Texts should be created, shared, and edited in a Wiki, not in Word or within e-mails

Within a company there can be many approaches for the development of texts as well as the sharing of texts for further revision. We could, for example, write a text in Word and then load the final version into the enterprise wiki. We could also send around texts by e-mail, asking colleagues to read them and, if necessary, to make changes. But we could also develop a text directly within a wiki. What should we think of this particular work process?
