Online maintenance: return for reparation for the more recent products (sep-top boxes, cell phones…) is close to 20% while it is close to 5% for mature (i.e., enough tested) products (paper on the Novo company, Nouvel Observateur French magazine, 2004) User practice spying: marketing studies, ergonomics improvement, others… Development of business QoS policies such as ?
