應用改變IT
|
????成功典型：醫療保健服務提供商學會從終端用戶角度出發 ????CHRISTUS在IT方面同樣面臨著許多其他企業曾經面對過的常見挑戰：其應用需為多種不同的受眾群體提供服務，包括患者、供應鏈合作伙伴、員工，當然還有保健服務提供機構。該公司管理分散，跨越許多地區，而且正不斷推動完全以電子健康檔案取代傳統病歷的工作。 ????受眾多種多樣，他們使用的設備也種類繁多，因此，要實現上述目標的復雜性也在日益提高。處于數據中心和終端用戶之間的這一系列復雜的服務就是所謂的應用實現鏈（ADC）。這個鏈條的任何環節都可能出問題，后果可能是應用崩潰，也可能導致不同地區的用戶訪問頁面所需時間產生巨大差異。 ????CHRISTUS面臨的壓力更甚于普通企業，因為醫療設備可不能出錯，為醫師及臨床醫生提供精確健康檔案或其他信息的應用軟件也必須運行完美，不容出現任何閃失。 |
????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如何應對這些挑戰呢？由于該公司完全理解應用實現鏈與收入之間的關系，它已經屬于“先進”陣營。該公司用以解決這些復雜挑戰的策略讀起來堪稱“改善應用性能”的教科書： ?????首先是確定應用性能的標準，這意味著根據用戶的需求，明確界定什么樣的應用運行速度可以接受，低于何種標準則不能接受。 ?????隨后啟動動態的評估計劃，評估終端用戶體驗，確保用戶體驗能夠達到企業的標準。 ?????為了確保迅速發現問題、解決問題，該公司整個應用實現鏈都做到了透明化。“這種深入的了解使CHRISTUS可以在應用打造完成并影響到終端用戶之前就能對它們進行有效的測試，”CHRISTUS首席信息官喬治?康克林說。他還補充道：“它使我們得以跟上公司系統日益復雜化的趨勢和終端用戶不斷提高的期望值。” |
????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. |
