IBM Nederland B. V. Hints and Tips § Use product’s capabilities – Do not fall into the trap of developing it in Java § Optimize the WPS test server – Run scripts to disable Monitor, Fabric, WSRR software components § Split solution into multiple modules – Use libraries for re-usable interfaces and objects – Once interfaces are agreed upon, it is easy to distribute work § Develop iteratively – Quickly test new functionality – Postpone implementation details § Use component/module testing – First test components individually – Add test data to a datapool in WID test client – Possibly create test cases and test suites for repeatable tests – Explore debugging capabilities § User interface – Use BPC explorer for testing and administration – Use Business Space for final demonstration (nice look and feel delivered out-of-the-box. ) § Collect your questions for “vragenuurtje” (date to be confirmed) 60 © IBM Corporation 2009
