Article Citation - WoS: 7Citation - Scopus: 10Unified complexity measure: a measure of complexity(Natl Acad Sciences india, 2010) Misra, Sanjay; Akman, Ibrahim; Computer EngineeringThis paper proposes a new complexity metric. The proposed metric is a unified complexity measure (UCM) and includes all major factors responsible for the complexity of a program including cognitive aspects. The applicability of the measure is evaluated through empirical, theoretical and practical validation processes. The test cases and comparative study prove its soundness and robustness.Conference Object Citation - WoS: 3A New Complexity Metric Based on Cognitive Informatics(Springer-verlag Berlin, 2008) Misra, Sanjay; Akman, IbrahimIn this paper, a new complexity metric based on cognitive informatics is proposed for object oriented(OO) code. This is the single metric, which covers cognitive complexity of the OO system, method complexity and complexity due to inheritance together. The proposed metric was evaluated against Weyuker set of measurement principles. It was found that seven Weyuker properties are satisfied by this measure.Conference Object Citation - WoS: 3Effective Project Leadership in Computer Science and Engineering(Springer-verlag Berlin, 2009) Cafer, Ferid; Misra, SanjayProject leaders are the most important individuals in projects. A project leader should follow some thinking styles and values which can lead his or her team to success. There is a common notion among software specialists that the more complex a project manager thinks, the better his leadership is. In this paper, we discuss the significance of simple thinking in project leadership. If the leader thinks in a simple way, then the risk of being suffocated in details is less. Complex thinking brings out greater risks of losing the general control of the system because of spending too much time and effort on details and, as a result, more confusion. Not only simplicity, but also psychological factors are important in guiding teams and developing projects in the most effective way. Here, we present a set of qualities for a good project leader in software engineering. In addition to that, we also demonstrate how cognitive and ethical issues affect leadership qualities.Article Citation - WoS: 32Citation - Scopus: 46Weighted Class Complexity: a Measure of Complexity for Object Oriented System(inst information Science, 2008) Misra, Sanjay; Akman, K. Ibrahim; Computer EngineeringSoftware complexity metrics are used to predict critical information about reliability and maintainability of software systems. Object oriented software development requires a different approach to software complexity metrics. In this paper, we propose a metric to compute the structural and cognitive complexity of class by associating a weight to the class, called as Weighted Class Complexity (WCC). On the contrary, of the other metrics used for object oriented systems, proposed metric calculates the complexity of a class due to methods and attributes in terms of cognitive weight. The proposed metric has been demonstrated with 00 examples. The theoretical and practical evaluations based on the information theory have shown that the proposed metric is on ratio scale and satisfies most of the parameters required by the measurement theory.Conference Object Citation - WoS: 14A Suite of Cognitive Complexity Metrics(Springer-verlag Berlin, 2012) Misra, Sanjay; Koyuncu, Murat; Crasso, Marco; Mateos, Cristian; Zunino, AlejandroIn this paper, we propose a suite of cognitive metrics for evaluating complexity of object-oriented (OO) codes. The proposed metric suite evaluates several important features of OO languages. Specifically, the proposed metrics are to measure method complexity, message complexity (coupling), attributes complexity and class complexity. We propose also a code complexity by considering the complexity due to inheritance for the whole system. All these proposed metrics (except attribute complexity) use the cognitive aspect of the code in terms of cognitive weight. All the metrics have critically examined through theoretical and empirical validation processes.Conference Object Citation - WoS: 8A Model for Measuring Cognitive Complexity of Software(Springer-verlag Berlin, 2008) Misra, Sanjay; Akman, IbrahimThis paper proposes a model for calculating cognitive complexity of a code. This model considers all major factors responsible for (cognitive) complexity. The practical applicability of the measure is evaluated through experimentation, test cases and comparative study.Article Citation - WoS: 3Citation - Scopus: 3The Impact of Cognitive and Socio-Demographic Factors at Meetings During Software Development Process(Univ Osijek, Tech Fac, 2011) Akman, Ibrahim; Misra, Sanjay; Altindag, Tugba; Computer EngineeringMost of the important decisions are taken at team meetings during software development process (SDP) and the way of thinking of project leader plays an important role in achieving quality objectives at these team meetings. Considering this important issue, this paper investigates the impact of cognitive and socio-demographic factors on manager's simple thinking style towards improving the quality of team meetings in SDP. We have performed experimentations among Information and Communication Technologies' (ICT) senior professionals and managers from government and private sector organizations for this purpose. The hypotheses have been developed under different empirical categories and then statistical analysis techniques have been used to draw inferences. The results indicate that "type of team meetings", "project leader's cognitive characteristics" and "adoption of a cognitive model at team meetings" have statistically significant impact on manager's simple thinking in terms of improving productivity and contribution of team meetings.
