Business Considerations

Why do we need the feature? What plans do we have with that feature

Goal: Agree objectives between business stakeholders (e.g. marketing, x-Carline Planning)

Feature from a customer perspective

Translating customer wants and market needs to stable, consistent and complete feature requirements

Goal: Requirements agreed between all stakeholders

Depending Business Model• Relate SW specification details to external impacts,

e.g. SW, HW and Systems suppliers

Logical functions necessary to implement the features

Translating customer requirements to implementation independent engineering requirements.

Goal: Enable efficient reuse of specifications across ECUs and car lines (Core)

Allocated logical functions (platform / ECU) • Technical interfaces of components are determined• Component behavior is enhanced/refined by technical requirements

Goal: • Consistency of x-ECU interfaces enable interoperability • Efficient data exchange with supplier

Current challenges SW development is often disconnected from other engineering and

management activities System-level concepts such as dependencies, architecture and safety/security

are not systematically considered and tested In our recent Code Quality Assessments at customers we didn’t see one single

sufficient architecture description Over 30% unnecessary cost for rework due to changes

Vector ACE and PREEvision Agile for Critical Engineering brings agile to automotive E/E ASPICE Management and Supporting processes benefit from agile ASPICE Engineering processes benefit from integrated tools Document driven development will be replaced by model-driven reporting

methods PREEvision offers all the needed functionality and methodology

Conclusion and OutlookWhere Do We Go From Here?

Agile systems engineering needs Vector PREEvision and method support24/27


Markets appreciate the Vector value PREEvision has become the industry reference

standards for architecture development, used by Daimler, John Deere etc.

Vector supports agile introduction of PREEvision, e.g., Daimler, Ford, John Deere, Renault

Vector consulting brings the necessary method support

Tangible business value Self-organization reduces effort significantly

compared to classic project management Less cost and rework due to managed complexity Better predictability due to transparency Improved design speed with quality and reuse.

Component Supplier:

“I simply open the Kanban Board of the Scrum of Scrums. If I see no progress after 3 days, I know the team has a

problem. But I do not see this often.”

OEM:

“Collaboration effort has been reduced by over 20% with agile systems

engineering.”

OEM, 2 weeks after start:

“Now we see progress.”
