I am relatively new to Newforma and have successfully used NIX with two consultants who didn’t know anything about it. In both cases, I managed their expectations. I called/emailed them and said “I am about to add you to this project in NIX…” explained everything and told them to expect an email. After that, both jumped on the site and both have said the process was very easy. Oh, and I didn’t give them NIX access until they needed NIX access - that is a good approach for first timer’s.
I suggest that one of the answers to this post is improved contact management. Newforma cannot do all of those things for us. If it is your contact’s first interaction with Newforma, then tell them what you are about to do. And, use it to market your firm, I did, “We are introducing a new product that will improve our file transfer and give us all a tool for design and construction. It is very easy to use and free, just log on, etc…”. Worked great and I ended up looking like an innovator to them…
