Abstract
The best known OO metrics are the suite of six proposed by MIT researc hers. Of these six, three have problems in their definitions, one seri ously (LCOM or lack of cohesion of methods). Here, this suite of metri cs is evaluated from a mathematical point of view and errors in the de finition of CBO (coupling between object classes) and LCOM removed. In addition, a totally new formulation for the concept of 'lack of cohes ion' at the method level is proposed. Illustrative examples are used t hroughout.
