The use of software in mission critical applications poses greater quality needs. Quality assurance activities are aimed at ensuring such quality requirements of the software system. Antifragility is a property of software that increases its quality as a result of errors, faults, and attacks. Such antifragile software systems proactively accepts the errors and learns from these errors and relies on test-driven development methodology. In this article, an innovative approach is proposed which uses a fault injection methodology to perform the task of quality assurance. Such a fault injection mechanism makes the software antifragile and it gets better with the increase in the intensity of such errors up to a point. A software quality game is designed as a two-player game model with stressor and backer entities. The stressor is an error model which injects errors into the software system. The software system acts as a backer, and tries to recover from the errors. The backer uses a cheating mechanism by implementing software Learning Hooks (SLH) which learn from the injected errors. This makes the software antifragile and leads to improvement of the code. Moreover, the SLH uses a Q-Learning reinforcement algorithm with a hybrid reward function to learn from the incoming defects. The game is played for a maximum of K errors. This approach is introduced to incorporate the anti-fragility aspects into the software system within the existing framework of object-oriented development. The game is run at the end of every increment during the construction of object-oriented systems. A detailed report of the injected errors and the actions taken is output at the end of each increment so that necessary actions are incorporated into the actual software during the next iteration. This ensures at the end of all the iterations, the software is immune to majority of the so-called Black Swans. The experiment is conducted with an open source Java sample and the results are studied selected two categories of evaluation parameters. The defect related performance parameters considered are the defect density, defect distribution over different iterations, and number of hooks inserted. These parameters show much reduction in adopting the proposed approach. The quality parameters such as abstraction, inheritance, and coupling are studied for various iterations and this approach ensures considerable increases in these parameters.

Today, IT and especially the development of customer-focused software, has become one of the most important elements for a company to remain competitive. The primary purpose of this article is to determine whether it is possible to improve the agile development of a company by adjusting its software development process in terms of cultural, technical, and managerial dimensions. Based on a literature analysis and practical experience in the company, different influencing factors and parameters, which affect the value creation throughout the software development process of a company were derived and clustered. Out of these clusters, a framework (Agile Method Construction Set) based on a Microsoft Excel questionnaire was created in order to analyze and identify optimization potential in the development process of a company. This construction set was adapted to meet the requirements of the development department of a large Swiss insurance company in order to validate and test the framework with real data.

As one of the largest archipelagic countries in the world, Indonesia has been running the maritime highway system in recent years. This study focuses on how to improve the role of IOT platform in the maritime highway system. Furthermore, in this study, the authors are designing a new IOT system framework to support the operation of the maritime highway program in the seaport logistics system in archipelago countries, especially Indonesia. Each part of the port management stakeholders like port authority, commodity products company, shipping companies, and the government with their different policies (unique) in each island region has created its own IT system and links it to every website in its organization partially and not yet fully integrated. This research provides newly integrated frameworks with the IOT approach, and also a few recommendations related to practical and theoretical contributions that can be further developed in the seaports sector.

Digital evidence has a different meaning from physical evidence, but even though it is different, both are a unity of evidence that supports each other in the investigation process. Unfortunately, laws and regulations generally have not been oriented to the terminology of digital evidence that should be. It becomes a research challenge in how the handling of digital evidence also gets the same treatment as physical evidence. For this reason, technical studies are needed to support the application of law and regulations for digital evidence handling. This article provides a solution in the form of digital evidence cabinets as a framework to support the centralization of digital evidence that following the applicable regulations of procedures for the management of evidence in the territory of Indonesia. This concept can translate the centralization of digital evidence through the analogy of physical cabinet and the interpretation of cabinet, rack, bags, and evidence unit with types of criminals, list of crimes, list of crime scenes and list of digital evidence at one crime scene.
