Conference Object Citation - WoS: 4Complexity Metrics for Cascading Style Sheets(Springer-verlag Berlin, 2012) Adewumi, Adewole; Misra, Sanjay; Ikhu-Omoregbe, NicholasWeb applications are becoming important for small and large companies since they are integrated with their business strategies. Cascading Style Sheets (CSS) however are an integral part of contemporary Web applications that are perceived as complex by users and this result in hampering its widespread adoption. The factors responsible for CSS complexity include size, variety in its rule block structures, rule block reuse, cohesion and attribute definition in rule blocks. In this paper, we have proposed relevant metric for each of the complexity factors. The proposed metrics are validated through a practical framework. The outcome shows that the proposed metrics satisfy most of the parameters required by the practical framework hence establishing them as well structured.Article Citation - Scopus: 8Software Product System Model: a Customer-Value Oriented, Adaptable, Devops-Based Product Model(Springer, 2022) Altunel, H.; Say, B.DevOps pipelines have brought notable advantages, such as fast and frequent software delivery to software production paradigms, but dynamically dealing with quality attributes desired by the customer employing a DevOps pipeline remains a challenge. This work aims to define the design of a systems thinking inspired model, called Software Product System Model (SPSM), applying a customer-value oriented, holistic approach for implementing quality requirements, and its application and evaluation in a large software house. The main features include dynamic control of quality gates, the parameters of which are driven by customer requirements and feedback from surveys. All of the inputs are collected in a product backlog and fed forward to the quality gates over the DevOps pipeline. SPSM was successfully deployed in a large software house extending a DevOps pipeline with an accompanying improvement of customer-value oriented key performance indicators for projects. In a 2-year-long case study, security and code quality were the main quality attributes, with the metrics on security vulnerabilities and unit test coverage. At the end of the 2020, the DevOps pipeline within SPSM provided a 69.50% decrease of security vulnerabilities of all software products, and a 29.43% increase in unit test coverage for the whole code base for increasing code quality. At the end of 2020, the project completion ratio was measured to be 99.50% and the Schedule Performance Index (SPI) was measured to be 99.78% as the average of 762 projects delivered. The flexibility of SPSM allowed the software house to adapt to changing customer expectations. A checklist is provided for the replicability of the model application. © The Author(s), under exclusive licence to Springer Nature Singapore Pte Ltd 2021.Article Measuring the Reusable Quality for Xml Schema Documents(Budapest Tech, 2013) Thaw, Tinzar; Misra, SanjayeXtensible Markup Language (XML) based web applications are widely used for data describing and providing internet services. The design of XML schema document (XSD) needs to be quantified with software with the reusable nature of XSD. This nature of documents helps software developers to produce software at a lower software development cost. This paper proposes a metric Entropy. Measure of Complexity (EMC), which is intended to measure the reusable quality of XML schema documents. A higher EMC value tends to more reusable quality, and as well, a higher EMC value implies that this schema document contains inheritance feature, elements and attributes. For empirical validation, the metric is applied on 70 WSDL schema files. A comparison with similar measures is also performed. The proposed EMC metric is also validated practically and theoretically. Empirical, theoretical and practical validation and a comparative study proves that the EMC metric is a valid metric and capable of measuring the reusable quality of XSD.Conference Object Citation - WoS: 1Error Density Metrics for Business Process Model(Ieee, 2009) Tonbul, Gokcen; Misra, SanjayIn this paper, metrics for business process model (BPM), are proposed, which are capable to measure the usability and effectiveness of BPMs. The proposed model is adapting error density metrics to BPMs by considering the similarities between the conceptual characteristics of BPMs and software products. We applied seven software metrics for evaluating quality of business processes/process models. Results show that our metrics help the organization to improve their process, as weighted measurements are indicators for unexpected situations/behaviour for business processes.Conference Object Citation - Scopus: 5Complexity Metrics for Cascading Style Sheets(2012) Adewumi,A.; Misra,S.; Ikhu-Omoregbe,N.Web applications are becoming important for small and large companies since they are integrated with their business strategies.
