By David Kowalsky, Guest Editor

Do you ever find yourself overwhelmed with trying to keep track of all the versions of a document that are being sent back-and-forth by you and your work colleagues by email? When opening a document to edit, have you ever had the experience of being frustrated by immediately seeing a message pop up telling you that the document is locked? Many companies have introduced features to their products to alleviate these types of issues, making collaborative authoring– projects where written works are created by multiple people together (collaboratively) rather than individually – more attractive and worth investigating.

Document editing is frequently done collaboratively, especially now that it is so typical for companies to have documentation and engineering team members located at different locations throughout the world. Some products even promote editing with real-time technology. But it can be confusing to read marketing material that uses a variety of different terms including, but not limited to: co-authoring (Microsoft), collaborative multi-person editing (Google Cloud Connect for Microsoft Office), and multiple user, online editing (IBM LotusNotes with eXpresso). Each are referring to essentially the same thing: the ability to edit the same document, at the same time, by multiple people at different locations.

The purpose of this article is not to rate the products, but instead to introduce what is available by listing the key product details, with the intention of encouraging further investigation. 

The majority of the products listed below fall into the category Document-centric Authoring, but there are other tools available to help you collaborate on documents, which are in a second category, Other Tools for Collaborating. Finally, there is Purpose Specific Solutions.

What about the future? It is already apparent that collaboration is not stopping with documents. Wikis are becoming more widespread, but even more intriguing is the start up Convofy and Chatter (from SalesForce), which are both pushing for companies to implement private social networks where collaboration in real-time is used for as many workplace functions as possible.

Microsoft Office 2010: Word, PowerPoint, and OneNote

Microsoft Office 2010: Word, PowerPoint, and OneNote (via shared notebooks) co-authoring capabilities enable you to simultaneously edit the same Word 2010 documents and PowerPoint 2010 presentations.
This is after saving and then opening a file online to SharePoint 2010 (business users) or SkyDrive(everyone else).

When someone else opens the same file for editing while you have it open in Word 2010 or PowerPoint 2010, from the same SharePoint or SkyDrive location, you automatically begin a co-authoring session. Automatically see who else is editing and where they are working in the document. Save the document to see changes from other editors as you work. Your changes also become available to other editors each time you save.

When simultaneously editing files with others in Word 2010, the paragraph you are currently editing is automatically blocked to other editors to avoid conflicts. You see who is editing the paragraph and can view their presence (the formal term for availability information – contact card information) and initiate contact from their as well.

If someone makes changes to the same copy of the document when they have it offline, their changes automatically sync the next time they are online and you then see those changes as well.
