The integration of new technologies at the scene of crime is often seen by managers as providential: more traces of higher quality will be collected in less time, without increasing human resources. It generally takes the form of devices of different shape, size and weight that help to recover and collect traces, as well as to remotely interrogate databases. However, each tool can also reduce mobility, necessitate specific knowledge and be used in hostile conditions (humid, dirty, cold…); the simultaneous use of several devices amplifies these difficulties. Thus, in order to successfully employ latest technologies, it is suggested that the traditional Business Process Re-engineering practice should:
– provide a global perspective that take into account pragmatic constraints, rather than focus on individual tool,
– use the concept of wearable computer as a framework for further developments.
