挑战

andagon GmbH 需要为部署任务关键型 SAP 应用程序的客户提供经济高效的软件测试服务。他们还需要优化软件性能，最大限度地减少应用程序故障，减少系统停机时间，并实施公认的软件质量措施。

关于客户

andagon GmbH 是一家专门从事质量保证和软件测试的咨询公司。他们帮助客户实施测试自动化和质量保证流程，重点关注 SAP 应用程序。他们拥有 50 多名质量专家，并提供全面的定制测试服务。

解决方案

andagon 利用 IBM Rational Performance Tester 和 IBM Rational Performance Tester Extension for SAP Solutions 来评估 SAP 应用程序性能。他们为每个场景制定定制的测试计划，并使用该软件自动执行性能测试并生成所需的工作负载。他们还使用自定义 Java 代码和集成的 Eclipse Java 开发环境来实现高级测试场景。

运营影响

At the wholesale logistics company, andagon was able to identify slow transactions that by themselves appeared to be insignificant yet could potentially cause the business process to freeze. Thanks to the comprehensive performance test, the company was able to identify and investigate the performance limitations of the equipment used in its shipping department and successfully eliminate the issues that would have caused severe business disruptions in production operations. With detailed performance reports, the project team was able to provide the application developers with accurate feedback about bottlenecks and performance issues, which led to optimizations in customized SAP ERP functionality. As a result, the company was able to avoid the delay and expense of application re-engineering, and avoid the cost of new processor and memory resources, in the certainty that the new solution was able to handle peak workloads, comfortably.

数量效益

Application throughput was improved by 100 percent, from 6,000 units per day to 12,000 units per day.
In a second project, it was ensured that a certain operation was completed in less than one second for 90 percent of all users.
For another customer, the stability of an application was proven with a test running over one week to detect memory leaks and other application issues that cannot be detected with simple test cases.

Predictive Maintenance for Industrial Chillers

For global leaders in the industrial chiller manufacturing, reliability of the entire production process is of the utmost importance. Chillers are refrigeration systems that produce ice water to provide cooling for a process or industrial application. One of those leaders sought a way to respond to asset performance issues, even before they occur. The intelligence to guarantee maximum reliability of cooling devices is embedded (pre-alarming). A pre-alarming phase means that the cooling device still works, but symptoms may appear, telling manufacturers that a failure is likely to occur in the near future. Chillers who are not internet connected at that moment, provide little insight in this pre-alarming phase.
