Happily surprised by OneNote

Now those who know me know I'm no fan of Microsoft and I certainly have not been convinced by SharePoint but today I saw OneNote being used by a team to capture the day to day project thoughts, decisions and activities. This was done by using OneNote in combination with SharePoint. I have to say for the day to day transient project information this was working really well. The analogy is that they used OneNote as a project notebook that everyone has access to. It was organised by work area and had sub sections, essential a hierarchal file structure. What the team loved was the ease with which they could 'drop' information into it and the ability to move away from email.
Interestingly the person showing me this admitted that this was just a glorified file share. They also thought that OneNote only really worked for the project team. For those on the outside this environment is just too unstructured, maybe a little better than looking through someone else's file share but still with a lot of the same problems.
Now I've been trying to get people to use our corporate wiki to capture their project information and my first thought was 'Wow maybe I've got this wrong and wiki's aren't what is required!'. Then I recognised that different tools are needed for the capture of different levels of information. In this example the OneNote/SharePoint combination was capturing transient day to day information very well. However to capture the more persistent decisions and to support collaborative authoring of project documents then a wiki makes more sense. Finally as the project pass significant stage gates then the wiki page or sections of it can be published into a document repository to give a permanent snapshot of the project status. This model is very attractive as it seems to offer a way to manage the different requirements associated with the capture and sharing of different levels of information. I need to remember that one size does not fit all.
