Cards are great tools for stimulating ideas and getting over that awful ‘blank sheet of paper’ moment, but once you have worked out a great plan you need to remember it and it may not be convenient to leave all the cards spread out on the table ( you may want them for other plans, anyway). You can quite simply note down the titles and positions on a sheet of paper then you have a permanent record. If you need to share it, a convenient way is to fill the titles in on a spreadsheet, using the cells to follow the card layout. Another useful technique is to just mark each of the cards with a number in pencil, then you can use this as a shorthand to note the cards’ position or to reconstruct your plan.
I’ve also had people in workshops who have built a plan then photographed it either with a camera or on their mobile phone – another useful technique for groups who want to share the same plan.
