I recently ran into an issue with a WPF application that is a continuous operation Kiosk application. The users log in and are presented with a survey. If the Kiosk is ignored for a time period, a timeout occurs and the screen is reset. However, I discovered that when using MVVM light and View Model (context) injection, even though the view is disposed of, the view model is not. This presented itself when a second user was presented the survey after a timeout had occurred, the survey started on page two or wherever the previous user had left off.

Scrum can be a great approach to software development, however the focus of this article will not be on the many benefits of Scrum. Instead, let’s talk about what it takes to get there.

Without trust, scrum can quickly turn into one headache after another.
