Häufig gestellte Fragen
What is CAQ software?
CAQ stands for Computer-Aided Quality (computer-supported quality assurance) and refers to software systems that digitally map quality management tasks in industrial production. Such systems plan inspections, record measurement and inspection data, document complaints and support methods such as FMEA, SPC and audits. The goal is to replace paper-based inspection records and isolated point solutions with a consistent, analysable data foundation across the entire product lifecycle. This makes quality data from incoming goods, production and outgoing goods centrally traceable.
What is the difference between CAQ and QMS?
QMS (quality management system) is the umbrella term for all quality-related processes, documents, roles and structures of a company, for example within the framework of ISO 9001. CAQ, by contrast, is the software that digitally supports such a QMS — the technical tool for the conceptual framework. A QMS can in principle be operated without specialised software, whereas CAQ only delivers its value once clearly defined quality processes are in place. In practice, CAQ software above all ensures that the requirements defined in the QMS are consistently recorded, evaluated and evidenced for audits.
Which standards and methods does CAQ software typically cover?
CAQ systems are primarily aligned with the quality management standard ISO 9001 (adopted in Germany as DIN EN ISO 9001), supplemented by industry-specific frameworks such as the automotive standard IATF 16949 with the VDA volumes, the medical device standard ISO 13485, or EN/AS 9100 for aerospace. Methodologically, they support established quality tools such as FMEA for preventive error avoidance, SPC (statistical process control) for ongoing process monitoring, and the 8D methodology for structured complaint handling. Depending on the system, functions such as APQP, control plans, gauge management and supplier evaluation are added. Which of these building blocks are actually needed depends on the industry and the regulatory environment.
How are CAQ and ERP connected?
CAQ and ERP access largely the same master data, which is why the two systems are usually connected via interfaces. The ERP supplies item master data, bills of materials, suppliers and orders, while the CAQ system reports back blocking and release decisions that control goods movements. For example, an incoming goods inspection can make stock available only after a successful release. Some ERP vendors integrate quality functions as a dedicated module, while others connect specialised CAQ solutions via event-driven data exchange.
What does a CAQ system cost?
A flat price cannot be quoted, as the costs depend heavily on module scope, number of users and operating model, and many vendors prepare individual quotations. Module-based licensing is common, with companies acquiring only the functions they actually use, either as a purchased licence or on a subscription basis. On top of the licence fees come implementation costs for installation, configuration, possible custom adaptations and training. Cloud or SaaS offerings lower the initial investment but shift the spending into ongoing operating costs.
Do small companies need a CAQ system?
Whether a CAQ system pays off depends less on sheer company size than on the complexity of the inspection processes and the regulatory requirements. For very small operations with few, simple inspections, spreadsheet-based documentation may be sufficient at first. However, as soon as certifications to ISO 9001 or IATF 16949 are due, several inspection stations need to be coordinated, or seamless traceability is required, an Excel-based solution quickly reaches its limits. In such cases, CAQ software above all eases audit preparation and reduces manual maintenance effort.
What benefits does introducing CAQ software bring?
The central benefit lies in the shift from inspection-based to preventive quality assurance, as deviations become visible earlier through statistical analyses. This can result in lower scrap and rework costs as well as a measurable reduction in quality costs, although the specific effect varies depending on the starting position. A further advantage is the seamless chain of evidence via audit trail and batch traceability, which facilitates internal and external audits and makes it easier to narrow down affected lots in the event of a defect. Industry figures often place the payback period of a CAQ implementation at roughly one to two years, depending on the scope and maturity of the processes.
