The strengths of the original model (Key areas, Maturity levels, Checkpoints, Improvement suggestions and Stepwise improvement) have been kept and have been made even stronger. The improvements that make the new model truly business-driven are the Clusters and the Enablers.
Since business drivers change over time and from entity to entity, this model is flexible and adaptable, and works in synch with Sogeti’s other worldleading test methodology, TMap NEXT®. But the Business Driven TPI NEXT® model is independent so no matter what test method is used, this approach can be applied under any circumstance.
