It is often also necessary to go through a piloting of the project on a smaller scale, on the one hand to field-test the practical feasibility of the proposed solution, and on the other, to experimentally verify the obtainable benefits. The roadmap must also address issues related to the pilot – issues such as which stores to target, on which classes, tag application modes, pilot processes vs. the roll out process, and so on. Often the pilot represents a project within a project in the sense that the processes may also differ significantly from those of the final draft, and these aspects need to be addressed at this stage.
