21st Century security challenges raise questions about the effectiveness of the traditional intelligence learning paradigm suggesting the need of a complex, agile and rapidly changing intelligence analysis approach.In this context, via a holistic learning methodology and a “serious games” solution, the LEILA project will enable to empower intelligence analysts by improving their cognitive capabilities, reasoning skills and creative approach, at individual and group level.The radical innovation of this holistic approach is brought by the combination of several fields which are normally explored and applied separately such as: psycho-sociological and cognitive factors in decision making (e.g. decision biases, critical thinking, multiple reasoning strategies, creativity), decision making strategies under uncertainty (e.g. Bayesian approaches, game theory), and group interaction dynamics in intelligence analysis.A variety of learning experiences (e.g. games of deterrence, intelligence analysis under stress, emergence in highly of collaborative situations) will be elaborated and computerized in different serious games, that will offer the possibility to actively acquire the new IA skills from the different angles.The impact on users’ community will be ensured by partners providing knowledge and learning in the specific domain (NDU, KEMEA, ZANASI), by the early and continuous involvement of end users and stakeholders (partners and their networks), by the iterative design process - alternating pilots and implementation of the learning framework and the serious games - and the intensive dissemination activities.The involvement in the consortium of experienced SMEs in the domains of Serious Games, innovative interfaces, technology enhanced learning, together with important key players and knowledge providers in Intelligence Analysis and in training for law enforcement, will ensure to LEILA the achievement of the defined scientific and technical outcomes.
