The invention relates to a device comprising: at least one tool module (4) having a quick-coupling interface (19); at least one support having a quick-coupling interface (19) and designed to hold the at least one tool module; and at least one data processing unit designed for computer-assisted tool management. The support for holding the tool module (4) comprises at least one support frame (16), at least one interface (21) for computer-assisted tool module identification, and at least one sensor unit. The support frame comprises at least one quick-coupling interface (19) for a tool module. The tool module comprises at least one implement (18) for use outdoors, at least one suspension that is compatible with the quick-coupling point on the support frame, at least one computer-readable storage medium (22) for computer-readable data, and at least one interface for transmission of computer-readable data. During the work processes the condition of the tools is detected by means of a pertaining tool management system and stored in a storage medium. Each tool module is unambiguously associated with a storage medium.
