Engineering Tool Chains & Platforms

Popular platforms at a glance

Engineering of sustainable, cutting-edge systems and software is hardly thinkable without a consistent platform and integrated toolchain. Holistic engineering, from the initial idea to the shipped product, is based on a seamless digital interconnection between the engineering disciplines involved, from customer requirements to design and implementation through to testing and ongoing support.

The decision on the most suitable toolchain for a particular scenario depends on your priorities: if agility and ease of use are important, you will probably prefer other tools than for projects where traceability or compliance are crucial. Another criterion is the ability to model systems and software and then simulate execution of those models in order to test them already during development.

Below please find an overview of toolchains offered by leading providers – IBM, Siemens, PTC, and Dassault Systèmes – including a summary of their key capabilities.

IBM Engineering Lifecycle Management (ELM)

IBM ELM is a fully integrated platform for the end-to-end lifecycle engineering and management of complex systems. It covers all phases—from requirements to modeling, testing, and workflows to variant and quality management.
Integration is achieved via the Jazz platform and OSLC, which links information across disciplines and ensures that it remains traceable at all times.

Typical areas of application are safety-critical industries such as automotive, aerospace, defense, and medical technology.

PTC Codebeamer & Windchill

PTC combines Codebeamer (ALM) and Windchill (PLM), two powerful systems for product and compliance-oriented engineering. The platform is aimed at companies with a focus on documentation, variant control, and regulatory requirements. Typical areas of application are medical technology, automotive, rail, and industrial automation, where compliance with standards is crucial.

Siemens Polarion ALM

Polarion is a web-based all-in-one solution for application lifecycle management. It combines requirements, testing, change, and workflow in a single tool and offers interfaces to Teamcenter (PLM) and Simcenter (simulation). The focus is on agility, transparency, and collaboration—ideal for teams that combine traditional and agile methods. Areas of application include industry, mechanical engineering, and automotive, especially in projects of medium complexity.

Dassault Systèmes 3DEXPERIENCE / Cameo

With the 3DEXPERIENCE platform and Cameo Systems Modeler, Dassault offers an integrated environment for model-based systems engineering (MBSE), simulation, and digital product development. Its strength lies in the combination of mechanics, electronics, and software—ideal for holistic, virtual product development. Typical areas of application are aerospace, mechanical engineering, and high-tech systems.
