The following is the domain checklist:

• Have standards for development been used (e.g. standard scheme techniques, standards for structured programming, standards for database approach, recognizable nomenclature, and standards for the use of user interfaces)?
• Have check processes (watchdogs) been applied?
• Is the operator able to supply status information?
• Is the data processing split up in sub-transactions?
• Have the input, the processing, and the output been implemented separately?
• Have possible machine dependencies been implemented in separate modules?
• Has the essential functionality been stored in separate modules?
• Have I/O operations been classified in individual modules in order to separate the retrieval of data from the processing of data?
• Are program modules reused?
• Have the programs been structured and are they easy to understand?
• Is open, consistent, and up-to-date technical documentation available?
• Are the subsystems distributed?
• Will the data processing be done dually?
• Have the programs been parameterized?
• Have the algorithms been optimized?
• Can test data be easily restored?
