ThoughI had worked as a manager for many years. However I still not have systematicstudy of PM relative knowledge, except reading some reference about PMP. LuckilyI got an old book from my company bookcase, and I decided to read through itand note everything I got from this book. On the other hand, it could help mepractice my English. And I am a slower reader, so it would take me a long timeto read through the whole book……lol……
