"Business Improvement Problem Map: "So, Where Do We Start Changing?" Stalled, Unfinished, and Pointless Improvement Games" Amane Sawatari / Ayana Motoyama Price: ¥1580 #AmaneSawatari #Amane_Sawatari #AyanaMotoyama #Ayana_Motoyama #Book #Society/Management I bought this new as a gift, but it's been sitting unused. I couldn't find any stains as it's unused, but it was opened and kept on a bookshelf, so the storage isn't perfect.
