TDD and System Architecture

Net Objectives

In truth, some of these problems actually indicate faults in the system architecture. For example, developers will struggle to write unit tests of behavior that is embedded in a user interface, or in stored procedures … Continue reading "TDD and System Architecture". When first adopting TDD, developers can run into some roadblocks that seem to indicate that TDD is a difficult process.

How we do Agile - principle-led & context-dependent

Marcusoft

The teams are responsible for products or a value stream (for example Partner Portal or Internal administration systems). This is why we have created autonomous teams that can govern themselves and quickly make decisions, change their minds and find better ways to improve their value stream/product/systems to reach the effect. And another, equally big problem is that our systems are built, over many years, to support the functions and not the flow of value. Agile is soon (?)
