The planning, coordination, and tracking of projects and collaboration in complex and distributed supply chains has always been an organizational challenge. This also applies to requirements management as one of the first steps in product development. While a few years ago a single system, "DOORS Classic" from IBM, was used throughout the industry, the emergence of similar systems has increased massively in the recent past. Inefficient as well as lengthy and manual processes along the supply chain are also extremely error-prone, resulting, among other things, in non-transparent cooperation.

Cesonia enables efficient and safe sharing and exchange of product requirements and entire specifications thanks to the integration of various requirements management systems and their merging along the supply chain. Throughput processes and real-time coordination help to optimize cooperation between purchasing and development and ultimately external development partners in particular. A web interface allows reading, editing and commenting on individual requirements. A revision-proof audit trail ensures consistent versioning.

Exchange of Requirements with Ceosnia

Cesonia allows processes to be optimized by integrating various requirements management systems and merging them across company boundaries. This applies in particular to the cooperation between purchasing and development and ultimately external development partners. The current process, on the other hand, consists of a large number of manual process steps and is therefore not only extremely error-prone but also inefficient, slow and susceptible to information security gaps. It lacks transparency and traceability.

Cesonia allows fast and comprehensible feedback between departments and companies through the seamless flow of information, continuous workflows and an audit trail that is secure against auditing. This offers great advantages for both the OEM and the supplier, especially in purchasing and engineering.
