Waa maxay MBB? Maxayse u taagan tahay?
Context:McKinsey & Company waa shirkad caalami ah oo latalin maamul ah oo ay aasaastay 1926 macallin ka ah Jaamacadda Chicago James O. McKinsey, oo adeegyo xirfadeed u fidisa shirkadaha, dowladaha, iyo ururada kale. McKinsey waa kan ugu da'da weyn uguna weyn "Saddexda Weyn" ee la-talinta maamulka (MBB), saddexda shirkadood ee ugu waaweyn adduunka ee la-talinta istiraatiijiyadda marka loo eego dakhliga soo gala. Shirkadu waxay inta badan diiradda saartaa dhaqaalaha iyo hawlgallada macaamiishooda.  Hogaanka Marvin Bower, McKinsey wuxuu ku faafay Yurub intii lagu jiray 1940s iyo 1950s. Sanadihii 1960-yadii, Fred Gluck oo ka tirsan shirkadda McKinsey iyo Bruce Henderson oo ka tirsan shirkadda Boston Consulting Group, Bill Bain oo ka tirsan shirkadda Bain & Company, iyo Michael Porter oo ka tirsan Harvard Business School ayaa bedelay dhaqanka shirkadaha. Daabacaadda 1975 ee John L. Neuman ee McKinsey ayaa soo bandhigay dhaqanka ganacsiga ee "falanqaynta qiimaha guud" taas oo gacan ka geysatay isbeddelka hoos u dhaca ee meesha ka saaray shaqooyin badan oo maamulka dhexe ah.
MBB waxaa loola jeedaa "Saddexda Weyn" ee la talinta maamulka. Laga soo bilaabo marinka, ma cadda sida saxda ah ee ay u taagan tahay, laakiin McKinsey waxaa lagu soo daray MBB maadaama ay tahay tan ugu da'da weyn uguna weyn kooxda.
