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.

Patterns Resources

Dear PLoP author:

Thank you for taking the first step in making PLoP'05 a contribution to
the patterns community.

Before we proceed to the next step, shepherding, we need to make sure
that as authors you do your part. What will this entail?

First and foremost is your participation in the shepherding process. As
an author, we expect that you will work carefully and diligently with your
shepherd to improve the quality of the content and exposition of your
pattern and/or pattern language. We also expect that for every paper that
is submitted, that at least one author will contribute to the shepherding
of another paper written by someone other than one of their own
coauthors. If you have written a pattern paper that has been workshopped,
at PLoP or another PLoP-like conference, we expect that you will
contribute to the shepherding of another paper by someone other than one
of your coauthors. If you have never shepherded a paper before, don't
worry. A program committee member will help you in the shepherding process.

Second is your participation in the workshop process. Workshopping is
the heart of PLoP. Every paper must be represented by at least one author at
the workshopping sessions at PLoP. To ensure the highest quality and to
allow for reasonable scheduling, an author is only allowed to represent
one or two papers for workshopping. If you are an author of multiple
papers, you have something unique to offer to PLoP. As such, your
contributions to the workshopping of other's work is particularly
valuable. By only representing two papers, others can gain from your
expertise when workshopping their work.

In summary, before we proceed to shepherding, we need a response from
you saying who will represent the paper at PLoP and a statement that the
person who is representing the paper will attend PLoP. As soon as we have
the registration system up and running, we will email you and give you a
deadline as to when you have to register. If you find that you cannot
register by the deadline, you must indicate which of the paper's remaining
authors will represent your paper at PLoP, keeping in mind that no author
may represent more than two papers. If you do not, all shepherding activities
on your paper will cease.

We on the program committee look forward to working with you and your
shepherd in improving your work. We look forward to seeing you at PLoP in

Joel Jones
Program Chair
