Hi!
I guess it depends on how 'generalisable' your empirical findings are. For example, Maslow must have seen that so many people experienced a hierarchy within their needs that he could make a model out of their experience that was applicable to virtually all - a theory of sorts, albeit in model form.
My findings mean that I can contribute to overall knowledge, but I don't know that my findings apply to all people, so they remain a contribution rather than a theory.
My experience (education) is that creating a model from your results is A Good Move, so if it's possible to somehow schematise what you have found then you can create 'Nearlyfinished's Model of XYZ'.
Hope this helps!
