A research and development division of a large technology company exists by its project-focuced way of working. Projects are executed in ever changing teams of specialists. Together with others coaches Hans the teams that want to set a positive step in their development. The reasons for asking for coaching differ per case from start-up (as a new team we face a challenging assignment and want to make a good start'), through boost ('our performance is 'ok', but we feel that our collaboration can be improved') to wake-up ('irritation and conflict negatively influence the performance of our team, something needs to be done'). With our Core Skills training we learn participants to balance their attention to Context, Relations and Process next to Content, and guides the team through the different stages of team development. The result is an opener, happier and more effective team, that contributes to a more flexible and agile organisation.
