Difficult to Implement CMM level in Small Companies

Do you think it is difficult to implement CMM level in small software companies?

Small software organizations, and small team projects (such are all students projects at universities) may find it difficult to achieve higher levels of maturity according to the CMM, since many of the key practices suggested by this model are inappropriate to small businesses and projects. Small project teams cannot cope with the overheads produced by the amount of documentation required by the CMM and they must use combined documents to reduce time. In small projects, teams usually have a flat structure, resulting in developers being assigned several roles due to scarce resources.
