Project approach with proaxia

Our proven SAP Activate approach for proaxia Vehicle Sales & Service combines SAP methodology, automotive industry expertise, preconfigured VSS processes and proven project accelerators. The iterative and collaborative approach provides a clear framework from initial scoping through implementation and go-live to continuous operation and optimization.

Together, we establish the strategic foundation for the implementation. The application scope, key business requirements, system landscape and relevant project accelerators are identified to define a clear starting point for the VSS implementation.

Key activities:

  • Definition of the application scope and target direction
  • Identification of relevant processes, integrations and system dependencies
  • Selection of appropriate tools, templates and project accelerators

The project is set up for successful execution. Project organization, responsibilities, implementation approach and planning are aligned, creating a common understanding of the transition, testing, training and go-live approach.

Key outcomes:

  • Project organization, roles and responsibilities
  • Project plan and implementation approach
  • High-level process scope and system landscape
  • Transition, training, testing and go-live planning

Using the SAP Activate Fit-to-Standard approach, VSS standard processes and configurations are validated against the business requirements. Existing VSS interfaces, migration capabilities and other standard solutions are assessed to identify and structure any necessary adaptations.

Key outcomes:

  • Validated process scope across relevant business streams
  • Identification of reports, interfaces, conversions, enhancements and forms
  • Defined adaptation requirements and refined effort estimates

The solution is implemented iteratively based on the results of the Explore phase. Configuration and identified adaptations are developed, while data migration, testing and training progress in parallel. The system and project are prepared for the transition to productive operation.

Key activities:

  • Iterative implementation and validation
  • Data migration, testing and documentation
  • User training and knowledge transfer
  • Preparation of the productive environment and cutover

The solution is transitioned into productive operation in a structured and controlled manner. Final change activities, cutover and go-live are coordinated, followed by focused hypercare to stabilize the solution and support users during the initial operating phase.

Key outcomes:

  • Successful cutover and go-live
  • Stabilized productive solution
  • Transition from implementation to ongoing operations

Following go-live, proaxia supports the reliable operation and continuous improvement of the VSS solution. Application management covers day-to-day support as well as optimization, maintenance and the management of upgrades and releases.
