Many different worldwide initiatives are promoting the transformation from machine dominant manufacturing to digital manufacturing. Thus, to achieve a successful transformation to Industry 4.0 standard, manufacturing enterprises are required to implement a clear roadmap. However, Small and Medium Manufacturing Enterprises (SMEs) encounter many barriers and difficulties (economical, technical, cultural, etc.) in the implementation of Industry 4.0. Although several works deal with the incorporation of Industry 4.0 technologies in the area of the product and supply chain life cycles, which SMEs could use as reference, this is not the case for the customer life cycle. Thus, we present two contributions that can help the software engineers of those SMEs to incorporate Industry 4.0 technologies in the context of the customer life cycle. The first contribution is a methodology that can help those software engineers in the task of creating new software services, aligned with Industry 4.0, that allow to change how customers interact with enterprises and the experiences they have while interacting with them. The methodology details a set of stages that are divided into phases which in turn are made up of activities. It places special emphasis on the incorporation of semantics descriptions and 3D visualization in the implementation of those new services. The second contribution is a system developed for a real manufacturing scenario, using the proposed methodology, which allows to observe the possibilities that this kind of systems can offer to SMEs in two phases of the customer life cycle: Discover & Shop, and Use & Service.

全球范围内许多不同的计划正在促进从机器主导制造向数字制造的转变。因此，为了成功地向工业4.0标准转换，制造企业需要实施清晰的路线图。但是，中小型制造企业（SME）在实施工业4.0时遇到许多障碍和困难（经济，技术，文化等）。尽管有几项工作涉及在产品和供应链生命周期领域中结合使用工业4.0技术，中小企业可以将其用作参考，但对于客户生命周期而言并非如此。因此，我们提出了两项​​建议，可以帮助这些SME的软件工程师在客户生命周期的背景下整合Industry 4.0技术。第一个贡献是一种方法论，可以帮助这些软件工程师完成与Industry 4.0一致的创建新软件服务的任务，该服务可以更改客户与企业的交互方式以及与企业交互时的体验。该方法详述了一组阶段，这些阶段分为多个阶段，这些阶段又由活动组成。在这些新服务的实现中，它特别强调了语义描述和3D可视化的结合。第二个贡献是使用建议的方法为实际制造场景开发的系统，该系统允许观察这种系统可以在客户生命周期的两个阶段中为中小型企业提供的可能性：发现和购物以及使用和服务。
