Gemeindeentwicklung in 7 Tagen is a practical guide for contemporary church community development. Together with the authors, we reimagined how such a book could work—structurally and visually. In a series of workshops, we worked closely with the team to prototype an entire chapter, testing its structure and usability with readers. These insights directly shaped the book's final layout, balancing dense theological content with accessible tools and real-life examples. Although not affiliated with any religious organisation or belief system, we approached this project as an opportunity to translate complex social processes into clear, usable design. The result is a book that invites participation and makes community development tangible within dynamic, real-world contexts.
