Requirements engineering for systems
We transform unclear requirements into precise specifications: structured, comprehensible and validatable. Systematic requirements engineering is the key to success, especially for complex systems .
Are you familiar with these daily challenges in requirements engineering?
Systems rarely fail because of the technology - but because of unclear requirements. There are typical stumbling blocks in every project that can be avoided with the right methodology. We can help you with this.
Unclear requirements
Vague formulations and misunderstandings lead to undesirable developments, costly rework and delays.
Change management
Without structured change management in agile working environments, you quickly lose the overview and cost control when requirements change.
Communication gaps
Information is lost between stakeholders and the development team due to a lack of common language and documentation standards.
Tool selection
Deciding on the right requirements engineering tool that best suits your projects and processes is overwhelming for many teams.
We transform unclear requirements into precise specifications - structured, comprehensible and validatable. Systematic requirements engineering is the key to success, especially for complex systems.
Our requirements engineering process
At ICS, we transform your project requirements through a proven, systematic requirements engineering process - specifically designed for technical and safety-critical systems:
1. survey
We analyze the operational context, record all relevant requirements of your stakeholdersthrough detailed analysis of all input documents and structured interviews - with a special focus on industry-specific and cross-system interfaces.
2. specify requirements
Precise documentation of functional and non-functional system requirements according to established standards. We define system boundaries, take environmental conditions into account and translate vague wishes into measurable, realizable requirements.
3. analysis & prioritization
We analyze requirements for completeness, consistency and technical feasibility. Using model-based techniques such as SysML, use cases or state diagrams, we create a solid basis for viable system architectures.
4. validation & verification
We continuously check whether the correct requirements (validation) have been implemented completely and correctly (verification). In doing so, we ensure complete traceability from the requirement to the test.
5. optimal support
We support you in the selection of suitable requirements engineering tools, create systematic specification templates and develop customized process models - tailored to the complexity of your system.
1. Erhebung
Wir analysieren den betrieblichen Kontext, erfassen durch detaillierte Analyse aller Eingangsdokumente und strukturierte Interviews alle relevanten Anforderungen Ihrer Stakeholder – mit besonderem Fokus auf branchenspezifische und systemübergreifende Schnittstellen.
2. Anforderungen spezifizieren
Präzise Dokumentation funktionaler und nicht-funktionaler Systemanforderungen nach etablierten Standards. Wir definieren Systemgrenzen, berücksichtigen Umgebungsbedingungen und übersetzen vage Wünsche in messbare, umsetzbare Anforderungen.
3. Analyse & Priorisierung
Wir analysieren Anforderungen auf Vollständigkeit, Konsistenz und technische Machbarkeit. Mittels modellbasierter Techniken wie SysML, Anwendungsfällen oder Zustandsdiagrammen schaffen wir eine solide Basis für tragfähige Systemarchitekturen.
4. Validierung & Verifikation
Wir überprüfen kontinuierlich, ob die richtigen Anforderungen (Validierung) vollständig und korrekt implementiert (Verifikation) wurden. Dabei sorgen wir für eine lückenlose Traceability von der Anforderung bis zum Test.
5. Optimal unterstützen
Wir begleiten Sie bei der Auswahl geeigneter Requirements Engineering Tools, erstellen systematische Spezifikationsvorlagen und entwickeln angepasste Vorgehensmodelle – passend zur Komplexität Ihres Systems.

Our requirements engineering expertise
Our certified requirements engineers have many years of experience in complex system projects - particularly in the rail, logistics, energy, IT and automotive sectors.
We combine proven requirements engineering methods with model-based system approaches. For safety-critical applications in particular, we work in accordance with EN 50128 / EN 50716 or related standards and guarantee a complete and traceable engineering process across all system levels.
Effective requirements management for successful projects
Effective requirements management is essential for the successful implementation of technical systems projects. At ICS, we rely on structured processes for requirements elicitation, specification and prioritization - always with an eye on system boundaries, interfaces and system hierarchies. In this way, we ensure that your requirements are precise, feasible and reliable.
FAQ - Frequently asked questions
What is requirements engineering in the context of technical systems?
Requirements engineering (RE) for systems comprises the structured elicitation, analysis, specification, validation and management of requirements for complex technical systems - e.g. in the railroad, automotive or medical technology sectors. The aim is to define all system requirements clearly, completely and comprehensibly.
How does requirements engineering for systems differ from classic RE?
In system-oriented RE, the focus is onaspects such as system context, interface management, traceability and model-based specifications (e.g. SysML). Compared to software projects, RE for systems often requires an interdisciplinary approach and the consideration of physical components.
What role does system architecture play in requirements engineering?
How does ICS ensure comprehensible and valid requirements?
We work with structured requirements elicitation, use standardized templates, carry out reviews and ensure seamless traceability across all system levels. We also validate and verify requirements continuously - from definition to acceptance.
How does ICS deal with changes to requirements?
Changes are a natural part of every project. We rely on transparent change management: changes are documented, analyzed and checked for impact - both functionally and systemically. This allows you to maintain an overview of the project scope and risks at all times.
For which industries is your requirements engineering particularly suitable?
We have special expertise in the railroad, automotive,logistics, energy and ITsectors. Our methodology is used wherever complex systems need to function safely and reliably - in accordance with standards such as EN 50128 / EN50716, ISO 26262 or IEC 62304.
What does requirements engineering by ICS cost?
The costs depend on the scope of the project, industry and specific requirements. In a free initial consultation, we analyze your initial situation and prepare an individual offer - transparent and without hidden costs.
