The aim of any curriculum is to produce industry ready students. The effectiveness of curricular activities, thus, can be measured by the performances of fresh graduates at their job sectors. To evaluate the Software Engineering (SE) syllabus, Institute of Information Technology (IIT), University of Dhaka, has taken an initiative, under the project IQAC, HEQEP, where a survey based study has been performed. The uniqueness of this SE syllabus is having a six month long internship semester inside the curriculum. Considering all the other courses and activities as traditional, the outcome of the study can fairly be considered as the effect of the Internship program. The result shows that the students having internship experiences, performed above the level of expectation from the industries.

Due to dynamic nature of current software development methods, changes in requirements are embraced and given proper consideration. However, this triggers the rank reversal problem which involves re-prioritizing requirements based on stakeholders' feedback. It incurs significant cost because of time elapsed in large number of human interactions. To solve this issue, a Semi-Automated Framework for soFtware Requirements priOritizatioN (SAFFRON) is presented in this paper. For a particular requirement, SAFFRON predicts appropriate stakeholders' ratings to reduce human interactions. Initially, item-item collaborative filtering is utilized to estimate similarity between new and previously elicited requirements. Using this similarity, stakeholders who are most likely to rate requirements are determined. Afterwards, collaborative filtering based on latent factor model is used to predict ratings of those stakeholders. The proposed approach is implemented and tested on RALIC dataset. The results illustrate consistent correlation, similar to state of the art approaches, with the ground truth. In addition, SAFFRON requires 13.5-27% less human interaction for re-prioritizing requirements.

The potential benefit of migrating software design from Structured to Object Oriented Paradigm is manifolded including modularity, manageability and extendability. This design migration should be automated as it will reduce the time required in manual process. Our previous work has addressed this issue in terms of optimal graph clustering problem formulated by a quadratic Integer Program (IP). However, it has been realized that solution to the IP is computationally hard and thus heuristic based methods are required to get a near optimal solution. This paper presents a Genetic Algorithm (GA) for optimal clustering with an objective of maximizing intra-cluster edges whereas minimizing the inter-cluster ones. The proposed algorithm relies on fitness based parent selection and cross-overing cluster elements to reach an optimal solution step by step. The scheme was implemented and tested against a set of real and synthetic data. The experimental results show that GA outperforms our previous works based on Greedy and Monte Carlo approaches by 40% and 49.5%.

Performance Testing is critical for applications like web services and e-commerce platforms to ensure enhanced end user experience. In such cases, starting to test the system's performance early should significantly reduce the overall development cost. Test-first Performance (TFP) is one such paradigm that allows performance testing right from the early stage of development. Given such potential benefit, this paper proposes the design of a testing framework IVRIDIO which introduces TFP as a Service (TFPaaS). IVRIDIO incorporates the Plugin for TFP in the Cloud (PTFPC) aiming to provide instant feedbacks - a prime requirement of TFP to immediately fix critical performance issues. Furthermore, the Convention over Configuration (CoC) design paradigm has been applied by introducing a configurable project template to maintain TFP test cases. The prototyping details of the framework are given and the variation of response time to the inclusion of PTFPC has also been discussed. The Summated Usability Metric (SUM) score has been provided so that it can later be used for comparing the PTFPC plugin's usability.
