I am aware that I could be not the best man to answer how this could be realized but still have my own reservation, based on my little understanding of the subject matter.
I wrote this topic after I came across some training documentation in the internet and got impressed very much and overwhelmed, didn't know what to say, felt that my country was left out and the cost could be devastating and wanted to share what I came across here, before 2 years, on 30th April, 2019, to be more precise.
I shared a one page graphic representation of the 4 Eras from this document with the head of an IT company in the western countries, whom I met at one occassion and he replied saying "he simply wishes that the relevant decisions makers in the company will realise this potential in due time"
In the country where this company is placed almost every business process has already been automated (successfully realized/reached the stage of business process automation) and digital transformation is in a full swing.
My view is that you can't efficiently realize the Era of Intelligente Enterprise before successfully established the Era of Digital Transformation and you can't jump start from Digital Transformation without already successfully completed (established) Business Process Automation.
The preceeding Era feeds into the following Era, that is my understanding currently.
The last time I visited Ethiopia I went to a government administrative office for some service and they were still carrying around office folder and they asked me to go and buy a "klaster" for my case (the file wrapper that we always used in offices to keep files).
It is unfortunate that we are still keeping killing each other while the rest of the world is already in fierce competition to control the world.
