, the institution was named Helsinki Polytechnic Stadia, and I collaborated on starting up the curriculum as part of the Rendez project.  In recent years, I haven’t been so involved.  As I was planning a trip to Europe this fall, I discovered that Satu Teerikangas had returned from teaching at UCL in the UK to Finland, becoming the Head of the Industrial Management Program.  My itinerary coincided well with the course dates, so I pulled together a presentation from the evolving ideas over the last year.  The audience would be a combination of students from the Industrial Management program and the Logistics program.

The session was conducted in two parts, each slightly under 60 minutes.  The first part covered:

  • 1. What could Service Systems Thinking be?
  • 2. Systems Thinking
  • 3. SSMED (Service Science, Management, Engineering and Design)
