Christopher Alexander tells us, “Patterns must not be etched in stone; rather, they must grow as the users gain new experiences.” As co-author of the Fearless Change pattern language, Mary Lynn has steadily worked on this language with Linda Rising for almost 20 years. She will share her insights on keeping a pattern language alive and updated with changes to existing patterns and additions of new patterns. To do this, she will use the patterns in Fearless Change to explain how other authors can use these tools to keep their patterns growing and evolving, rather than being “etched in stone”.

Mary Lynn Manns, PhD is a professor of Management Information Systems at the University of North Carolina in beautiful Asheville, NC. She has taught students from freshman through graduate level how to “change the world” and was recently awarded Distinguished Professor of Social Relations for her work in change leadership. Her books, co-authored with Linda Rising, are Fearless Change: Patterns for Introducing New Ideas (2005) and More Fearless Change: Strategies for Making Your Ideas Happen (2015). Mary Lynn has given numerous presentations throughout the world in organizations that include Microsoft, Proctor & Gamble, and amazon.com. But one of her favorites was a 2013 university commencement address in which she brought graduates to their feet to take the first steps towards changing the world by doing a little Zumba dancing.

Is “software engineering” really engineering yet? The term was coined in 1968 to call attention to problems with software production. Both theory and practice for software have evolved since then, but do we by now have a true engineering discipline? Classical engineering disciplines have emerged from craft practice and commercialization through the infusion of codified knowledge and science. Using this emergence pattern as a point of reference, I will sketch the evolution of software engineering, drawing on civil engineering and software architecture for examples that show the progressive codification of informal knowledge toward rigorous models and tools. This will provide the basis for assessing the maturity of the field and identifying our next challenges.

The work of Christopher Alexander influenced the classic Design Patterns book as well as the software patterns community and a half a dozen or so conferences a year, PLoPs. Alexander is an architect interested in understanding the nature of beauty and its objective reality, which led to the publication of his gargantuan four-book essay, The Nature of Order. In it he attempts nothing short of proposing a new scientific method and cosmology to replace the Cartesian / reductionist / mechanistic approach to science; and while he’s at it, he proposes a common sense way to understand the incomprehensible mathematics of quantum mechanics (along the way he also unifies science, art, and the spiritual).

The Nature of Order focuses on centers, life, and wholeness, the fundamental process, and structure-preserving transformations. Core to this is an evolutionary process that proposes that complex systems do not spring into existence completely formed, rather they evolve through a lot of small steps. He discusses a series of 10 structure-enhancing actions that he claims will always intensify the life and wholeness of a thing. Recently, Iba laboratory proposed other type of fundamental properties for human actions: 24 fundamental behavioral properties.

This workshop will examine these evolutionary generative processes and how they can be related to other areas such as building and sustaining community. This workshop - not the workshop itself but the ideas in it - will leave you confused, profoundly smarter, reeling, in despair, and suffused by joy about what is possible for us.

Layering is hard. Patterns around layering have been created (e.g. shearing layers and layer pattern itself) and many books describe layering. But there is a lack of a pattern language in this field that can help architects to design a better layering. In our paper “Logical Layering Heuristic” (submitted to PLoP’15) we propose a method that provides a structured approach for coming to a good layering. However, behind this method (or high-level pattern) there certainly are hiding some patterns that, we believe, are the reasons for why the method is useful. The goal of this focus group is to identify both already described patterns and possible pattern candidates in the method (and in the good application of layering itself) as a first step towards a pattern language for layering. The focus hereby is holistic, we're interested in ALL possibly relevant aspects of layering, incl. architectural/design patterns, organizational patterns, collaboration patterns, requirements patterns etc., and their relations.

Goals include, but are not limited to... a) Discover existing patterns that can be used in this pattern language; b) Pinpoint candidate patterns that can be expanded upon in new patterns descriptions.

Main discussion topics: a) What existing patterns can be included in the pattern language? b) What are new patterns that should be part of this language?

