[Note: I read the illustrated manga edition.] I picked this up randomly at my library, curious to see how a notable business book could be translated into manga form. I enjoyed reading it, although as usual with business books, I can't say that everything it covered is applicable to every organization.
I also found it a bit unrealistic how committed all of the executive committee members are to their company -- there's a surprising lack of self-interest among the team, and while it makes sense in the story (since it includes some of the founders), I don't think all organizations are well represented by this level of dedication and sacrifice.
My take-away from this book is the need for organizations to develop a healthy approach to conflict -- neither avoiding it outright, nor letting it develop into personal grudges and verbal assaults. It was quite satisfying to see the fate of a genuinely toxic member of the board... although, again, not necessarily a representation of how these things work out in the real world.
The art style works well, with the exaggerated expressions of the manga style drawings giving a good illustration of the sometimes heated emotions during the characters' discussions.
