Nowadays, the software industry is faced with challenges regarding complexity, time to market, quality standards and evolution. To face those challenges, two strategies that are gaining interest both in academy and industry are Service Oriented Architecture (SOA) and Software Product Lines (SPL). While SOA aims at building applications from an orchestration of services, SPL consists in building a set of coreassets and a derivation strategy based on such assets. Adopting such approaches involves important challenges with regard to existing software artifacts that must be transformed in order to respect an architecture that focus on modularity and reuse. This paper presents an industrial experience of such transformation. We propose a non-intrusive reverse engineering process for the development of modular services obtained automatically from existing software artifacts, and a variability-driven derivation process to assembly products out of such services. To validate our approach, we have implemented the reverse engineering and derivation processes using real software JEE artifacts from a component framework of reusable functionalities in several different enterprise applications. The results show important benefits in terms of the development time and flexibility.

This paper presents the practical experience and results of the Lion Project, which aimed to improve software development times at Heinsohn Business Technology (HBT), a large-scale Colombian software development company. The main result of this project is the LionWizard Framework, a set of libraries and tools with a focus on large-scale software reuse and integration. The Lion- Wizard Framework integrates all of the existing libraries at HBT using Maven and provides a Wizard. The latter uses code generation and program transformation to automatically integrate all of the required components into an initial codebase in Java EE. The Wizard provides sufficient exibility to seamlessly integrate future components into the development process. Before the Lion Project, software developers required several days of even weeks to integrate all of the required components into a code base for each project. This new framework reduces those times to a few hours.

Software Product Line engineering aims at reusing and automating software development to reduce costs, have shorter development cycles, and maintain quality. However, for organizations with settled development processes and a large code base, adopting an SPL approach may prove to be a daunting task. In this paper we present an industrial experimentation and a proposal for an SPL adoption in Heinsohn Business Technology (HBT), a software development company specialized in financial, transportation, mortgagebacked securities, and pension-fund solutions. We start by identifying and modeling multiple levels of variability inherent to the kind of developments undertaken by HBT. Next, we define restrictions inside every level as well as between the levels to fully characterize an HBT software product. To limit the impact on the organization development process, we use an extractive approach. This allows us to design core assets starting from current software artifacts. The overall approach is based on real-world software artifacts developed over the years by HBT, whose combinations result in approximately 4.88e11 possible product configurations.