Participants should have experience with the application of layering in software architectures. It also would be good if they have read the paper “Logical Layering Heuristic”. A link to the article will be provided before the conference.

Pattern authors often struggle to find relevant design patterns across many sources ranging from books, papers, conferences, journals, and online repositories. Many attempts to build a central consolidated design pattern repository failed. Some possible explanations include: (a) pattern authors disagree on pattern formats to support; (b) a central repository raises thorny questions about design pattern ownership and attribution; (c) such a large and ambitious repository requires broad community support. In this workshop, an open, collaborative pattern repository is discussed as a possible solution to address previous challenges. We seek to understand the challenges and opportunities from a PLoP point of view.

The workshop is intended for design pattern authors and users. Its main goal is to introduce the open, collaborative design pattern repository and will involve a short presentation of the facilitators' work, followed by an interactive discussion with the participants. Feedback from the participants can help to further refine the repository’s framework and identify different strategies that can encourage stakeholders to contribute and collaborate in building the repository.

Writer’s Workshop (WW) is a method to review, evaluate and improve each other’s pattern, which is widely accepted in xPLoP conference including this EuroPLoP. However, there are several problem existing in traditional WW such as “poor experience of moderator”, “poor knowledge of participants” or “poor pattern accepted”. Detail discussion of these problem could be found in our work. As a solution to these “ad hoc” reviewing, we suggest utilizing some software reading techniques such as Checklist-Based Reading (CBR) or Perspective-Based Reading (PBR) into WW. In this focus group, we are going to discuss it together by conducting a mini WW.

Key Idea: We have conducted experiments in this topic several times before. Based on those result, we will hold this focus group in the idea of “Customized checklist” and “Using checklist as a remainder”. Thus to say, participants will receive checklists made for reviewing target paper, and keep the contents in mind during reading and discussion, as a remainder. Detail process could be found in this paper.

Target participants: We prefer to have newer author join us, as we believe that our approach will have much effect on them. Of course, experts are also welcomed. We are willing to listen to your opinion on this approach and discuss together.

Software engineering research follows a variety of paradigms, including empirical studies, formal analysis, system building, systematic literature review, and qualitative studies. Unfortunately, the field has generally not been very explicit about how research in these styles should be reported, especially about the differences between reports of research in different styles. The problem lies not just in the surface qualities of the papers, but in the deep structure -- the scientific arguments.

Careful reading of good papers reveals considerable regularity. This calls out for a pattern language that captures the recurring elements: identifying the settings where they are appropriate, the ground rules for carrying them out, and suitable ways to use them in combination.

The bare bones of such a Pattern Language for Software Engineering Research Papers are under development at SEresearchpatterns.org. There are patterns that capture the structure of the scientific argument and the way it maps to the overall structure of the paper. There are patterns for elements within papers (e.g., traceability from claim to result, related work) that are used in numerous types of papers. To get started, it focuses on 8-10 page conference papers.

The goal of this focus group is to put some meat on those bare bones. That means identifying patterns for more paradigms, recognizing commonalities and differences, and refining the levels of granularity in the language. We will try to capture the essence of the resulting patterns but probably will not have time to write them in detail.

It would be very helpful if participants would choose three or four papers in their preferred research style and sketch the patterns that they find in the style of SEresearchpatterns.org.

A recent paper did an experiment to show that security patterns are not very useful. However, they did not consider methodologies, only patterns in isolation.

This group will intend to discuss the following questions relevant to the use of security patterns:

1. Do we have good methodologies to build secure systems using patterns? If so, why are they not used?
2. Can we merge or combine some of them to have a complete (with tools) and tested methodology?
3. Can we have a unified catalog? At least, unified pattern descriptions. We started to work in this direction in EuroPLoP.

I think there is plenty to talk about these topics but I will accept suggestions for other relevant questions. The idea is for researchers on security patterns to exchange ideas and start possible collaborations.
