Leveraging Global Resources: A Process Maturity Framework for Managing Distributed Software Product Development

Distributed software development is pervasive in the software industry as companies vie to leverage global resources. However popular quality and process frameworks do not specifically address the key processes needed for managing distributed software development. We develop an evolutionary process maturity framework for globally distributed software development that incorporates 24 new key process areas essential for managing distributed software product development We test the validity of our process framework using data collected from more than sixty large, distributed enterprise product development projects. We believe we have laid new ground for software process research by extending generic quality process frameworks to address the distributed development scenario

Applying Agile Lean to Global Software Development

Although challenges of Global Software Development (GSD) are well known in the industry, practitioners and the organizations look for ways to improve results and overcome challenges. Companies have tried to implement many workable solutions possible to solve issues like poor communication, lack of trust, low morale and many other such issues prevalent in the distributed setting. With the success of agile, the methodology gained interest in leveraging its benefits to alleviate some of these challenges. Similarly, lean was also implemented in distributed software development to resolve issues. While each methodology provided some improvement in the results achieved in global software development, many issues persisted and the desired growth/results were not received. Recent years have seen an increased interest of applying a combination of agile and lean software development paradigms to resolve current industry issues in the area and meet the needs of rapid changing environment. This study aims to study the current practices of the combination of agile lean existing in the industry and how it can be utilized in the global software development. The study focuses on challenges faced to implement agile lean and successful sustainable implementation of agile lean in an environment of global software development

Experimental performability evaluation of middleware for large-scale distributed systems

We present a tool for experimental evaluation of distributed software that enables performability tests to be incorporated in the agile development of complex middleware systems. The proposed approach combines simulation with the profiling of key components and is achieved by an extension to a standard simulation kernel and reflection, thus leveraging existing simulation models and easing the integration of existing components. The evaluation of database replication middleware in large-scale systems is used to illustrate the approach.Fundação para a Ciência e a Tecnologia (FCT) - Project StrongRep (POSI/CHS/41285/2001)

Why3-do: The way of harmonious distributed system proofs

We study principles and models for reasoning inductively about properties of distributed systems, based on programmed atomic handlers equipped with contracts. We present the Why3-do library, leveraging a state of the art software verifier for reasoning about distributed systems based on our models. A number of examples involving invariants containing existential and nested quantifiers (including Dijsktra’s self-stabilizing systems) illustrate how the library promotes contract-based modular development, abstraction barriers, and automated proofs.The development of Why3-do was initiated during a visit of the second author to the Toccata team at Inria Saclay-ˆIle-de-France/LRI Univ Paris-Saclay/CNRS and greatly benefited from the team’s hospitality and Why3 expertise. This work is financed by the ERDF – European Regional Development Fund through the North Portugal Regional Operational Programme - NORTE 2020 Programme and by National Funds through the Portuguese funding agency, FCT - Fundação para a Ciência e a Tecnologia within project NORTE-01-0145-FEDER-028550 - PTDC/EEI-COM/28550/2017

Naked Object File System (NOFS): A Framework to Expose an Object-Oriented Domain Model as a File System

We present Naked Objects File System (NOFS), a novel framework that allows a developer to expose a domain model as a file system by leveraging the Naked Objects design principle. NOFS allows a developer to construct a file system without having to understand or implement all details related to normal file systems development. In this paper we explore file systems frameworks and object-oriented frameworks in a historical context and present an example domain model using the framework. This paper is based on a fully-functional implementation that is distributed as free/open source software, including virtual machine images to demonstrate and study the referenced example file systems

Leveraging simulation practice in industry through use of desktop grid middleware

This chapter focuses on the collaborative use of computing resources to support decision making in industry. Through the use of middleware for desktop grid computing, the idle CPU cycles available on existing computing resources can be harvested and used for speeding-up the execution of applications that have “non-trivial” processing requirements. This chapter focuses on the desktop grid middleware BOINC and Condor, and discusses the integration of commercial simulation software together with free-to-download grid middleware so as to offer competitive advantage to organizations that opt for this technology. It is expected that the low-intervention integration approach presented in this chapter (meaning no changes to source code required) will appeal to both simulation practitioners (as simulations can be executed faster, which in turn would mean that more replications and optimization is possible in the same amount of time) and the management (as it can potentially increase the return on investment on existing resources)

A Blockchain-Based Framework for Distributed Agile Software Testing Life Cycle

A blockchain-based framework for distributed agile software testing life cycle is an innovative approach that uses blockchain technology to optimize the software testing process. Previously, various methods were employed to address communication and collaboration challenges in software testing, but they were deficient in aspects such as trust, traceability, and security. Additionally, a significant cause of project failure was the non-completion of unit testing by developers, leading to delayed testing. This paper integration of blockchain technology in software testing resolves critical concerns related to transparency, trust, coordination, and communication. We have proposed a blockchain based framework named as TestingPlus. TestingPlus framework utilizes blockchain technology to provide a secure and transparent platform for acceptance testing and payment verification. By leveraging smart contracts on a private Ethereum blockchain, TestingPlus can help to ensure that both the testing team and the development team are working towards a common goal and are compensated fairly for their contributions.Comment: 4 figures, 12 page
