Many businesses align their business goals and IT strategies to strengthen the validity of business processes. However, the relationships between goals and strategies are often vague. Thus, the level of success derived from their interrelationships may be ambiguous. By coupling GQM+Strategies and SysML, we propose a framework to systematically associate business requirements and system functions. Moreover, we define a profile in Unified Modeling Language (UML), which allows a model to be created by coupling GQM+Strategies and a SysML-requirement diagram.

Temporal logics are widely used in software verification such as model checking. However, creating temporal logics such as linear temporal logics (LTLs) based on property specifications written in a natural language is difficult due to practitioners’ unfamiliarity with property specifications and notations of temporal logics. Although property specification patterns have been introduced to help write correct temporal logics, creating temporal logics using property specification patterns requires an understanding of the pattern system. Since some patterns are difficult to understand, especially for beginners, and the final temporal logics are usually complicated, creating temporal logics using pattern systems is time consuming and error-prone. Here, we introduce a method to create LTLs based on property specification patterns. We experimentally compare the required time and accuracy of our approach to those using property specification patterns. Our approach can improve the creation of LTLs in terms of speed and accuracy. Although our experiment is implemented in Japanese, the results should be applicable to other languages such as English. We also provide a visualization scheme so that practitioners can understand the generated LTLs and confirm that they are correct.
Taketo Tsunoda, Hironori Washizaki, Yosiaki Fukazawa, Sakae Inoue, Yoshiiku Hanai, Masanobu Kanazawa, “Metrics to Predict Future Modifications and Defects Based on Software Requirements Specifications (SRSs),” IEIE Transactions on Smart Processing and Computing, Vol. 8, pp. 1-9, 2019. (invited from TENCON 2018)(Scopus indexed)
In software development, the quality of the upstream process greatly affects the quality of the downstream process. However, few have applied metrics to estimate quality, controlled the quality quantitatively, or verified the relationship between specifications and software quality. One reason is that specifications are described in a natural language, making it difficult to quantitatively evaluate software metrics such as complexity. Although high-quality software requirement specifications (SRSs) lead to successful implementation, neither a simple quantitative evaluation nor an effective indicator to predict modification-prone SRSs exist. Herein the effectiveness of two specification metrics (number of pages and number of previous modifications) to predict future modifications of SRSs and software defects are evaluated. We confirmed that specification quality measured by the specification metrics and software quality measured by the number of defects are related. We also revealed that future modifications are correlated with the size of SRSs.
