YOUR CHALLENGES

Wherever you are in the engineering lifecycle, we bring depth to each domain.

We start from your program, your standards and how your teams actually work, before we talk about tools. Pick the challenge closest to yours.

Pass audits and certification

Produce ISO 26262, DO-178C and ASPICE evidence without rebuilding it by hand.

Learn more

Close traceability gaps across tools

Keep requirements, models, code and tests linked when every team uses a different tool.

Learn more

Adopt and scale MBSE

We help teams move from documents to models, and make the models the source of truth.

Learn more

Move models between modeling tools

Convert Rhapsody, Sparx EA and System Architect models to Cameo, and back, without redrawing.

Learn more

Run formal reviews across every tool

Review, approve and sign off requirements from one place, with an audit trail.

Learn more

Generate certifiable embedded code

Use UML on targets with tight memory and CPU budgets, including AUTOSAR Classic.

Learn more

Deploy, upgrade and host IBM ELM

Get IBM ELM running, current and adopted, on-prem or hybrid.

WHAT WE COVER

Six engineering disciplines. One connected thread.

Every engagement draws on the disciplines your program needs, so process, tools and data are never solved in isolation.

requirements-traceability
Requirements engineering & traceability

Capture, review and validate requirements in DOORS, DOORS Next or TopTeam, and trace them through design, code and test.

mbse-software-engineering
Model-based systems & software engineering

Build SysML and UML architectures in IBM Rhapsody, Cameo or Sparx EA, and keep models in sync across tools with no manual re-translation.

certifiable-code
Embedded software engineering

Generate production code from UML for constrained targets, with certification-ready frameworks for safety-critical and AUTOSAR software.

testing-qa
Testing & quality assurance

Plan, run and trace verification in IBM Engineering Test Management, linked to the requirements it proves. 

audits-certification
Safety & certification

Cut the effort to demonstrate compliance with ISO 26262, DO-178C, IEC 61508 and ASPICE, with evidence generated from the toolchain itself.

linked-data-oslc
Linked data & OSLC integration

Connect ALM, PLM and developer tools through the OSLC standard: live links, no copies, no sync lag. 

OUR APPROACH

Three pillars of audit-ready engineering: Process + Platform + Connected data

A well-configured DOORS Next instance does not pass an audit on its own. Traceability holds when the process is modeled correctly, the platform fits how engineers work, and the data flows across every tool in the program. That is why every SodiusWillert engagement is built on three complementary pillars.

Process expertise (Implement)

Workflow analysis, standards mapping, tool selection, MBSE and requirements coaching.

Learn more

Platform mastery (Extend)

Technology deployment, hosting, upgrades, training, support, and purpose-built extensions for Rhapsody and DOORS Next.

Learn more

Connected data (Connect)

OSLC Connect, Publisher, ReqXChanger and SECollab: our own technology, linking requirements, models and tests across your toolchain.

HOW WE WORK WITH YOU

We stay with you across the full tool lifecycle.

SodiusWillert is an IBM ELM Platinum Partner and engineering process consultancy. We help teams in regulated industries (e.g. aerospace, defense, automotive, medical, and railway) select and master the tools that fit their environment, then extend and connect those tools to the broader engineering ecosystem so traceability holds up under audit and certification moves faster.

Evaluate & Select

We help analyze how your teams actually work today: where traceability breaks, where compliance evidence gets rebuilt by hand, where a tool is fighting your process instead of supporting it. From there, we help you select the platform that fits your standards, your team's maturity, and your certification requirements.

Deploy & Grow

We stay through configuration, rollout, and training running workshops, coaching engineers through the transition, and adjusting the plan as real usage reveals what it missed until the tool is part of how your team works, not a system they route around.

Extend & Optimize

Base tools rarely cover everything a regulated program needs, and we don't ask you to work around the gaps. We build purpose-built extensions, keep your environment running with ongoing maintenance and support, so your team can focus on engineering.

Integrate & Scale

Traceability gaps are never any single tool issue, it's that your tools don't talk to each other, so traceability gets rebuilt by hand every time something changes. This is where our own technology comes in: OSLC connectors, Publisher, ReqXChanger, and SECollab connect your toolchain end to end, so requirements, models, and tests stay linked as your program scales.
