Description MATURE is investigating knowledge-maturing in organisations. The project is developing individual-level tools for deepening knowledge and organisation-level tools for analysing its effects.The agility of organisations has become the critical success factor for competitiveness and requires that companies and their employees together and mutually dependently learn and develop their competencies efficiently. Failures of organisation-driven approaches to technology-enhanced learning and the success of community-driven approaches in the spirit of Web 2.0 have shown that for that agility we need to leverage the intrinsic motivation of employees to engage in collaborative learning activities, and combine it with a new form of organisational guidance.For that purpose, MATURE conceives individual learning processes to be interlinked (the output of one learning process is input to the other) in a knowledge-maturing process in which knowledge changes in nature. This knowledge can take on the form of classical content in varying degrees of maturity, but also involves tasks and processes or semantic structures. The goal of MATURE is to understand this maturing process better, and to build tools and services to reduce maturing barriers.MATURE’s outcomes will bean empirical analysis of real-world maturing practices, resulting in a sound conceptual model of the knowledge maturing process and ways to overcome barriers to it (particularly including motivational and social factors);a Personal Learning and Maturing Environment (PLME), embedded into the working environment, enabling and encouraging the individual to engage in maturing activities;an Organisational Learning and Maturing Environment (OLME), enabling the organisation to analyse and to take up community activities, to reseed innovation processes and to apply breeding strategies;reusable Maturing Services for seeding and reseeding, and creating awareness of relevant activities.So far the project has developed the knowledge maturing model landscape which is founded on empirical results and is being evaluated in real work practices. A wide set of reusable Maturing Services have also been developed, based on validated Knowledge Maturing Indicators. Further, prototypes have been developed for the following application contexts: a widget-based environment for collaborative knowledge development centred around artefacts (as piloted in the field of labour market information), a semantic social tagging system for sharing knowledge about people (people tagging) and digital resources (social bookmarking) and for the collaborative development of a lightweight ontology, a task management application that connects to business process modelling.
