As a ground-breaking service based on the understanding of user behaviour, it aims at optimising or innovating on services and related products. By observing users in their daily thought processes, we realised that they are mainly interested by the end result of the service. This gives the product the key role of an interface used to access this service. The method developed by InProcess mainly consists in a close observation of each sequence of interaction in the customer’s thought processes. These interaction sequences may be private or public areas (my bank or my house), analog or digital products (my furniture or my computer), material or immaterial interfaces (my keyboard or the database in my mobile phone). Then, they are decoded and analysed simultaneously to create the user’s entire thought process. Each problem or shortcoming detected in the user process will thus become an opportunity for innovation that we will transform.
