Software integration model: An assessment tool for global software development vendors

Abstract

The trend toward global software development (GSD) has grown tremendously in recent years because of the rapid acceleration in information and communication technologies (ICTs). The reason for the changing trend toward GSD is to develop high‐quality software with minimum cost and time with round the clock. Despite the benefits gained from GSD, there are certain challenges associated with it. Literature reveals that software integration is an integral challenge in the GSD domain and vendors face numerous difficulties in integrating the software components to build the final product. The main aim of this research study is to develop a software integration model (SIM) that will assist GSD vendors to address the factors linked with various stages of software integration. This model is basically designed for GSD vendor organizations to assess and improve their software integration‐related activities. However, it is also beneficial for GSD client organizations in getting knowledge about the status of the GSD vendor organization's software integration capabilities. The research design is composed of well‐known research strategies including systematic literature review (SLR), questionnaire survey, and case study approach. This research study yielded the SIM. We identified nine critical success factors (CSFs) and 10 critical barriers (CBs) in software integration through SLR‐1 by extracting the data from a sample of 105 papers. Similarly, we also identified a total of 132 practices/solutions, for the identified CSFs and CBs in software integration, through SLR‐2 from a sample of 40 papers. These identified factors and practices were validated from 96 global software industry experts/practitioners through online survey. The identified CSFs, CBs, and their associated practices have been arranged adequately across the six software integration levels of SIM. We have adapted SIM structure from capability maturity model integration (CMMI), implementation maturity model (IMM), and software outsourcing vendors readiness model (SOVRM). We also conducted six case studies in the software industry for SIM applicability and validity. The participants' feedback from the six case studies in GSD vendor's organizations portray that the SIM is beneficial for GSD vendors to assess their software integration capability.

A Conceptual Framework Based on PLS-SEM Approach for Sustainable Customer Relationship Management in Enterprise Software Development: Insights from Developers

“…The empirical findings from the review affirm that both inexperience and a deficiency in domain knowledge affect CRM within the GSD industry. Moreover, these factors significantly contribute to the breakdown of successful CRM applications [113]. Likewise, the other six variables also affect CRM except for geographical distance.…”

Working with agile and crowd: human factors identified from the industry

“…Along with these reasons, it sometimes requires hiring of expertise that may be locality-specific. One of the biggest benefits that can be achieved by GSD is "round-the-clock" development (Ilyas et al, 2024). However, developing software globally is not an easy task and has many challenges and limitations.…”

Challenges and solutions in the development of blockchain applications: Extraction from SLR and empirical study

“…The advent of blockchain technology, which might just be one of the most significant innovations in modern times, gives humans access to new heights of advancement in almost every field of endeavor, but like other technologies, as a result of addressing all of these issues, blockchain adoption will impact the overall economy in positive ways 9,10 . According to Bosu et al, 7 GitHub hosted about six thousand plus active blockchain software project.…”

“…According to Bosu et al, 7 GitHub hosted about six thousand plus active blockchain software project. As the industry experiences rapid growth and accelerated software development, the number of challenges and motivations has also increased 9,11 . This creates a scenario where software quality becomes a significant concern, especially considering the first‐come‐first‐served nature of the blockchain ecosystem 3,7 .…”
