I suppose it’s more of the ‘how’ than ‘when’ to integrate and co-develop a new combined company culture. While integration should be carried out swiftly, the way it is carried out seems more important – for example, whether external cultural specialists are required to support the transformation (especially when both sides have vastly different cultural and language differences), whether managers on both sides are culturally sensitive and ready to accept new ideas or ways of working (if not, what courses or workshops should they attend to achieve this), etc.
