THE CHALLENGE

Ambition up, velocity under pressure.

The challenge is not adopting technology. It is managing the complexity that comes with it. Integration effort, delivery risk, and lifecycle cost are now rising faster than teams can absorb them.

Complexity is rising faster than productivity

Adding engineering capacity alone will not close the execution gap.

Foundational integration consumes substantial effort

The work is mandatory, but repeating it for every program is a choice.

Delays and recalls remain common

Symptoms of the operating model, not just the pace of feature delivery.

The Work Required of OEMs

The missing layer represents real work

Without an automotive software foundation, the layers between the RTOS and the OEM platform still have to be delivered, and that work shifts into the vehicle program.

  • Integration Tax: The recurring, non-differentiating work of turning proven components into one dependable, production-ready execution environment.
  • Repeat Tax: The portion of the integration tax repeated across ECUs, SoCs, domains, safety profiles, supplier releases, and vehicle programs.
  • System-Level Proof: Components can be proven individually. The OEM must still prove the assembled system.

THE ANSWER

What OEMs need: a foundation integrated once and reused many times.

The developers building these systems are clear about where their time goes, and where they want it to go instead.

60%
say foundational integration consumes 25%+ of total development effort
69%
build or integrate their own foundational software
76%→9%
say OEMs should focus on the application layer, yet only 9% do
34%
say a pre-integrated foundational platform is the answer
75%
say the lack of a common, reusable foundation slows SDV development
