ASPICE and CMMI are both process improvement models used to assess and improve software development processes, but they differ in their scope and focus.
ASPICE (Automotive SPICE) is an industry-specific model that focuses on software development for the automotive industry. It covers the entire software development lifecycle, from requirements management to software testing, and provides guidance on best practices for process improvement.
CMMI (Capability Maturity Model Integration), on the other hand, is a general-purpose model that covers a wider range of industries and focuses on software engineering, systems engineering, and hardware development. CMMI has two representations: one for process improvement and another for appraisal, which helps organizations to evaluate their processes against the model's best practices.
Both ASPICE and CMMI are similar in that they provide a framework for process improvement that can help organizations to develop better software products. However, ASPICE is more focused on the automotive industry and provides guidance that is specific to that industry, while CMMI is more general and covers a broader range of industries and disciplines.
