Case Study (3/4): Adequate Tool SupportVector Agile Solutions

Based on “effect chain analysis” the related tasks for safety analysis update can be identified (e.g. are safety related operations affected by change)

Tooling is mandatory for efficient and consistent change handling.

PREEvision provides here complete consistency

Scenario: Perceived “small change” leads to negative impact on safety and security

Challenge: Continuous impact analysis and consistency

Approach: “Continuous” Safety Case

Architecture + Design

Lessons Learned and Look Ahead: Agile Scaling is Necessary – Yet not EasyVector Agile Solutions

Agile must be tailored and scaled according to the specific environment

Heavy recipe-style frameworks do not address automotive needs

With optimized agile tailoring the overall efficiency will increase significantly

Managing change for organization and culture is biggest challenge

Business Organization

Technology Process

50% of agile transformations fail.
