question: The most advanced organizations are decentralized, collaborative and adaptive. This gives them the ability to manage complex situations. Laloux calls these organizations Teal. The aim of this manuscript is to describe the process of implementation of the Teal management model in the Agència de Salut Pública de Barcelona (ASPB). There is a triple opportunity for innovation at the ASPB: political change towards a progressive government, the organisation is in a moment of massive renewal of its staff and there is a generational change that facilitates understanding the Laloux model, and the managers have a technical background with a long history in the organisation, which makes them aware of the organisation's capabilities. The process starts with the involvement of a small group of people (Llavor group) and it is then expanded (Planter group). As well as discussing the bases of the Laloux model, six working groups are formed (How to organise more effective meetings, Physical spaces, Spaces for reflection / trust, Time bank, Annual ASPB staff day, and Space for listening to the voice of ASPB workers) and informative workshops are organised for the whole organisation in which 67 people participated. In total, some 120 people from the organisation have participated in Planter group activities. The success of the first initiatives should help to ensure that the values and principles cultivated go beyond the frontiers of the projects to become a generalised style of management.
