This paper discusses the perennial problem of poor requirements and summarises an attempt to mitigate the problem using an object‐oriented approach by developing and using a software tool named Tiger Pro. Next the early results of using Tiger Pro in the classroom are discussed. The major outcome was the transition of the classroom discussion from a focus on the structure of the requirement sentence to a focus on the difficulty of writing a good requirement, or a focus on the content of the requirement sentence. The paper then considers the distinction of structure and content of a requirement and the levels of examination. This can be shown to classify the attributes of a good requirement. The classification of the attributes of a good requirement reveals that the content of an individual requirement is the focus of examination, but requirement management tools focus on the structure of the requirement set. The paper concludes by proposing a structure to capture the information in a requirement that facilitates the writing of better requirements.
