Multiple sclerosis (MS) is a chronic neurological condition affecting around 2.2 million people worldwide. The illness includes a range of symptoms, with fatigue considered to be one of the most disabling. This paper describes how a pragmatic and iterative approach, supported by usability and resonance testing, was used to build a minimum viable product of MS Energize—or MS Energise in UK English regions. MS Energise is a mobile application focused on self-management of fatigue for people with MS. The iterative approach included various stages of testing, during which user feedback including comments about interface, navigation and content, was sought to inform incremental app development and continual improvement. Usability testing was conducted with 11 people with longstanding multiple sclerosis in New Zealand and the United Kingdom, and focused on particular sections of the app as well as the accessibility of the app to users with MS. Two participants contributed to further resonance testing post-release to ensure the app was perceived as relevant and useful to the user. The usability testing and resonance testing phases suggested that user experience of MS Energise was mostly positive. Participants provided a number of suggestions for improvements to aspects of content and design; some of which we implemented during our app development process. Findings will also contribute to future planning and design iteration to enhance the user experience. The next step is further improvement of MS Energise prior to a trial of its clinical and cost effectiveness.

多发性硬化症（MS）是一种慢性神经系统疾病，影响着全世界约220万人。该疾病包括一系列症状，疲劳被认为是最致残的疾病之一。本文介绍了如何在实用性和共振测试的支持下采用务实和迭代的方法来构建MS Energize或MS Energize在英国英语地区的最低可行产品。MS Energize是一款移动应用程序，专注于MS患者的疲劳自我管理。迭代方法包括测试的各个阶段，在此过程中，寻求用户反馈（包括有关界面，导航和内容的评论）来为增量应用开发和持续改进提供信息。在新西兰和英国，对11位长期患有多发性硬化症的人进行了可用性测试，并着重于应用程序的特定部分以及具有MS的用户对应用程序的可访问性。两名参与者为发布后的进一步共振测试做出了贡献，以确保该应用被认为对用户相关且有用。可用性测试和共振测试阶段表明，MS Energize的用户体验大多是积极的。与会者提出了一些改进内容和设计方面的建议；其中一些是我们在应用开发过程中实施的。调查结果还将有助于将来的计划和设计迭代，以增强用户体验。下一步是在临床和成本效益试验之前进一步改进MS Energize。两名参与者为发布后的进一步共振测试做出了贡献，以确保该应用被认为对用户相关且有用。可用性测试和共振测试阶段表明，MS Energize的用户体验大多是积极的。与会者提出了一些改进内容和设计方面的建议；其中一些是我们在应用开发过程中实施的。调查结果还将有助于将来的规划和设计迭代，以增强用户体验。下一步是在临床和成本效益试验之前进一步改进MS Energize。两名参与者为发布后的进一步共振测试做出了贡献，以确保该应用被认为对用户相关且有用。可用性测试和共振测试阶段表明，MS Energize的用户体验大多是积极的。与会者提出了一些改进内容和设计方面的建议；其中一些是我们在应用开发过程中实施的。调查结果还将有助于将来的规划和设计迭代，以增强用户体验。下一步是在临床和成本效益试验之前进一步改进MS Energize。与会者提出了一些改进内容和设计方面的建议；其中一些是我们在应用开发过程中实施的。调查结果还将有助于将来的规划和设计迭代，以增强用户体验。下一步是在临床和成本效益试验之前进一步改进MS Energize。与会者提出了一些改进内容和设计方面的建议；其中一些是我们在应用开发过程中实施的。调查结果还将有助于将来的规划和设计迭代，以增强用户体验。下一步是在临床和成本效益试验之前进一步改进MS Energize。
