Kathleen Cornelis is software architect with Ardatis, one of the leading ICT providers for the public sector in Belgium.

The past two years, she's been involved in Ventouris, a unique, large scale, agile development J2EE project with a team of 30 developers.

She experienced the advantages and challenges of using this methodology for such a large project and helped finetuning and customizing the XP and scrum practices applied.

Since she has practical experience in both RUP and XP projects, she can compare both methodologies and she's strongly convinced of the high value of agile development.
