What an Enterprise Design Partnership actually means.
Large aerospace, defence and energy organisations cannot procure a credit-card subscription, and a single-user licence is not built for their workflow. An Enterprise Design Partnership is an individually scoped engagement — deployment, qualification and integration agreed per programme, not a bigger plan on a price list.
The list below separates what is available today from what is not. Items shown as not currently available are exactly that: they are not shipped, not deployable on request, and cannot be ordered as part of a licence. Where a programme depends on one, it becomes a scoped development item with its own feasibility review and timeline — or the honest answer is that Skalnav is not yet the right tool for that constraint.
REST API access
A limited v1 API is available today under a Design Partner engagement: an organisation token, a ping endpoint and cylinder compute, so your engineers can call Skalnav from Python or MATLAB instead of the browser. It is not a general API covering every calculation, and it carries no API availability commitment. Wider endpoint coverage is scoped per engagement.
Custom KDF curves & norms
A scoped custom-KDF engineering engagement can embed your company’s internal knockdown factors, fabrication-quality classes or in-house reduction factors alongside referenced third-party methods. This is engineering work we agree and deliver per customer, not a self-service feature for arbitrary custom norms.
Company sign-in — OpenID Connect
OpenID Connect sign-in is implemented and tested against a reference identity provider, but it has not yet been run against a commercial directory or accepted by a customer, so we do not offer it as a released feature and will not tell your IT department that it is. SAML and SCIM are not implemented, and OIDC cannot deprovision an account the moment your directory disables it. What is in use today: individual accounts, organisation roles, an audit trail and an organisation-wide MFA policy. If your programme requires federated sign-in, it belongs in the engagement as a scoped item with its own acceptance against your own provider.
Customer-hosted installation
A customer-neutral deployment package, offline signed licensing and operator documentation exist and are tested — including an automated check that the running application opens no outbound connection. What has not happened: any installation in a real customer environment, and any run on a genuinely disconnected machine. So for ITAR, export-controlled, classified or IP-sensitive programmes we will discuss this as a scoped deployment with its own acceptance criteria; we will not sell it as something we can drop into your data centre today.
Technical contact and qualification support
A Design Partner gets a named technical contact and an agreed onboarding package — direct email contact and scheduled review calls, rather than a ticket queue. Support for internal tool-qualification exercises (ECSS-E-ST-40, DO-330) and validation studies against your reference cases is delivered as scoped engineering work. A contractually dedicated support engineer requires a signed support agreement and confirmed staffing, and is not part of the licence.
Uptime SLA
We do not offer a contractual uptime SLA, and we quote no availability percentage, because we have not yet measured and operated against one long enough to stand behind it. Maintenance windows and incident reporting can be agreed in writing; a service-credit-backed availability commitment cannot, until the operational evidence exists.
Procurement-ready paperwork
Formal quotation with VAT-ID, purchase-order workflow, annual framework agreement, NDA, Auftragsverarbeitungsvertrag (DPA under GDPR Art. 28), supplier-qualification questionnaires, export-control declarations. The things large buyers cannot close a deal without.
Value-based agreements
A commercial model tied to a measured outcome rather than seats can be negotiated separately, but only once there is an agreed, measurable baseline and after legal review on both sides. We do not promise a mass reduction or any other guaranteed outcome as a condition of the licence.
Professional (€9,900 / year, excl. VAT) is the right choice for individual structural engineers, small consultancies, and early evaluation inside larger organisations. It covers the full analytical capability, all design bases, unlimited audit-ready reports and the complete standards set, and it permits commercial client work. Team (€29,900 / year) adds the shared organisation for up to five engineers, and Business / Department (€49,900 / year) extends the same scope to about ten. None of them computes differently.
An Enterprise Design Partnership is the right conversation as soon as any of the following apply:
- deployment across a department or programme, beyond ten named users;
- integration into a design-automation pipeline via the limited v1 API;
- formal tool qualification for certification submissions;
- custom KDFs, company-internal reduction factors, or tailored methods;
- a requirement we do not yet meet — SSO/SCIM, on-premise or air-gapped hosting, or a contractual uptime SLA — which would have to be scoped as development work with its own timeline, not ordered as a feature.
→ Talk to us — we’ll scope the right setup honestly, including what we cannot deliver today, and prepare the paperwork your procurement team will ask for. If you would rather see evidence first, a Proof of Value runs Skalnav against one of your real design cases.
