PMI國際專案管理學會台灣分會一再強調自己是PMI在台灣唯一合法分會，並且宣佈PMI已正式授權PMI國際專案管理學會台灣分會翻譯中文繁體版PMBOK Guide第四版，預於2009年三月底出版。爲何和PMI官方網站公佈的資料不同?
根據PMI官方網站說法http://www.pmi.org/Resources/Pages/StandardsFAQs.aspxPMBOK Guide第四版只有Arabic、Chinese(Simplified)、German、French、Italian、Japanese、Portuguese(Brazilian)、Russian、Spanish、Korean等10種翻譯版，並無中文繁體版出版計畫。

內容如下
PMI will publish official translations of the PMBOK® Guide—Fourth Edition in Arabic, Simplified Chinese, French, German, Italian, Japanese, Korean, Brazilian Portuguese, Russian and Spanish. Volunteer opportunities on the official translation teams are now closed.
If you wish to translate the PMBOK® Guide into a language other than those listed, please complete and submit the PMI® Permissions Form. A copy of the permissions form can be found on PMI.org under Resources > Publications > Rights and Permissions
