Justification
1. 2. These are the criteria by which you will judge your system to be a success or not. Each individual criterion will need to be justified as to why it is important that you check it later on!

Is everything that should be on a report / form on it? Do all the validation checks function as expected? Do all the navigation buttons work? Do the correct prices come up when different options are selected? Are calculations performed correctly? If the database needs to be filtered – do the filters work?
