Can Use Cases Really be Used in an Agile Environment?

Webinar – Recorded | Oct. 17, 2013

Along the way, managers and team members have lost sight of Agile's principles and tried to enforce the use of certain tools and structure where they may not belong. In this one hour webinar, Perry McLeod will explain how tools such as use cases can be successful in an agile environment, provided the principles of agile are always active in the minds of the managers and the team members that are using them.
