Director, Castle Consulting Ltd.

Mike Pluke is founder and lead expert of Castle Consulting Ltd. an ICT user experience company. Prior to founding Castle Consulting Ltd., Mike was a manager in BT's Human Factors Division. Mike's last long-term BT role was managing user experience standards activity both internally within BT and also in European and international standards fora.

Mike has recently helped ETSI's Human Factors committee identify new areas where user experience standardization activity is required. A principal theme of Mike's work has been identifying how people can exercise greater control over the ways that they access information and communicate. He identified major weaknesses in the ways in which people can currently identify themselves in information and communication environments. To resolve these weaknesses, Mike proposed a Universal Communications Identifier (UCI).

Whilst developing the UCI concept, a number of other areas such as user profile management and personalizing the user experience to a person's language and cultural needs emerged. Mike continues to help ETSI to develop these important new areas.

Mike has edited many ETSI standards and guides and is currently working in ETSI Specialist Task Force STF302 to identify how UCI can be most effectively incorporated into future NGN solutions.
