Knowledge and System Validation

• Part of the ongoing process is testing.
• You have to assure that two things are right, the knowledge and the system.
• The knowledge you get from an expert may not be right.
• You may translate it incorrectly or they may give it to you incorrectly.
• You can compare with the expert (ask them, interview them), and you can compare with other epxerts.
• Of course you need to validate the system too. You need to check with experts and users.
