When a single planning session spreads across two or three separate boards, it usually means one larger, continuous surface would serve the same purpose better. Splitting a workflow this way also makes handovers slower, since whoever picks up the work has to piece it together from several boards. It also makes it harder for anyone joining partway through a project to follow the full picture, since no single surface holds the complete context. A modular whiteboard wall solves this specific problem without losing the continuous, joint-free feel of one board, which matters when the workflow itself depends on treating the surface as a single space.
Before assuming the only fix is adding more boards, it is worth checking whether Chameleon’s maximum single-panel size, 1180 by 2980 millimetres, would cover the combined workflow on one continuous surface instead, which is often more usable than several separate boards.
