Problem (multiple clients)
- Migration or replacement of a large system confronts clients with big challenges because of the sheer size and complexity, and managers have little experience of such projects
- As the systems are critical to business, the conversions simply have to work, serious problems or even failure are not acceptable
- The systems are extremely complex, some of the interfaces and functions have been forgotten, some managers are no longer available
Contribution of ResultONE
- Development of an effective overall approach to the conversion
- Creation of transparency concerning the interfaces involved and collaboration with partner systems, resolution of target system uncertainties (for large function blocks, the target system is usually defined; with small functions, the need for migration/integration and transfer to the target systems is often unclear, however)
- Completion of a migration study, development of migration plans with the aim of avoiding a big bang conversion and implementing gradual migrations with fallback options, detailed development of the quality gates for approval of the next steps
- Setup of the necessary project structures, support for internal project managers in delivering the project, coordination with relevant departments and provision of a decision-making mechanism in the form of steering committees
Outcome
- Clean technical migration, transparent involvement of the departments concerned and support form the management made a significant contribution to the smooth conversion
