应用改变IT
|
成功典型：医疗保健服务提供商学会从终端用户角度出发 CHRISTUS在IT方面同样面临着许多其他企业曾经面对过的常见挑战：其应用需为多种不同的受众群体提供服务，包括患者、供应链合作伙伴、员工，当然还有保健服务提供机构。该公司管理分散，跨越许多地区，而且正不断推动完全以电子健康档案取代传统病历的工作。 受众多种多样，他们使用的设备也种类繁多，因此，要实现上述目标的复杂性也在日益提高。处于数据中心和终端用户之间的这一系列复杂的服务就是所谓的应用实现链（ADC）。这个链条的任何环节都可能出问题，后果可能是应用崩溃，也可能导致不同地区的用户访问页面所需时间产生巨大差异。 CHRISTUS面临的压力更甚于普通企业，因为医疗设备可不能出错，为医师及临床医生提供精确健康档案或其他信息的应用软件也必须运行完美，不容出现任何闪失。 |
Case-in-point: Health Services Provider Takes End-User Perspective CHRISTUS exhibits many of the common IT challenges organizations face: its applications serve multiple audiences including patients, supply chain partners, employees and, of course, health care providers. It's a decentralized organization with many geographic locations and moving ever closer to full automation of electronic health records (EHR). Inherent in this challenge is the growing complexity involved in delivering applications to multiple audiences using a variety of devices. This complex set of services standing between data centers and end-users is what we call the Application Delivery Chain (ADC). Problems can occur at any point along this chain, and can result in failed applications or page load times that vary widely across geographies. CHRISTUS has the added pressure of knowing that, just as medical equipment cannot fail, the applications providing its physicians and clinicians with accurate health care records or other information must operate flawlessly. |

CHRISTUS如何应对这些挑战呢？由于该公司完全理解应用实现链与收入之间的关系，它已经属于“先进”阵营。该公司用以解决这些复杂挑战的策略读起来堪称“改善应用性能”的教科书： •首先是确定应用性能的标准，这意味着根据用户的需求，明确界定什么样的应用运行速度可以接受，低于何种标准则不能接受。 •随后启动动态的评估计划，评估终端用户体验，确保用户体验能够达到企业的标准。 •为了确保迅速发现问题、解决问题，该公司整个应用实现链都做到了透明化。“这种深入的了解使CHRISTUS可以在应用打造完成并影响到终端用户之前就能对它们进行有效的测试，”CHRISTUS首席信息官乔治•康克林说。他还补充道：“它使我们得以跟上公司系统日益复杂化的趋势和终端用户不断提高的期望值。” |
How does CHRISTUS address these challenges? Since the organization fully understands the connection between application delivery and revenue, it is already in the 'proactive' camp. Its strategy for addressing these complex challenges reads like a best practice playbook in application performance: • It starts by benchmarking its application performance. This means clearly defining what is, and what is not, acceptable application speed, based on the needs of its users. • It then engages a program of ongoing measurement of the end-user experience to make certain that it meets the organization's standards. • To ensure that problems are quickly identified and resolved, it has visibility across the entire Application Delivery Chain. "This deep-dive view allows CHRISTUS to effectively test applications before they are built, and before end-users are impacted," says George Conklin, CIO for CHRISTUS Health. "This allows us to keep pace with the expanding complexity of our systems and the growing expectations of our end-users," added Conklin. |
