    3. Slide 3 AA 1: Advisory Area “Concepts and Developments”  WG B3.11 - Combining Innovation with Standardisation (Convener: John Finn - UK) Objective: To investigate benefits of innovative (new technologies and arrangements) and conservative (proved standardized designs) approaches and to try to find ways in which the benefits of these two apparently contradictory philosophies can be combined for future, Identification of benefits from innovation and benefits from standardization (questionnaire), Analysis of commonality and conflict between the two philosophies Recommendation on combination of the two philosophies and on methods for dealing with the perceived conflicts. Analysis of the areas of commonality and conflict between the two philosophies Recommend ways in which the benefits of both approaches may be combined and methods for dealing with the perceived conflicts. Disseminate the results through a report and/or papers and through presentation during relevant events Activities: An ELECTRA report has been published in the October 2006 issue.
