Automotive Spice, or ASPICE, stands for Automotive Software Process Improvement and Capability Determination. It was created to assess the performance of the development processes of OEM suppliers in the automotive industry.
ASPICE was developed within the ISO/IEC 15504 standard - Software Process Improvement and Capability Determination, also known as SPICE. Where SPICE gives the framework for software process assessment, ASPICE applies this framework to the automotive industry. Together with functional safety standards (ISO 26262), Automotive Spice provides effective safety practices for the sector.
What is ASPICE in Automotive?
When you think about a car these days, what comes to mind is a smart vehicle: a big display with a touch screen and apps, fully integrated with your smartphone. On top of that: video rear-view mirrors, wireless charging docks, adapted cruise control and auto-park features, or even stolen vehicle tracking software.
Advanced technology only encourages further product innovation within the automotive industry. Considering the plans for cars to be even smarter with augmented reality head-up display, enhanced gesture control and enabling communication between vehicles, there is no surprise that 80% of car manufacturers focus on software development. Integrating multiple technologies is slowly turning cars into computers on wheels, which means they not only are liable to small oil leaks but also software malfunctions or potential cyberattacks.
What does ASPICE mean for OEMs and suppliers?
ASPICE framework is a widely recognised standard, and key worldwide brands like BMW, Ford, or Audi use it to evaluate their electronic and software suppliers. It gives more control over the development process and mitigates issues coming from the quality assessment level. Therefore, for suppliers who are thinking about working with big OEMs, ASPICE certification is a must-have. ASPICE simply assures seamless cooperation between Original Equipment Manufacturers and suppliers by defining the system development process and improving the overall process capability.
ASPICE certification has a 5-tier scale which determines the project maturity level:
Level 0 – Incomplete: – ASPICE requirements are partially met, and some process improvements are required to meet higher standards
Level 1 – Performed: Standard requirements are closely met, but some areas in the process need improvement.
Level 2 – Managed: ASPICE standards are nearly or entirely achieved, and reliable product delivery is in place.
Level 3 – Established: Performance and industry standards are being established and unceasingly developed and improved.
Level 4 – Predictable and Level 5 – Innovating: Established standards and continuous progress measurement, analysis, and evaluation lead to constant innovation.
ASPICE Verification and Validation model
The verification and Validation model, also known as V-model, is what Automotive SPICE builds on. This model is strict in its requirement for constant evaluation and development. This way, potential issues can be eliminated at the first stage, and improvements can be applied accordingly.
V-model is divided into two stages. Each one of them has different phases:
The initial stage includes:
- Requirement Analysis
- System Design
- Architecture Design
- Module Design
The secondary stage includes:
- Unit Testing
- Integration Testing
- System Testing
- Acceptance Testing
We like our cars to be smart, to keep us safe on the road and to make the driving experience nice and easy. What we don’t think about is the technology that is behind all of this. Each year major car dealers add something to the list above to make their vehicles even more exciting and attractive to a potential buyer. And this is where the ASPICE frameworks come in, ensuring that safety standards are met, potential challenges moderated, and the software development process goes smoothly, bringing satisfactory results.
