16 Best practices organisatie & aanpak Kennis en inrichting van het team - OO kennis is vereist! - Team: PM, Business, Info-Analyst, Architect, Software Designer - Project Management moet het SOA concept begrijpen. Governance & life cycle - Business manager doet service change management! - => eigenaarschap! - Visualiseer de afhankelijkheden! - Introduceer Lead Architecten en Reference Architecture Risico management - Onvolwassenheid van de tools. - Research & Development buiten de projecten!
