An analysis system for biological samples is disclosed that includes at least one analyzer with an analytical unit for analyzing the biological samples and an analyzer controller. The analysis system further includes an analyzer data management system (ADMS) operable for receiving a selection of an operating environment chosen from multiple operating environments. In some embodiments, an analytical system is provided which offers a switch between sample testing and software validation on the same hardware, thereby offering efficiency and flexibility. For example, if sample testing is typically restricted to a particular time of the day (e.g., blood banks often get their samples in the evening and conduct the sample testing at night), the daytime hours can be used to validate new software. In such a case, additional instruments for software validation are not required and expensive idle times of analytical systems are reduced.
