Relationship networks have to be built up from several different sources. Often it is not clear whether the relationship applies for the whole of a strategy hierarchy or for only some component part. There is a continuing effort to refine such networks, but even when a relationship is contentious the practice is to retain the relationship provisionally rather than exclude it and lose a potential link. This said, it is generally easier to criticize errors of commission than to undertake the extra effort to remedy errors of omission. If there are numerous organizations implementing the strategy, it is best to cite an umbrella body rather than any one.
More recent publications are preferable, if available.
However, publications produced when the strategy was first advocated or formulated may contain better articulations of the dimensions of the strategy. References should be cited within the entry matching their content, not at a narrower or broader level. The title of a pertinent publication may not necessarily correspond to the strategy name. A seemingly pertinent publication title may disguise a totally unfocused content.
