Delivering fast is also important because it allows you to verify whether your features and bugfixes really are useful. The decision maker behind the creation of an application, who we’ll call the customer, makes hypotheses about which features and bugfixes will be useful to users. However, until they are in the hands of users who vote by choosing to use the software, they remain hypotheses. It is therefore vital to minimize cycle time so that an effective feedback loop can be established.
