Abstract
In this paper, we discuss about relationships between the business performance and the software development methodology. June 2009, I made inquiries about these relationships - introduction of software-development methodology, productivity, awareness, education, etc. - by questionnaires on SW companies in Shizuoka prefecture. As a result, they are aware that importance of productivity, but at least half of companies have no measurement and development methodology, and their productivity depend on skills of each engineer.
