The Rational Model describes a logical path to making optimal decisions. Why are there competing theories?

	a.	These other theories outline more details of the deductive reasoning (i.e., logical) process specifically for business decisions.
	b.	While nice in theory, the rational model does not describe the way that people actually make decisions, so more descriptive models were needed.
	c.	The Rational Model doesn't help in routine or tactical situations.
	d.	It not true that people aren't rational and, therefore, they actually do use this model. The other theories only explain very specific decisions.
