Software is Harder than it Looks

Last night, I was thinking about the game Words with Friends for the iPhone. I haven’t played, but I know a lot of people who love it. It’s basically an online version of Scrabble with a twist. I think the maximum time a player can take to finish a turn is a whole week. Games take a while to finish. Most of the people I know who play are participating in a handful of games at once. The genius of this game, and what makes it perfect for mobile devices like the iPhone, is that you can play it on your own time. On the bus and have a few minutes? No problem … that’s the perfect time to play your turn.

On the surface, this game seems super simple. “It’s basically Scrabble but online.” The concept sounds so easy and obvious that the implementation is taken for granted. People don’t understand how complex it is because it just works.

I don’t have any first hand knowledge of the game, but as simple and obvious as it seems, the implementation is likely a lot more difficult than that. Aside from the actual app that you download from the App Store, there is a whole infrastructure running to make sure games and players are kept in sync. Again, I don’t know the folks who built it but I’ll bet they spent a lot of time and effort making it work as well as it does. And I’ll bet they are constantly working on it, making it better and keeping it running smoothly.

Another example is an application I did work on: The TWCableTV application for the iPad. This application also seems simple. The first version just streams live video. That’s it. Since the first release, we’ve added Remote DVR and other features, but the vast majority of the time it’s used to simply watch TV.

What might be surprising is only a small handful (3-4) of people actually worked on the app that gets installed on the iPad. At least 7-10 people worked on the services that talk directly to the iPad, a bunch more to test the app, yet another 2-3 on making sure the television streams were setup and continue to function properly, a whole host of people working in our data centers to keep the lights on, and lots and lots of previous work by other teams across the company creating ways to programmatically retrieve things like a billing data and validate usernames / passwords. Add a few lawyers in the mix to keep us from violating our contractual agreements and the number of folks who had a hand in the application, directly or indirectly, is at least 50 and likely more in the realm of a hundred.

That’s a lot of people for an application that just plays TV.

My point is that ideas for software are comparatively easy to come up with. The implementation of ideas is the hard part. We definitely weren’t the first to think “it would be cool to let people watch live TV on an iPad”. However, we were the first to implement it. And it was hard.

Software is usually like that.

Often, when a person I just met learns I worked on an iPad application, they’ll say something like “I have a great idea for an iPad application that [insert great idea here]” That’s similar to saying “I have a great idea for a skateboard that hovers or a device that converts matter to energy, transports it, and then converts it back to matter”.

The amazing thing about the titans of the computer industry is not that they had great ideas but that they actually implemented the ideas. Steve Jobs didn’t just think of the iPhone. He built it. He hired the talented team of engineers, designers, testers, and even lawyers to make it all work.

It takes work. It takes tenacity. It’s, well … just like everything else great in life I suppose.

It’s hard.
