Maybe you have a gut feeling that ECO will make you and your team more focused and more productive, but you have a hard time explaining it to the people that needs to decide? Listen to this presentation to find your arguments! Or have the decision makers listen to it!
The talk goes over both the direct boost effects like generated code from the model, but also covers the dynamic effects that are expected once you are not afraid of changes and you feel completly in control.
