Smartsheet is my new favorite tool

I believe this product adds value to my day-to-day work, it is all about collaboration when you work in a global company.

It worked best for me as an online project management tool, mostly because Smartsheet doesn't require the license for people to view/edit the sheets. In the past we've had to provide MS Project license to all users who needed to view the release or implementation plans, otherwise we would have to export these plans in Excel every time when updates were made for those without license. With Smartsheet I can just share the url and that's it. I can also prompt people to update their status from the specific item that needs to be updated. What's most important: everyone knows where the latest version of the project plan lives. In the past one of the release managers would send an email saying she is working on the doc and asking other managers not to update it. The updated project was scheduled to be sent out to our stakeholders on a weekly basis, as it has been too hard to merge all the changes on a daily basis.
Smartsheet is probably less useful, when you need to do a comprehensive data analysis with pivot tables and especially if you have the macro you like to apply. That's where Excel is still a better option. Though these types of documents are rarely of a collaborative nature.
