A Case Study of Team Learning Measurements from Groupware Utilization - A Proposal of Measurement Method for the Contribution Ratio of Knowledge

In software development, there is a need to share a variety of knowledge; therefore, team learning (organizational learning) is required. As tools to support team learning, various groupware has been utilized. In groupware utilization, there is variation among development sites, which is suggested to reflect the maturity of team learning. Therefore, a case analysis on a team with a higher maturity of team learning was performed using groupware utilization as a measure of knowledge sharing. The Gini coefficient is used to represent the distribution of assets in economics. An inversion of the Gini coefficient was used to represent the groupware utilization and defined as the contribution ratio of knowledge. When the contribution ratio of knowledge is large, knowledge sharing is considered to be progressing. The contribution ratio of knowledge in this case study was observed to improve in proportion to the duration of the team. In future, we will expand the measurement range and continue to verify the measurement of team learning maturity using the contribution ratio of knowledge. This study measures the state of the team by analyzing their responses to the questionnaire. If this verification is successful, we would be able to measure the progress of team learning using the contribution ratio of knowledge, which can be measured more easily and objectively without resorting to the questionnaire.
