You can put all the modern business process in place and expect your business to turn around producing positive results. Most business owners forget that it's the people who has to embrace the change & new system to make everything work successfully. This is where the job of technical evangelist's comes in. As an evangelist - I focus on how to make people comfortable with change. Please bear in mind as a human being it's a natural process to resist change. But if we know the core reason for that resentment - it can be easily addressed. It all comes down to educate the users properly and bring them to the improvements.
As a technical evangelist I plan, prepare and conduct session to bring in users to common platform where system and people can work together. This harmony results immediate performance gain which can be measured and results can be seen. This is no ordinary staff development programme - rather than focusing on people how they benefit from IT systems and how it positively affects them.
