This paper proposes a logical framework that visualizes worker's system awareness. Generally, this awareness is difficult to compile in a educational book, and is seldom communicated in verbally. To show broad utility of system awareness, we need to show operator's conceptual structure of system operating. We firstly carry out operation analysis of graph drawing task using a spreadsheet software. Based on it, we propose a logical representation of operator's system awareness using Formal Concept Analysis. Using this framework, we analyze the correspondence relations of difference of using functions for each operator and implication from formal concept. As a result, this representation shows the operators' implicit rules which become the selection criteria of system functions.
