Clearly, Clark is referring to effectiveness as the degree of success experienced by institutions performing marketing functions while efficiency is concerned with the minimizing of the costs of performing marketing functions. Although Clark did not explicitly express the two concepts of effectiveness and efficiency of performing marketing functions in the context of an output/input, this concept was implicit in his seminal article on the subject. The output of the marketing system is the work (marketing functions) undertaken by marketing institutions. The input is the costs associated with performing the marketing functions. If the output were to remai constant while costs were decreasing, the work of marketing would be more efficient. Or, if the output decreases even if costs remained constant, efficiency would decrease.

显然，克拉克所指的作为经验丰富的营销职能虽然效率与执行营销职能的成本最小化有关的机构的成功程度的有效性。虽然克拉克没有明确表示这两个概念和效率的营销职能中的输出/输入上下文，这一概念是有效性的隐含在他开创性的文章，关于这个问题的。市场营销系统的输出是 (市场营销职能) 进行营销机构的工作。输入是与执行营销职能相关的费用。假如输出到苦果常数而成本均呈下降趋势，市场营销的工作会更有效率。或者，如果输出减少即使成本保持不变，效率会降低。

很显然，克拉克指的是机构在执行营销职能时所经历的成功的程度，而效率则是关于履行营销职能的成本最小化的问题。虽然克拉克并没有明确表达的概念的有效性和效率的营销功能的背景下，一个输出/输入，这一概念在他的开创性文章中是隐含的。营销系统的输出是营销机构承担的工作（营销职能）。输入是与执行营销功能相关的成本。如果输出是保持不变而成本降低，市场营销工作将更有效。或者，如果输出减小，即使成本保持不变，效率会降低。
