Lightning Talk by Takashi Iba, Ph.D. in media and governance, Professor at Faculty of Policy Management, Keio University. at the30th Conference on Pattern Language of Programs (PLoP2023), IL, USA, Oct. 25, 2023 In this talk, I will present the new frontiers in pattern languages of practices. Historically, the concept of pattern languages originated in the 1970s as a design language for "Places" and was later applied to the domain of "Programs." Subsequently, it found applications in areas like education and organizational change, which can be considered as "Practices." In other words, the pattern language has evolved from Places, to Programs, and then to Practices. In the course of the development, we, Iba Lab and CreativeShift, Inc., have developed patterns across various fields within pattern languages of practices, writing over 3,000 patterns in more than 90 areas of practices over the past 20 years. Reflecting on our journey, we have identified five types within what is broadly labeled as "Practices": (1) Profession and Work, (2) Meta-Pattern Language, (3) Everyday Life, (4) Journey of Life, and (5) Forming Society. This talk will particularly focus on the last three types of pattern languages of practices — Everyday Life, Journey of Life, and Forming Society. We will share our own cases and experiences, including a pattern language for a good digital society, which was recently published by the Digital Agency of the Japanese Government.
