I think that the biggest area for improvement is for their core component, the Java Core Server (JCS). In addition, there could be improvement in the following areas: * Saperion web client: Does not support many rich-client features and is inconsistent between thin and thick clients * The VBA macro API was very poor * No real toolset provided * No debugging options * Workflow engine * No official and supported procedure of deploying/moving a solution between stages, which was officially stated by the vendor
