Beta for business?

One of the greatest things about the internet is its speed of development. With the amount of open source code and application development platforms around, its becoming increasing easy for developers to produce new web based services and applications. It’s also becoming more common for these products and services to be produced by smaller companies without the resources to fully test them in-house prior to launch, so they come out as a public or invite only beta's first.
So what does it mean to be a beta tester? Typically a vendor will give you full access to their product or services before releasing it to the rest of the world, so you get to see it first and can work out if you can use it to your advantage before your competitors, in exchange you’ll have to report any bugs and give them some feedback.
Other advantages include, having the opportunity to have a say in the development of the service, it’s more likely that developers will include features you may want to see added, if your talking to them as they develop the service.
On the other hand this does come at a cost, the product is likely to have a few bugs, you may loose some or all of your data, the service is likely to be down at least some of the time and may be changed without notice, the service may even be dropped altogether, it could cause your machine to crash more often and you’ll have to spend a bit of time giving them feedback.
I have been Beta testing operating systems, applications and internet services for the past 10 years or so, and as an IT manager this has been OK on the whole. Sure I’ve been up half the night rebuilding my workstation or recovering lost data on more than one occasion, but i’ve also learned a lot in the process and its helped me find some fantastic solutions for my uses.
Would I like my users to become Beta testers? Probably not. It’s not only that they would need more of my time to support them, or that managing support would be that bit harder, but typically because when users want to beta test a product its because they want to work differently to their colleagues which causes real problems when implementing working practices.
There are beta version of new web based services and applications coming out everyday, the question is how many of these could really make a difference to your business, and is it worth making the effort to try, or should you leave it to other s and wait for the final release.
