First, the author describes Shimizu's operational concept of "Task Environment". And the author presents two problems concerning with Shimizu's concept (1) that Shimizu's concept dosen't give any attention to the relationship of Task Environment and Organizational Structure, (2) that Shimizu's concept dosen't refer to Multi-layered Structure of cognition in the cognitive process of Task Environment The author discusses the two problems on the view point of Simon's Decision-making Theory, Infomation-processing Paradigm, Theory of Information-creation, Theory of duetro learning, Kagono's Epistemology of Organization. Main results are as follows. 1) Members of organization are never concerned with "whole" problem in all its complexity, but always with "parts" of the problem, because of human's cognitive limits of rationality. Distributed part of problem to one menber sets limits to his field of Task Environment 2) There are two type of Information-creation, (1) within the limits of his distributed field of problem, (2) beyond the limits of his one. Innovation based on the Infomation - creation beyond the limits needs bargaining with many other units of its organization, so that it influences the whole structure of decisions in the organization.
