The Hillside Mission
The mission of the Hillside Group is to improve the quality of life and society as a whole. This includes architects, developers, managers, owners, workers, educators, students, and more. Understanding and helping the human element is critical for achieving success. The Hillside Group believes in making processes and design more humane by paying attention to real people and existing practices.
The Hillside Group promotes the use of patterns and pattern languages to record, analyze, and share knowledge to help achieve its mission. The Hillside Group sponsors a variety of activities to achieve this mission—organizing workshops, hosting PLoP (pattern) conferences, and producing publications for discussing, recording, and documenting successful practices.
The Hillside Group supports many different conferences such as: PLoP, EuroPLoP, AsianPLoP, VikingPLoP, SugarLoafPLoP, and ChiliPLoP. These conferences focus on writing groups to better improve patterns through group exposure. Each conference offers advanced topics for the more adept pattern writers. Participants have the opportunity to refine and extend their patterns with help from knowledgeable and sympathetic patterns enthusiasts.

MaryLynn Manns – “Imagination Run Wild” (This email address is being protected from spambots. You need JavaScript enabled to view it.)
The Conference on Pattern Languages of Programs, People, and Practices (PLoP) was established thirty years ago by The Hillside Group. It gathers people who wish to improve the quality of life through designing and using social and technical systems in a more humane way, effectively articulating professional and other creative practices, and sharing this tacit knowledge more broadly. To achieve this, the conference promotes the use of patterns and pattern languages, as well as the underlying theory of the nature of order. Originating in the work of Christopher Alexander on building architecture, these ideas have been further developed in computer science, fundamentally changing the perception of software development. Much of the pioneering work in this area originated at this and other PLoP conferences throughout the world. Patterns and pattern languages have expanded to many other areas, including art, well-being, learning, psychology, organizational development and change, sociology, and anthropology. PLoP 2024 encourages a variety of submissions regardless of the area they target.
We're excited that this year's conference will be held at Skamania Lodge in Stevenson, Washington in the Columbia River Gorge National Scenic Area.
Paper Submissions
PLoP 2024 welcomes papers describing patterns and pattern languages, experience reports, essays, empirical evaluations, reflections, etc. After the initial screening by the program committee, you will get the opportunity to improve your paper under the guidance of a dedicated shepherd. If your paper is accepted at the conference, it will be discussed in a writers' workshop session with other authors and participants. Based on what you learn at writers' workshops, you will make final improvements to your paper after the conference and submit it for the proceedings.
If you have any questions about paper submissions, This email address is being protected from spambots. You need JavaScript enabled to view it..
Other Submissions: Let Your "Imagination Run Wild"
PLoP 2024 encourages other types of sessions too. Let your imagination run wild and propose something! For example, focus groups or workshops bring together people interested in a challenging topic to discuss it or even experience it. Lightning talks are a great opportunity to convey recent results, pose intriguing questions, or explore partially formed ideas that would benefit from a broader discussion in just five minutes plus discussion. Reports from any of these sessions may be included in the conference proceedings (subject to review).
The conference organizers are open to receiving a variety of session types and activities. If you wish to propose an activity that does not fit into any of the formats mentioned in this call, This email address is being protected from spambots. You need JavaScript enabled to view it. to discuss it.

10th Asian Conference on Pattern Languages of Programs, People, and Practices
Call for Submissions and Participation for AsianPLoP 2024
Feb. 28 - Mar. 3, 2024 — Fujisawa City, Kanagawa Prefecture, Japan
About AsianPLoP 2024
When people create something or implement a practice, they utilize knowledge learned from their past experiences. However, this knowledge of design and practice is usually confined to the individual, making it inaccessible to others. What if we could articulate this tacit knowledge and share it with others? This is where Pattern Languages come into play. Originally developed as a method to share knowledge about designing good towns and buildings, it was later used to share expertise in excellent software design. Subsequently, Pattern Languages have been created across a wide range of fields to articulate and share knowledge in professional and everyday practices.AsianPLoP is a conference held in Asia, bringing together people interested in articulating and sharing knowledge of good design and practices across various fields. During the conference, participants bring their short papers and exchange feedback and further ideas to improve each other’s work. This fosters a collaborative environment for facilitating the creation of pattern languages to empower individuals and communities for a better future. Your participation and contributions are highly anticipated, as we embark on this collective journey towards a better future.

Call for Submissions
1. Short Papers (Approximately 3 Pages or longer like 10 pages) in English or Japanese
We are seeking short papers related to patterns or pattern languages in specific fields, as well as essays on their application and creation methods. We welcome submissions not only of completed works but also those in progress or in the conceptual stage. Authors can use any format for their papers, whether in English or Japanese. We also welcome essays and other papers not in pattern form, such as essays, classical technical papers, or articles. Let’s appreciate and enhance each other’s work through participant interaction. In some special cases, larger papers could be accepted, but the authors should justify why they think this is the case when submitting the paper.
2. Focus Groups/Workshops
We invite proposals for focus groups that delve into specific themes, as well as workshops where participants create or experience something hands-on. The duration of these sessions is expected to be approximately one hour.
Paper Submission Process
The core of AsianPLoP, as with all PLoP conferences, is the Writers’ Workshop. This workshop is where participants discuss improving their papers through constructive feedback. Before papers are accepted for a Writers’ Workshop, they are shepherded. Shepherding is an iterative process, where an experienced author discusses the submission with its authors to refine the paper prior to the conference. To be accepted into the Writers’ Workshop, papers must be improved through this shepherding process. As AsianPLoP 2024 is calling for Short Papers, the Shepherding process is simplified into 1-2 rounds, which we refer to as Mini-Shepherding for this conference. After the conference, authors have the opportunity to submit their final version, revised based on the comments received at the Writers’ Workshop. The submitted papers will be published on the Hillside website.

The premier Asian conference on
Pattern Languages of Programs
AsianPLoP solicits paper submissions written in both of English and Japanese; English papers and Japanese ones will be discussed in different sessions. Both practitioners from the industry and academics are invited to submit their papers. The conference solicits the papers for the following different sessions.
- Writers' Workshop - papers that document patterns and pattern languages will be workshopped in the traditional PLoP format.
- Technology Workshop - papers that explore theories, techniques, applications, tools and case studies in patterns and related areas such as agile developments.
- Writing Group - papers of newcomers who want to learn how to better elaborate an idea intended to evolve to a pattern or pattern language. This is more like a hands-on tutorial on writing patterns.
Previous Asian Pacific Conferences
While this is the first AsianPLoP, The Hillside Group has sponsored PLoP conferences located in Asian Pacific region in the past, including the MensorePLoP and KoalaPLoP.
We have information on those conferences here for posterity.
Bridging the World!
Software developers have long observed that certain themes recur and endure across different applications and systems. The emerging interest in patterns represents an effort to catalog and communicate these themes and motives-to provide handbooks of proven solutions to common problems. MensorePLoP brings together researchers and practitioners whose interests span a remarkably broad range of topics, who share an interest in exploring the power of the pattern form. MensorePLoP invites you to add your expertise to the growing corpus of patterns. MensorePLoP focuses on improving the expression of patterns.
MensorePLoP was held at Hotel Moon Beach, Okinawa, Japan. This was the first attempt to hold this kind of conference in a subtropical climate and insular geological structure.
Australian Conference on Pattern Languages of Programs
KoalaPLoPTM was hosted near Melbourne Australia and is open to pattern authors, pattern users, and software designers and developers from around the world. The conference was last hosted in 2002. It ran for three conference cycles.
