The first four levels of the contract management maturity model (CMMM) for buyers bear different names than the first four levels of the CMMM for sellers, but the last two levels of the CMMM for buyers and sellers bear the same names. Does this mean that buyers and sellers do different things in the first four levels of the CMMM and do the same thing in the last two levels of the CMMM? Is it accurate to say the activities of buyers and sellers at each level of the CMMM are actually different but complementary? With each level of the CMMM, do the actions of buyers determine the actions of sellers? In a two-page paper, select two levels of the CMMM, and describe what actions buyers should take in each of those levels and what actions sellers should take in those levels. Additionally, determine whether buyers and sellers are acting in concert in those levels (doing things that are related) or acting independently of each other in those levels. Using the CSU Online Library and the Internet, you must support your answers to the required statements above with facts from a minimum of three sources. Use correct APA formatting when writing your paper, including in-text citations and references.
