During the 17th Century or (early modern period of Europe), the Journeyman
was a person who had gained the craft knowledge and skills comparable with today's Tradesperson. Although the process of acquiring those trade skills today is vastly different to what it was then in terms of industry, technology, information and application (to name but a few), the essence of gaining a trade qualification and the technical experience that followed, is essentially the same now as it was back then!
The term Journeyman referred to the journey or travels that a qualified tradesperson would embark upon to gain the experience necessary to build on the skills that they had acquired under the guidance of a Master Journeyman. These days, when you consider how organisations typically transition technically capable people (individual contributors) who have demonstrated the ability to collaborate and handle additional responsibilities, into a first-level management position that is, moving from 'managing one's self' to managing others', it is tempting to compare the 'individual contributor' to 'manager' transition, with the origins of the Master Journeyman.
