Developing a One-Call/One-Click system is an ongoing process, often beginning with one function and adding additional functions over the years. All added functions are connected intentionally to the existing platform and are part of a longer term vision. This vision should be detailed with a timeline, phases, and activities for project management purposes, and updated as new technological developments become available. Functions can connect via the same or different, but compatible, software platforms, so that users interact seamlessly with multiple functions in the One-Call/One-Click system.
The further an organization moves forward in developing a One-Call/One-Click system (e.g., from trip information to booking and payment), the more complex the project will become.
