Difference in Quality of Test Architecture between Service Providers and Subcontractors

Software testing is designed in various company hierarchy, such as end product/service providers and subcontractors. An end product/service providers generally has a severe responsibility for their software quality, while a subcontractor has a limited responsibility. There can be a hypothesis that there is differences in software quality between service providers and subcontractors. To examine the hypothesis, this research analyzes correlation between quality of test architecture designed by end product/service providers and subcontractors. It is measured by similarity between test architecture documents and software requirement analysis documents using Word2Vec, a language modelling algorithm with neural network. This research showed moderate correlation that subcontractors will design test architecture similar to software requirement documents.
