Potential Blockers for Improvement

• Unclear goals for those performing the process

• Varying sense of urgency within the organisation

• ”No time to change now”

• ”No time or will to share experiences”

• Defining process is somebody elses problem

• Lack of management committment

• Resistance to change

Automotive Grade SW is more than its function

• has a low fault density• is safe• is buildable• is possible to simulate and has one or more model representations• is testable• is maintainable• is ”documented” or described in some form that makes it possible to

understand • is secure• is dependable• is fit for purpose and has the functionality that the customers expect
