The TIMETOACT GROUP provided ZF with comprehensive support throughout the entire certification process.

ZF receives ISO/IEC 5230 certification
ZF receives ISO/IEC 5230 certification for open source compliance in record time
The challenges in maintaining and managing open source compliance are manifold. In order to ensure the correct handling of open source, ZF Friedrichshafen AG decided to have the compliance of its open source software officially certified according to ISO/IEC 5230. TIMETOACT GROUP provided comprehensive support to ZF throughout the certification process. This included conducting a maturity analysis, addressing gaps identified by the TIMETOACT Software & Consulting team, and facilitating the audit and certification by ARS (Audit and Risk Solutions GmbH). ZF benefits from a minimisation of risk and the positive image of the certification in the industry.
ZF strives for ISO/IEC 5230 certification
Software development is becoming increasingly important for ZF Friedrichshafen AG, a technology group based at the Lake of Constance - and with it the topic of open source. But there are many obligations and requirements for the use of open source in order to ensure compliance. Following ZF‘s focus on establishing the OSPO (Open Source Programme Office) over the past two years, the second step was to achieve ISO/IEC 5230 certification. The main aim is to create trust in the supply chain and improve internal processes.
ISO/IEC/IEC 5230 certification is an international standard of OpenChain for the most important requirements of a high-quality open source licence compliance program. These include licence compliance processes, roles and responsibilities and process sustainability.

„We already know TIMETOACT from numerous projects. After they had already supported us in setting up our OSPO, it was only logical that they would also accompany us through the certification process. The collaboration was just as we knew it: constructive and on an equal footing with fast and uncomplicated communication“
TIMETOACT supports and advises ZF in the preparation process
The certification comprises a three-stage process. OpenChain itself was always available as a professional contact partner and provided support during the certification process.
Step 1: Maturity level analysis
In 2023, the project began with a comprehensive maturity analysis. This initial phase aimed to assess the current status of open source compliance within ZF and to gain an overview of the readiness for ISO/IEC 5230 certification. To address this objective, TIMETOACT has devised a maturity model based on ISO/IEC 5230, leveraging it to assess adherence to standard requirements. The maturity level is tested through various audit techniques, such as interviews, process analyses, and document review.
In the maturity analysis, the TIMETOACT project team proactively identified potential enhancements to individual interview partners, facilitating their efficient and seamless implementation.
Step 2: Gap analysis and gap closing
The maturity analysis was followed by the gap analysis, in which TIMETOACT identified specific gaps and potential for improvement. It was particularly important for ZF to ensure that all aspects of open source management match with international standards in order to achieve the certification. The gap analysis revealed that some internal processes and guidelines needed to be further developed to fully fulfil the requirements of ISO/IEC 5230. These gaps were successfully closed by the TIMETOACT project team.
Final audit and certification by ARS as external auditor
The TIMETOACT GROUP, to which ARS (Audit and Risk Solutions GmbH) belongs, has undertaken an extensive certification procedure. ARS have assumed responsibility for conducting the audit and certification, as per compliance regulations which mandate the separation of certification and consulting functions across distinct entities.
Step 3: Audit and ISO/IEC certification
The audit procedures were conducted in accordance with internationally recognized standards by ARS and included both document review and interviews with relevant team members. ISO/IEC 5230 certification was achieved in April 2024 and represents a significant milestone for ZF in the area of open source compliance.
To ensure continuous compliance with the ISO/IEC 5230 standards, the audit is carried out comprehensively every three years. Between these audits, annual surveillance audits take place to ensure that ZF continuously fulfils the certification requirements. These regular reviews are critical to maintaining the compliance and quality of ZF‘s open source software practices.

„As a certification instance, our focus is on ensuring that the ISO/IEC 5230 standards are applied correctly and comprehensively. In our role as auditors at ZF, we have seen an impressive commitment to compliance and quality. This certification is a clear sign of the seriousness with which ZF takes its responsibility in relation to open source software“
ISO/IEC 5230 certification brings transparency and compliance
Thanks to the partnership with TIMETOACT and with the support of ARS, ZF was able to achieve a high level of maturity in dealing with open source compliance and fulfil the ISO/IEC 5230 standard. In less than a year and a half, ZF with over 160,000 employees was able to achieve the certification. This not only strengthened their position in the market, but also increased internal efficiency and awareness of the importance of open source compliance.
ZF benefits from the following advantages with ISO/IEC 5230 certification:
ZF has not only fulfilled the basic requirements of ISO/IEC 5230 but has even gone beyond them. With 90% of the maturity indicator, ZF is above the target of 80%.
The ZF team is not only well trained, but also active in the implementation of compliance measures.
There is a strong understanding of the importance of compliance throughout the organisation, which is important for the long-term and responsible use of open source software.
ZF demonstrates its commitment to open source software by establishing and supporting a dedicated office for open source program.
ZF has developed effective processes and clear documentation that can be considered best practice in the area of open source compliance.

„ISO/IEC 5230 certification is a milestone for any organisation that is serious about using open source software. We are excited to see how ZF, working with TIMETOACT and ARS, is not only meeting compliance requirements, but also setting best practices for the entire industry. This underscores the importance of the OpenChain standards as the foundation for reliable and transparent open source governance“
Manager Open Chain Project Added value through compliance with ISO/IEC 5230
ISO 5230 certification can offer various added values for a company:
Adherence to ISO 5230 standards allows companies to standardize and optimize their processes, ultimately resulting in improved product or service quality.
ISO certification is internationally recognized and can help improve the quality of the company.
Companies that are ISO 5230 certified can positively differentiate themselves from competitors as it shows that they are committed to maintaining high quality standards.
By implementing the requirements of ISO 5230, a company can increase its operational efficiency by eliminating redundant processes and streamlining operations.
ISO certification helps companies mitigate risks related to product quality and compliance, as it helps identify and reduce sources of error.
By improving processes and reducing errors, ISO 5230 certification can help reduce costs in the business, whether through reduced waste, lower rework, or improved resource utilization.
ISO certification signals to customers that the company is committed to the quality of its products or services, which can increase customer trust and can lead to long-term customer relationships.
ZF will continue to work with the experts from TIMETOACT Software & Consulting and ARS in the future. The ongoing closure of identified gaps and regular monitoring audits ensure that ZF‘s high compliance standards are maintained.

„Many thanks to OpenChain for their support and the great collaboration with ZF. It was a pleasure for us to work with companies that are so committed to excellence and quality - we were able to achieve our goal in such a short time“
