OnlineAnytime Package

Time (or lack of it) is always a problem in the day to day running of any team. As a consequence, training can be pushed aside. To make fulfilling your training requirements easier, we have developed a large portfolio of OnlineAnytime courses which can be completed at any time and in any location. Even a globally dispersed team can log on to our academy, find suitable courses and complete an agreed training programme at their own convenience.
