Abstract
Software-house has two buisiness areas,customized software business and packaged software business.The Customized software business,thought to be stable,fell into a structural recession.Software-house must change its operations to respond to these environmental changes.I chose change to a packaged software business as the study objective of my thesis. My thesis has verification of the hypothesis concerning business heterogeneity. I hypothesized that there is fundamental heterogeneity between the customized software and the packaged soft business of Softwarehouse.I examined that heterogeneity.As well as collaborating the hypothesis by conducting surveys,I abstracted the factors of heterogeneity.
