Model-Based Systems Engineering

People make MBSE successful

Complex technical systems aren't built by tools alone. itemis connects systems engineering, intelligent toolchains, and AI methods into integrated development environments that make complexity manageable.

The starting point

This comes up constantly.

Document-centric development hits its limits

Requirements in DOORS, architecture in Enterprise Architect, tests in separate systems. Traceability becomes unmanageable and every change triggers enormous manual effort.

Fragmented tool landscapes

Teams and disciplines work with isolated tools that don't talk to each other. Data handoffs create redundancy, inconsistencies, and costly rework before every audit.

Evidence chains grow exponentially

Verification and release processes consume capacity that should go into actual development. ASPICE audit preparation takes weeks instead of hours.

Service areas

What we do for you

Requirements engineering

Model system requirements, check them for consistency, and keep them traceable across the entire system lifecycle.

System architecture

Specify, analyse, and validate structures, behaviour, and interfaces of complex technical systems using model-based approaches.

Functional safety & cybersecurity

Integrate FMEA, FTA, FMEDA, and cybersecurity engineering methodically into the development process, per ISO 26262, ISO 21434, and IEC 62443.

Toolchain integration & traceability

Connect heterogeneous tool landscapes, establish continuous data flows, and automate manual handoffs between tools.

Custom tools & DSLs

Develop domain-specific languages and tailored engineering tools where off-the-shelf solutions reach their limits.

Process maturity & quality

Design development processes based on Automotive SPICE and ISO 15288, systematically improve process maturity, and build audit evidence in a structured way.

Our approach

Three pillars, one goal

01

Model-Based Systems Engineering (MBSE)

Model-based development across the entire system lifecycle: from requirements through system architecture, behaviour, and verification to release, using standard (SysML, UML) and proprietary modelling approaches (Mathworks, domain-specific languages).

02

Processes, Methods & Tools (PMT)

Design development processes for regulated industries, build toolchains, and integrate compliance requirements methodically into everyday development, covering ASPICE, ISO 26262, ISO 21434, and IEC 62443.

03

AI-powered engineering support

Apply AI purposefully for requirements engineering, traceability, compliance evidence, and impact analyses. Human-in-the-loop remains a core element of safety-critical development.
