Companies would like to avoid the use of paper and to keep everything on-line. It has their advantages such as efficiency, you do not spend hours to look for a particular document from client, vendor, etc. And of course environmental friendly. So the challenge here is "How to integrate the data from your business in one particular platform? " please take into account that we are taking about a massive corporation. So the challenge is global. The first thing to do is gather all business units across border and to agree in the lay out of the new platform that will integrate all the data. After that is important to create testing environments for all countries. And here it comes the biggest challenge. No everyone speaks ENGLISH. And even though there are plenty of tools to translate such a GOOGLE TRANSLATE and so on. The meaning of the words is not the same across countries specially when it comes to tax regulations. Therefore is important to gather and to make the platform useful for everyone globally. The final step after all integration is training, I would like to keep in mind this cannot be only considered before GO LIVE we should keep the train even after that. Why? because new update in the system, new colleagues, general questions and so on.
