UPCASE -一种小型组织可用性过程能力的自我评估方法
UPCASE - A Method for Self-Assessing the Capability of the Usability Process in Small Organizations
摘要：
设计可用的产品对于通过用户满意度提供竞争优势非常重要。建立或改进可用性过程的第一步是执行过程评估。由于这可能费用高昂，对于寻求较轻评估的组织，特别是小组织，一个替代办法可能是自我评估。它们可以由组织自己执行，以评估其过程的能力。虽然有特定的评估方法来评估可用性过程，但考虑到小型组织的具体特点，它们都没有提供自我评估方法。本研究的目的是提出一种自我评估的方法，在小型组织的可用性过程的能力。该方法由可用性过程参考模型、测量框架、评估模型和在线工具支持的自我评估过程组成。基于可用性能力/成熟度模型和软件过程自评估方法的系统映射研究，我们确定了这样一种方法的具体要求。UPCASE方法是使用基于ISO/IEC TR 29110和ISO/TR 18529标准的多方法方法系统开发的。通过一系列案例研究，对该方法的可靠性、可用性、可理解性和内部一致性进行了应用和评价。初步结果表明，该方法是可靠的。反馈还表明，该方法易于使用和理解，即使是非软件过程改进专家。UPCASE方法是小型组织对可用性过程进行自我评估的第一步，它支持系统地建立和改进可用性过程，从而有助于提高其软件产品的可用性。
英文摘要：
Designing usable products is important to provide a competitive edge through user satisfaction. A first step to establish or improve a usability process is to perform a process assessment. As this may be costly, an alternative for organizations seeking for lighter assessments, especially small organizations, may be self-assessments. They can be carried out by an organization on its own to assess the capability of its process. Although there are specific assessment methods to assess the usability process, none of them provides a self-assessment method considering the specific characteristics of small organizations. The objective of this research is to propose a method for self-assessing the capability of the usability process in small organizations. The method consists of a usability process reference model, a measurement framework, an assessment model, and a self-assessment process supported by an online tool. Based on systematic mapping studies on usability capability/maturity models and software process self-assessment methods, we identified the specific requirements of such a method. The UPCASE method was systematically developed using a multi-method approach based on the ISO/IEC TR 29110 and ISO/TR 18529 standard. The method has been applied and evaluated with respect to its reliability, usability, comprehensibility and internal consistency through a series of case studies. First results indicate that the method may be reliable. Feedback also indicates that the method is easy to use and understandable even for non-software process improvement experts. The UPCASE method is a first step to the self-assessment of the usability process in small organizations supporting the systematic establishment and improvement of the usability process contributing to the improvement of the usability of their software products.
