I wrote this article in Japanese before and translate into English. It is because I think it might be useful for my foreign colleagues to understand Japanese way of deck making process.
1. TO WRITE PREFACE PROPERLY
PREFACE must include background, objective of the project / campaign and definition of challenge to be solved in the deck. PREFACE may play quite a big role for arraigning audiences' minds like brainwashing, moreover justifying the conclusion. In this context, PREFACE might be the essence of the deck. You have to be aware of the importance of writing appropriate PREFACE.
2. TO BUILD MULTIPLE SCRIPTs
SCRIPTs must be prepared at every Merkmals of developing a deck. At the first moment, you should make SCRIPT in text as a story. "20 messages method" might be help for you. Next, based on this story, you should make illustrated SCRIPT like storyboard of TVCM. Making it in small pieces of paper, you could appose those pieces on a desk and reorganize those until you think the story is logical and attractive as if you are solving puzzles. Throughout this process, you could find the missing elements (piece of papers) of the deck and find the way how to make it more and more attractive. After examination of these multiple SCRIPTs, you should make it as an actual deck on your PC.
3. TO SEPARATE MESSAGE AND FACT IN DIFFERENT PAGES
As a interesting technique, FACTs from research, FGIs and benchmarks should be placed on separate pages from your MESSAGEs. Many of you might mix those up, and put MESSAGE on the same page with FACT. Separating MESSAGE from FACT encourages you to think the crucial sentences by yourself like a copywriter. In addition to that, if you have no time to build deck or to talk whole deck in given duration, you could eliminate some FACT pages to save time.
4. TO CONCENTRATE ON WHAT AUDIENCE WANT TO HEAR
The presentation is definitely not the chance "to talk what you want to talk", but "to talk what audience want to hear". So you have to concentrate and check whether your deck could actually be the story that audience want to hear about. In the same context, the orientation is not the chance "to hear what the client want to mention", but "to check your hypothesis on the solution".
