Fig. 2). The CAD files they produce are kept in a database that is called Product Data Management (PDM) system. Designing components often takes many months, considering adaptations required to accommodate changes in other components, so it is an on-going activity. Packaging is carried

out by the packaging team, which consists of 20 employees who do nothing other than packaging. Once a packaging activity is triggered, they transfer the files that correspond to the components they are checking to another computer system (and file format) and use a Digital Mock-Up (DMU) virtual simulation software to run calculations that simulate interaction between the components to evaluate the effects in the various dimensions (ergonomy, etc.). All the performances listed above (manufacturability, space limits, etc.) produce a list of anomalies that specifies all instances in which the requirements were not met.3 One member of the packaging team then filters this list for anomalies that do not create practical problems or whose cause has already been eliminated, and all the heads of the different engineering units (engine, interiors, etc.) then meet to discuss the remaining anomalies. The anomalies list allows the packaging team and the engineers who are the ‘owners’ of the problem (i.e., the component that exhibits anomalies) to coordinate their efforts. The anomalies are also registered in the log-book, the official document used by the development platform to keep track of the project’s evolution, record and monitor the resolution of the anomalies as well as the technical solutions adopted, and enable team members to discuss potential modifications of the project’s objectives with the client. The packaging activity follows a cycle with a regular rhythm, described in the written procedures that prescribe fortnightly cycles of checks for most components (some follow weekly cycles, but the object we follow in this paper was subjected to bi-weekly cycles) (Fig. 3).
3.4. Recurrent interaction patterns in packaging
In this section, we first describe how the task is supposed to be carried out according to the
procedures and norms and, subsequently, how it is carried out in practice. The description below follows the nine-step structure of packaging as described in the procedures.
3.4.1. Step #1: Releasing the CAD files for use by the packaging team
