RecommendationsRecommendations
Step by step approach Complex and time consuming Parallel data maintenance for long time Customers have time to convert their
systems Employees‘ skills can be developed and
experiences may influence new components
IT Renewal Strategy Europe
RecommendationsRecommendations
Big bang approach Easier to implement Long development and test phase Short migration period Customers have to be involved Education program parallel to normal
work process New work flow needs new skills

ConclusionConclusion
Strategy has to fit in the situation in each individual country
All strategies have strengths and weaknesses
No cookbook, just good practice guidelines
