This paper describes how to observe users or systems based on observation engineering method. The observation engineering method consists of observation check points and grasping systems, products and so on. The observation check points were created by observing users, products and systems and so on in HMI. The way of grasping systems, products and so on is to use the association rule and the single case experimental design chosen as good way. Examples using them were shown in the paper.
