Four practice areas, each available in three package sizes. Choose the engagement depth that matches your project — and scale up as it evolves.
Four practice areas, deep in each
T4Test engages across four complementary domains: hands-on safety & cybersecurity engineering, process-level MBSE & ASPICE consulting, measurement & governance (KPI programmes built on Metrix), and AI in the engineering workflow (Anthropic Claude partner). Each area ships in three engagement sizes — pick the depth that matches the project.
Functional Safety & Cybersecurity
Structured risk analysis, safety/security management, and full lifecycle engineering — compliant with ISO 26262, IEC 61508, IEC 62061 / ISO 13849, ISO/SAE 21434 and the EU Cyber Resilience Act.
Three engagement sizes: Risk Analysis (S) · Safety & Security Management (M) · End-to-End Lifecycle (L).
Discuss a safety engagementMBSE & ASPICE
Process engineering and model-based systems engineering — from structured gap analysis to in-project implementation and ASPICE CL2 support.
Three engagement sizes: Process Gap Analysis (S) · Process Architecting (M) · Implementation & CL2 Support (L).
Discuss a process engagementMeasurement & governance
From “we think it’s going well” to numbers everyone agrees on — KPI programmes engineers trust, Metrix rolled out into Jira / DOORS / Polarion / Codebeamer, review cadences that stay alive after we leave.
Three engagement sizes: KPI Assessment (S) · First Board Live (M) · Measurement Programme (L).
Discuss a measurement engagementAI in the engineering workflow Anthropic Claude Partner
Bring AI into the loop without handing your IP to a chatbot. On-prem vs cloud decided on evidence; review automation with Calix; change-impact intelligence with Semantix — integrated with the tools your team already uses.
Three engagement sizes: AI Readiness Audit (S) · Pilot One Workflow (M) · AI-in-the-Loop Programme (L).
Discuss an AI engagement- Standards covered — ISO 26262 · IEC 61508 · IEC 62061 / ISO 13849 · ISO/SAE 21434 · CRA · Automotive SPICE · ISO 21448 (SOTIF).
- Hybrid engagements — combine areas (e.g. a Safety Management retainer with a KPI programme, or MBSE + AI-in-the-loop). Scoped on request.
- Add-ons — training, coaching, model-based development support, and local-LLM deployment advisory alongside any package.
Every area above can be paired with the PROmeter product family — Metrix for measurement, Calix & Semantix for AI-in-the-loop, Helix for process gates — so the work survives after we leave.
Three engagement sizes, same quality bar
Each practice area ships in Small, Medium and Large packages. The letter indicates scope and commitment, not quality — a Small engagement is still led personally by Dr. Hussain.
S Small — focused assessment
Workshop-led analysis (HARA, TARA, Process Gap). Deliverable: findings report with prioritised recommendations. Ideal for teams in concept phase or preparing for formal assessments.
M Medium — ongoing management
Safety/Security plan authoring and coordination, or process architecting across projects. Interface management with OEMs, suppliers and auditors. Ideal for mid-sized projects with an established team.
L Large — end-to-end partner
Full lifecycle: requirements, design-level analysis (FMEA, FTA, SHARD), V&V support, Safety/Security Case, certification support with TÜV/DQS or ASPICE CL2 assessment preparation. Long-term partnership on series programmes.
- Packages are starting points, not cages — combine areas, split a Large across workstreams, add training on top. Everything is scoped per project.
- Transparent billing — day-rate or milestone-based, your choice. No lock-in.
- Request a package — Safety: S · M · L | MBSE / ASPICE: S · M · L | Measurement: S · M · L | AI workflow: S · M · L.
Who leads it, and what you take away
T4Test is the consulting vehicle of Dr.-Ing. Tanvir Hussain — a TÜV-certified Functional Safety Engineer for both automotive (ISO 26262) and industrial systems (ISO 13849), with 15+ years in safety-, security- and regulated systems development.
What makes the practice different
- Dual depth — equally strong in hands-on technical safety engineering (HARA, FMEA, FTA, SW safety, MBSE) and in management/process consulting (ASPICE, QM, coaching).
- Cross-industry — automotive, aerospace, medical devices, industrial automation. A rare breadth across regulated domains.
- Tool-vendor background — 3+ years at MathWorks developing and consulting on the MATLAB/Simulink safety toolchain.
- Research roots — Fraunhofer IESE, award-winning model-based testing research, part-time lectureship at TU Kaiserslautern.
- TÜV dual-certified — both automotive (ISO 26262) and industrial systems (ISO 13849).
- Independent track record — 6+ years running multiple engagements in parallel at major accounts (Schaeffler, GKN Automotive, Voith HySTech, Manitowoc).
Outcomes you can measure
Certification-ready evidence
Safety Cases, Security Cases and ASPICE evidence files assembled during the engagement — not reconstructed before the audit.
Processes your team actually uses
Process architectures fitted to your tools and team structure, with tool configuration guidelines for Polarion, DOORS, Azure DevOps.
Capability that stays
Coaching built into every engagement so the team can run the process after the consultant leaves. No permanent dependency.
