The article introduces a new concept called abstract component to help with creating software components that can adapt to different needs. This concept, along with techniques like component description language and management, forms a model called JBCOM/E that can handle different variations in software. The researchers demonstrated this model with a case study on a POS software platform, showing how it can be used to quickly develop new POS systems. Overall, the article focuses on improving software development by addressing variability in different domains.
