Context: End-user service composition (EUSC) is a service-oriented paradigm that aims to empower end users and allow them to compose their own web applications from reusable service components. User studies have been used to evaluate EUSC tools and processes. Such an approach should benefit software development, because incorporating end users’ feedback into software development should make software more useful and usable. Problem: There is a gap in our understanding of what constitutes a user study and how a good user study should be designed, conducted, and reported. Goal: This article aims to address this gap. Method: The article presents a systematic review of 47 selected user studies for EUSC. Guided by a review framework, the article systematically and consistently assesses the focus, methodology and cohesion of each of these studies. Results: The article concludes that the focus of these studies is clear, but their methodology is incomplete and inadequate, their overall cohesion is poor. The findings lead to the development of a design framework and a set of questions for the design, reporting, and review of good user studies for EUSC. The detailed analysis and the insights obtained from the analysis should be applicable to the design of user studies for service-oriented systems as well and indeed for any user studies related to software artifacts.

最终用户服务组合的用户研究

语境：最终用户服务组合 (EUSC) 是一种面向服务的范式，旨在授权最终用户并允许他们从可重用的服务组件组合自己的 Web 应用程序。用户研究已用于评估 EUSC 工具和流程。这种方法应该有利于软件开发，因为将最终用户的反馈纳入软件开发应该会使软件更加有用和可用。问题：我们对什么构成用户研究以及如何设计、进行和报告好的用户研究的理解存在差距。目标：本文旨在解决这一差距。方法：本文对 EUSC 的 47 项选定用户研究进行了系统评价。在审查框架的指导下，本文系统地、一致地评估了每项研究的重点、方法和凝聚力。结果：文章的结论是，这些研究的重点是明确的，但它们的方法论是不完整和不充分的，它们的整体凝聚力很差。这些发现导致了设计框架的开发和一系列问题，用于设计、报告和审查 EUSC 的良好用户研究。详细的分析和从分析中获得的见解应该适用于面向服务系统的用户研究设计，实际上也适用于与软件工件相关的任何用户研究。
