Incorporating small batches of work is a good agile practice, but it doesn't directly address the issue of making existing workflow impediments visible due to lack of information.

Applying lean manufacturing principles to limit work in progress (WIP) is related to flow, but the direct solution to making "delays or impediments due to lack of information" visible is a Kanban board.
