The Department’s willingness and ability to systematically record its learning from existing programmes is critical to securing improvements in the future. There have been at least 13 formal reviews of defence procurement policy over the last 35 years, which have provided the Department with opportunities to take stock and learn from experience.41 While existing guidance in the Department is clear on the importance and benefits of recording and sharing learning from experience (LFE), the Department has not systematically gathered and distributed LFE from programmes.42 While most programmes have identified lessons, some have done so more systematically than others. For example, the Warrior armoured vehicle upgrade programme identified that they would have benefited from better collaboration within the programme team, and between themselves and the Ajax armoured vehicle team.
