Evaluating a Text Simplification Model's Performance

A research team is developing a model to automatically simplify complex legal documents into plain language. They decide to frame this as a sequence-to-sequence learning problem using an encoder-decoder architecture. Which of the following is the most critical requirement for training this model to perform the simplification task effectively?

You are tasked with developing a model to automatically simplify technical documentation for a general audience. Arrange the following key stages of this project into the correct logical sequence.
