The company’s consultants help customers across multiple sectors to implement test automation and quality assurance processes including functional testing and performance testing. For those customers developing and using SAP applications, andagon offers a comprehensive range of tailored testing services designed to optimize performance and reliability.

andagon GmbH, a renowned consulting company specializing in software testing, process and test automation, often encounters clients who have identified quality issues or performance bottlenecks during the implementation phase of their applications. These clients turn to andagon to analyze the difficulties and develop a customized test plan to efficiently address the performance issues. In typical commercial environments, software testing is often delayed until the end of a project, increasing the pressure on the testing team and process. To assess the performance of a complex application quickly and effectively, efficient tools are required to create and execute the relevant test cases. Thousands of companies rely on SAP software to run their core business processes, and need to make sure that application errors do not disrupt business operations. Particularly for manufacturing companies, system downtime can cause significant financial damage. If software quality and performance issues are spotted at a late stage in a development project, the costs and delays incurred by corrective work damages companies’ abilities to reach their goals.

andagon advises its customers to integrate testing into general development processes to monitor software quality throughout the project and avoid discovering functional or performance issues at the end of an implementation. As an IBM Business Partner, andagon is a strong advocate of the comprehensive IBM toolset for application development and testing. IBM Rational Performance Tester provides a broad range of features to enable efficient performance testing, and helps to identify application architecture and infrastructure bottlenecks. A simple graphical user interface allows for the creation of test cases without the need to write code, and integrated test data management enables flexible and dynamic customization of test cases. IBM Rational Performance Tester automatically executes tests with dynamically generated test data, and tracks the dynamic data throughout the tests to ensure that correct, useful test results are generated. IBM Rational Performance Tester uses flexible IBM Rational Performance Tester Agents to generate the performance test load. The load test agents emulate user behavior to generate a workload that is as similar as possible to real users.

• 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.

• 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.
