Jede technische Lösung beginnt mit einer Idee, einem Gedanken, einer Skizze, einem Produkt, das irgendwann funktionieren muss. Aber zwischen der Idee und dem fertigen Produkt liegt ein komplexer Prozess. Wenn die Basis für die Wertschöpfungskette nicht eindeutig formuliert ist, können Konstruktion, Fertigung und Prüfung nicht wirklich zusammenwirken.

Die Folge: Nichtfunktionsfähige Bauteile, widersprüchliche Messergebnisse durch vermeintliche Maßhaltigkeit, steigende Kosten durch Nacharbeit und Ausschuss, Konflikte zwischen Vertragsparteien, Missverständnisse zwischen Fertigung und Qualität.

Genau hier setzen wir an: Wir bieten Schulungen und Beratungen, die sich nicht nur an Lehrbüchern orientieren, sondern an Ihren Produkten und Herausforderungen. Wir vermitteln praxisnahe GPS-Regeln (ISO 8015 & ASME Y14.5) für Ihre täglichen Problemstellungen.

Frequently Asked Questions

Frequently Asked Questions (FAQ)

Answers to all key questions regarding licenses, ordering, training & company guidelines

Are there any other payment methods? +

Yes. From an order value of 200 €, you can conveniently pay by invoice via bank transfer. Please contact us at info@gps-practice.com or use our contact form.

How can the “GPS-PRACTICE Expert Hub” be booked for my team? +

The Expert Hub is offered on B2B request with a minimum term of 6 months. Billing is conveniently via company offer and purchase on account (incl. SAP/PO number). After commissioning, we manually activate your team’s company accounts.

How do enterprise licenses work? +

The billing address creates an account using a company email address (e.g. Procurement). Once the team email addresses are submitted via our contact form, user accounts are activated for your team.

The enterprise license is usable without restrictions within your organization (e.g. internal intranet), but external distribution is not permitted.

Are practical examples to be understood as training? +

No! Our platform is intended to help you understand how to apply the tools of geometric tolerancing on real-world examples correctly. Thus, these examples are not to be understood as formal training courses.

Certified in-house trainings and consulting can be booked directly via https://www.gre-tec.de/ or https://www.toleranzen-beratung.de/.

Do I receive additional support to the Step-by-Step Guide? +
