Open Space Technology World Gathering

October 31 – November 2 in Istanbul – Turkey

Open Space on Open Space (OSonOS) Conferences are gatherings of Open Space Technology practitioners, their clients, curious people, business people, scientists, community activists, and others, all with some interest or experience in Open Space from different places around the world. These events date back to the early 1990’s when they were initiated and hosted by OST originator Harrison Owen, outside Washington DC. In the mid-90’s the annual OSonOS began to move around… Toronto, Monterrey, Chicago. In 2000 it went intercontinental… Germany, Canada (western), Australia, Sweden, India, Canada (eastern), Moscow and Ukraine, Taiwan and, and and… it’s still going. They are all about Open Space and are held entirely in Open Space.

29th WOSonOS  was held in 2023 in Berlin and 30th WOSonOS 2024 will be held this year in Istanbul between Oct 31 and Nov 2. This is going to be the first World Open Space on Open Space Gathering in Turkey ever.

You’ll find here more about Open Space Technology.

In time the Memories end, the remainder is pure Open Space. All the hopes, dreams and plans are gone. All that is left is an empty void of possibility – Open Space. For the first time, in perhaps a very long time, there is nothing on the “To Do” list. For individuals, companies, countries – it is all Possibility.

Open Space Technology (OST) is a dynamic and innovative approach to meeting facilitation and problem solving that enables self-management. Developed by organizational development consultant Harrison Owen in the late 1980s, OST has since been widely recognised and applied in a variety of fields. Based on the need for effective, agile, resilient and participatory ways of working, OST has been adopted in many fields such as business, non-governmental organizations, education, urban planning, public administration, community development and the arts. In a way, the method is the assurance that working methods with the mentioned qualities do not remain on paper due to its structure that offers equal participation to everyone and does not allow any manipulation. In addition, it is a prerequisite for sustainability as it ensures a holistic approach.

World Open Space on Open Space Istanbul offers an important opportunity to experience an “innovative” and “spontaneous” way of working, as well as to exchange ideas and share good practices on issues of global importance.

We believe that Istanbul’s rich cultural heritage and vibrant atmosphere will provide an inspiring backdrop for this meeting and that you will find your time in this beautiful city enjoyable.Come! Together, let’s embark on a journey towards building a better future for all. Your participation will increase the diversity of views and deepen our common understanding.

The venue will be Alan Kadıköy that is a new municipal performance centre that belongs to Kadiköy Municipality. The name of this beautiful performance center is already “Alan” meaning “Space”.

The Kadikoy district (Chalcedon is the first settlement founded by the Greeks of Megara on the Bosphorus in 685 BC) is easily accessible from the venue. Kadıköy and especially Yeldeğirmeni, with many bars, cinemas, restaurants and bookstores, is a residential and commercial district, the liberal cultural center of the Anatolian side of Istanbul. We think that this modern, brand new events center that offers a comfortable and safe space suitable for up to 300 people add a meaning and importance to WOSonOS especially following the loss of Harrison.

We also hope that through this event, we will be able to send a message to Local Authorities about Participatory Approaches. Another characteristic of this neighborhood is that despite the rapidly changing city, there are self organized solidarity movements who are trying to protect their living and green spaces (Valideg Grove). We are planning to invite them to WOSonOS 2024 to enable the event participants feel connected to what is happening locally.
