The AEERO project was led by the University of Wolverhampton and delivered over a three-year period (2016 – 2019) by a transnational consortium of 7 partner organisations from 3 EU member states (UK, Italy and Portugal). These partner organisations included VET developers and providers engaged with industry, commerce and learners to provide training, mentoring and other consultancy services; media specialists and a dedicated technical development partner specialising in interactive and innovative multimedia techniques and technologies. The objective of the AEERO project was to create an innovative, online learning resource that could be used in teaching vocational skills to employees across the EU aerospace sector and its supply chain.The Aerospace sector was a focus due to its importance as a vital high tech and highly skilled industry with huge growth potential and as well as identified skills gaps. These skills gaps included shortages in advanced technology and manufacturing skills as well as shortcomings in advanced manufacturing and lean supply chain management.Based on the project’s research and needs analysis of training requirements for aerospace employers and employees, an app-based training tool focused on Process Mapping; a key Business Improvement Technique that can increase efficiency in any business by identifying waste and non-value-added activity in any individual process; was developed.The AEERO PMAPP App is freely available for download at the Google Play Store. It’s complemented by detailed supporting documents which guide users through the app as well as providing more information on the concept of Business Improvement Techniques, Process Mapping and its importance in Lean Management as well as its role in quality assurance.The project has been widely disseminated to, and tested by, key stakeholders.
