IVRs need to be flexible. Requirements and services change over time, organizations test and optimize, grow and shrink and the IVR should always have the correct and optimal setup. The best way to achieve that is by making sure the IVR is easy enough to manage so that it can be managed by a person inside the organization. Replacing voice recording, changing menu options or even creating new menus should be a simple task that does not consume a lot of time and does not require long training.
This way the IVR can always be in sync with the latest state of affairs and become a dynamic marketing and service tools to make sure customers get the best experience possible, while the organization doesn’t waste resources.
