In 2015, the Ministry of Defence asked Aleph Insights to help them adopt a more open approach to innovation as a central pillar of the Strategic Defence and Security Review. We worked with 100%Open – the UK’s leading open innovation consultancy – to design a metric that could be used to identify the key enablers and blockers to the initiative’s success, and to collect and analyse data on the indicator using a large-scale survey. The tool (which is now part of 100%Open’s online toolkit) enabled the MOD’s decision-makers to assess the likely impact of proposed interventions and make auditable investment decisions quickly and efficiently.
