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.

Pattern Books

The Design Patterns Book Series showcases many patterns from PLoP conferences and leading experts in the patterns field.

See our Pattern Book Library filled with over 80 Pattern related books.

Authors, how was your last shepherding experience?
Here is a scale of shepherding excellence to think about.

Shepherds, where do you think your "sheep" would rate you?

1. Oh, I had a shepherd?

2. My shepherd made contact, and promised to send comments.

3. My shepherd actually sent a set of comments.

4. My shepherd was positive and supportive.

5. My shepherd was prompt.

6. The comments from my shepherd had substance; not just grammar and wording.

7. My shepherd gave me two or more sets of comments.

8. I learned more about patterns from my shepherd.

9. I learned more about my own topic.

10. My shepherd helped me learn more about myself.

Shepherds, how well did your "sheep" do?

Authors, where do you think your shepherd would rate you?

1. Never heard from the author.

2. The author apologized for not responding.

3. Got one revision -- just before the shepherding deadline.

4. Ignored all my suggestions.

5. Was clueless.

6. Really did try to improve the patterns.

7. Sent two or three revisions.

8. I learned more about patterns from the shepherding experience.

The Pattern community is unique in the individual mentoring we give to each other through shepherding. Many of us have learned a great deal from our shepherds. Many of us enjoy serving as shepherds because it is so rewarding to help others improve their patterns.

Shepherding requires commitment and follow-through by both the shepherd and the author. When you as an author submit a work to a PLoP conference, you implicitly promise to do certain things. Likewise, when you agree to shepherd a paper, you make promises as well. Here is what we expect from both:

The Author:

  • Respond to the Shepherd. The shepherd will be giving you help, free of charge. When you get comments, turn around a new draft of your patterns quickly. You don't have to get it perfect; it is better to be timely than complete.

  • Give two or three Updates. We know you are busy, but just one updated paper right at the end of the shepherding session just doesn't cut it.

  • Attend the Conference. When you submit a paper, you imply that you will attend the conference if your paper is accepted. While we recognize that things do come up, it is your responsibility to arrange funding, visas, etc., in plenty of time for the conference. At this time, no PLoP is asking for a deposit at the beginning of shepherding, but it could happen if people continue to abuse it.

  • Thank the Shepherd. Ok, this is kind of a no-brainer, but it bears repeating. The shepherd is donating time and expertise. The least you can do is thank your shepherd.

The Shepherd:

  • Contact your Author Promptly. Do it right away; the same day you get the paper assigned. It really takes no time at all, and it gets shepherding started on the right foot.

  • Give two or three Iterations of Comments. So plan your time accordingly. You don't have to get everything right; it's better to be prompt than complete.

  • Focus on Substance. This is shepherding, not proofreading.

  • Keep the Program Committee in the Loop. Don't forget to copy your mails to your PC member.

  • Have High Standards. It's ok to demand excellence of the author. At the conclusion of shepherding, you will be asked your assessment of the paper. Don't recommend acceptance just because the author is a nice person, or they really tried. If a paper is accepted, it will be workshopped by as many as ten people. Don't cause them to waste their time on junk.

Shepherds and Sheep:
Rate your Shepherding Experience!

This document represents some guidelines for accepting papers for the PLoP conferences. Any feedback is welcome.

Multiple Paper Submissions

  1. Quick pass read by members of PC to eliminate papers that are in the
    wrong conference or don't pass muster.

  2. Guarantee that at least one author will attend conference -- before
    shepherding -- but how can we back this up?

  3. One author - one paper -- is this too harsh?

  4. Only the author can represent the paper at a workshop, if author can't
    attend, paper is dropped from workshop
