In a post yesterday, Eli Feldblum makes the assertion that Microsoft seems to prefer to use Flash over Silverlight. He argues this fact is obvious since most of the rich, interactive parts of Microsoft's public sites are using Flash. In fact, he even states that "the software giant seems to be not even trying" to move to Silverlight and goes on to say:

A quick check through Microsoft properties reveals that only the Microsoft Home Page  and the Microsoft Developer Network use Silverlight; MSN Video, Zune.net and the new WWTelescope all use Flash.

The idea that Microsoft isn't interested in using Silverlight on its sites is, of course, completely wrong. However, in Mr. Feldblum's defense, it could certainly seem that way if you make the assumption that any company, including Microsoft, could implement massive technical and creative changes across an incredibly wide swatch of high traffic sites like the ones cited above in a month or two.

I felt compelled to respond to Mr. Feldblum's post not necessarily to defend Microsoft, but because I have very similar conversations with people all the time about adopting new technology in general. There is a natural human reaction when something new and revolutionary is laid before them. They need to strike a balance between all the new possibilities this new technology offers with the tangible business value of replacing what they already have in place. In this case, the question is, "What do I gain from paying a development team to replace the considerable Flash presence on my sites with Silverlight?"

To assume that a project team with any company would simply throw out a project plan already in motion, ramp their developers and designers in a new technology and start over for the simple fact that there is a new way of accomplishing their goal is ridiculous. You wouldn't do that and I wouldn't do that, unless there was a real ROI as a result.

However, when I talk to people about adopting Silverlight, they always make the comment, "I already have so much Flash built into my web site, I don't know where to start with Silverlight." Well, the good news is you don't have to throw out the baby with the bath water. The fact of the matter is that you can begin to implement Silverlight where it makes sense in your web site without modifying or removing any of the Flash assets you already have in place. Silverlight will run just fine in a web page with Flash, so you can iteratively begin the process if implementing Silverlight and, if prudent, replacing Flash to take advantage of XAML, developer/designer collaboration, developing in managed code and all the other benefits Silverlight has to offer. No expensive and painful "big bang" replacement is necessary. Find a requirement for which Silverlight is a good fit and implement it. It's as simple as that.

The truth is, while the rest of the world would hold Microsoft to a higher standard than any other company, at the end of the day Microsoft works very much like the IT shops you probably work in. Each Microsoft product and web site has a team of developers and product managers that have a finite budget, timeline and resource pool in which to work. Believe me, if Silverlight could be deployed as a replacement to Flash across all Microsoft web sites next week, it would certainly make my job a hell of a lot easier, but that's not possible and difficult decisions have to be made in order to deliver a multitude of solutions currently underway on time and on budget.

I can all but guarantee you that there are roadmaps in place to adopt Silverlight across most or all of the Microsoft web assets. That adoption will be rolled-out in a manner that delivers value to the business and as it makes sense. You're seeing that adoption begin on Microsoft.com and MSDN, and should see it on more Microsoft sites in the coming months and years, a very timely example being the new Expression Suite web site, all built in Silverlight.

In fact, if you're still of the mindset that Microsoft isn't using Silverlight because they don't believe in it, it will probably interest you to know that NBC will be broadcasting all 17 days and 34 sports of the 2008 Summer Olympic Games this year, at total of 2,200 hours of streaming HD video with multiple views and control gadgets, all in Silverlight. For an early review, have a look at Adam Kinney's post.

Rather than shame Microsoft for not dropping everything else that they're working on to replace Flash with Silverlight, we should learn from their example of implementing Silverlight iteratively as it makes sense. That just good project management and good business.
