In the management literature, the terminologies of assessment and evaluation in some cases are treated synonymously and are used interchangeably. However, these terms have different meanings and pursue different goals. In the area of ​​public policies, the two approaches to assessment and evaluation have yet to be separated. The article employs discourse analysis to examine the meanings, nature, purposes, methods, and other characteristics of assessment and evaluation in the lexical literature of the educational management (as reference literature) as well as technology management (literature close to the target literature). Accordingly, we have attempted to suggest new definitions, which differentiate between assessment and evaluation approaches in the field of public policy using the results of previous analyzes and metaphorical correspondences, and then define the boundaries of the uses of these tasks in the policy cycle. As a case study, the supportive policies of the Iranian government in supporting knowledge-based companies and institutions have been discussed, and some of the many possible investigations of the functions, outcomes, and practices of these policies listed based on assessment and evaluation. Some examples of challenges due to the inaccuracy in distinguishing between these two tasks and thus performing them incompletely are investigated in this case study and, as a result, deficiencies in the policy cycle and failure of policies to achieve their desired goals have been shown. Finally, the implications of management and policy on how can policymakers act on the paper's ideas as well as the necessity to use them are discussed.

在管理文献中，评估和评估的术语在某些情况下被同义对待并可以互换使用。但是，这些术语具有不同的含义并且追求不同的目标。在公共政策领域，两种评估和评估方法尚未分开。本文采用语篇分析来检查评估和评估的含义，性质，目的，方法和其他特征在教育管理的词汇文献中（作为参考文献）以及技术管理中的文献（接近目标文献的文献）。因此，我们试图提出新的定义，以使用先前的分析和隐喻对应的结果来区分公共政策领域的评估和评估方法，然后定义这些任务在政策周期中的使用范围。作为案例研究，讨论了伊朗政府在支持知识型公司和机构方面的支持政策，并基于评估和评估列出了这些政策的功能，结果和做法的许多可能调查中的一些。评估。在本案例研究中，研究了一些由于无法准确区分这两项任务而导致执行不完全的挑战的例子，结果显示了政策周期中的缺陷和政策未能实现其预期目标。最后，讨论了管理和政策对决策者如何对本文的思想采取行动的含义以及使用这些思想的必要性。
