A roadmap is an excellent tool for combining a set of activities or objectives into the big picture.
The roadmap shows the big goal that is pursued through a set of activities that typically take a period of time to achieve. The roadmap shows how the completion of the different activities ultimately leads to the future state’s big picture.
Creating the activities as a roadmap will also show where the activities do not fit together, or if there are gaps from one activity to the next.
With a solid roadmap, you have confidence you can reach the outcome.
