Technically, no, they are not mandatory for making a measurement, and depending on your level of skill and need, you might only be aiming for accuracy and knowing that the measurement you have is close to the true value of what you are measuring. However, in order to have the best quality measurement, you do need both accuracy and precision. Just knowing the value you found is close to the true value is not enough when you require higher levels of measurement skill. You will also want a measurement system that is able to repeat those accurate measurements again and again, thus creating precision. No matter how simple or complex your measurement system may be, striving for both accuracy and precision ensures that you have the best measurements possible.
