For a variety of professionals, from designers to executives, the value of a good drawing and wireframing tool cannot be overstated.

Whether they're used for producing user interface mock-ups or designing complex workflows and org charts, products like Omnigraffle, Mockingbird and literally dozens of others are available for quickly and efficiently creating such documents.

This week SAP expanded the ability of StreamWork, its enterprise 2.0 software-as-a-service, to integrate with other enterprise SAP software. StreamWork released its enterprise edition in December. Up to now its integrations have included SaaS offerings such as Box, Doodle, Evernote, Google Apps, MindMeister and Scribd. Integrating with other enterprise-class SAP software is a major step forward for StreamWork.

Continuing our series on iPad apps for work, today we'll look at document collaboration tools for the iPad.

First of all, the iPad isn't great for this. As Instapaper creator Marco Arment, wrote recently: "The iPad isn't really a great 'office productivity' device, in the traditional PC sense. It can be used that way in some cases, but it's rarely the best tool for the job." That said, there are a few apps that enable you to view, edit and share documents using the iPad.

Today at BlackBerry World in Orlando, FL RIM announced it will add support for managing Android and iOS devices to its BlackBerry Enterprise Server platform. The technology will come from RIM's pending acquisition of ubitexx, which was announced today.

RIM also announced the availability of Gist for BlackBerry. RIM acquired Gist in February. Importantly, it looks like Gist will still be available for other platforms, which was a concern for some users.

These moves imply that RIM is finally moving towards a multi-platform approach to development.

Today Zoho announced Zoho Creator for Google Apps, bringing it total number Google Apps Marketplace offerings to 11 and making it the largest vendor in the marketplace. But more importantly, it is bringing Google Apps users an easy way to build simple applications on top of both the Zoho and Google platforms. There are limitations:

"Currently, there is no option to directly publish Zoho Creator apps within a Google Apps domain," says Zoho evangelist Raju Vegesna. "Google said they will look into this idea." However, Google Apps admins will be able to share apps with users within the domain.

Convofy, the new enterprise collaboration platform we covered last month, opens to the public today. It's launching using a freemium model similar to Yammer's, so you can try it out for free.

We got a demo from CEO Faizan Buzdar yesterday, and it's a solid product. It's unique, fast and has clear value for teams collaborating with visual media such as photos, video or data visualizations. It has a few discrete apps that run on its platform already, including an image gallery and media player. Users can comment on specific elements of an image, website or video. A nice touch is the ability to comment on a portion of a video and create a link that will start the video at the relevant point.

Asana is a company created by Facebook co-founder Dustin Moskovitz and ex-Googler Justin Rosenstein. Its aim is nothing short of reinventing how we collaborate. It's a lofty goal, especially with so many Enterprise 2.0 tools aiming to do just that. But it has deep pockets, high profile advisers, a strong vision and lots of buzz.

The team has been toiling on the project in secret for two years, but have finally started talking about it over the past few months. In February, the company held an open house where Rosenstein demoed and explained the product. It's currently in private beta, but don't hold your breath waiting for an invite.

Here's what you should know about the company and its product.

Six months ago we did an overview of trends in the idea management market. At the time, most of the action was going on in the internal idea/innovation management area. This time around, the new trends are emerging around externally focused idea management solutions.

Each of the three trends we identified six months ago now has a corollary trend.

You dial the conference call number. Or you can copy and paste it into Skype, or just click the link in your phone's e-mail app. Then you have to enter your 12 digit conference ID number, or whatever this particular system calls it. If you're on your phone and away from your computer, maybe you jotted it down on a piece of scrap paper. If not, you need to switch back and forth between your dialer and the app that the ID number.

You punch in the number. You wait. Nothing happens. You realize you forgot to hit pound at the end. OK, pound. The robotic voice on the other end slowly, carefully reads the whole number back to you. Are you sure this is the number you meant to dial? Yes of course it is, stupid robot! You hit "one" to confirm. You wait. Sorry, this access code is incorrect. Please enter your 12 digit conference participant ID access code number followed by pound now. Arh, that wasn't the right number after all. You try again, this time remembering to hit pound. The robot repeats it back to you again and you confirm. Finally, you enter the conference call, a bit late.

Pleasantries are exchanged, the conference gets rolling and then...someone's call gets dropped. Everyone waits for them to dial back in and run the access code gauntlet.
