Abstract
Public Administration Department, NTT DATA CORPORATION has been conducting the Software Process Improvement activities for about four years. In target organizations, a lot of know-how had remained submerged. We experienced a success of SPI activities in a medium-small sized organization when we had been temporarily stationed in its office for problem solving. Since then, we have extracted some useful information from our experiences with the viewpoints of the PMO and the PM of the organization and have disclosed them to other organizations. We call those types of know-how as "Best practices". In this paper, we introduce the result of comparing and evaluating our activities with the SECI (Socialization, Externalization, Combination, Internalization) model.
