The word 'foolproof' means something that is designed so that even a fool, or someone who is not very intelligent, would be able to use it successfully. For example, a foolproof recipe would be one that is so easy to follow that even someone who has never cooked before could make it without any problems. Similarly, a foolproof system or process would be one that is designed to be so simple and easy to use that even someone who is not very knowledgeable about it would be able to use it without making any mistakes.
