B. Expected component (III): Will typically be implemented. Expected components include specific and generic practices, which provide guidance on how to achieve required goals.
C. Informative component (I): Supports the understanding. Informative components provide details that help organisations understand and implement the required and expected components effectively, such as sub-practices and example work products.
