What requirements?
I’m sure you’ll all be excited when I reveal that my husband gave me a humidifier for Christmas. It’s not a sexy gift, but I was genuinely happy to get it (my static-laden cats were happier than me– in theory, at least). The humidifier is lovely – tall and thin, and fits subtly into any room. It keeps the upper floor of our house nicely humidified (to the cats’ delight), and only goes through a tank of water per day. Despite all these wonderful features, I discovered a huge usability flaw the first time I went to fill the tank.
It has a lovely handle on top, as you can see:

But when I removed the tank to fill it, my user experience became a lot less delightful. The bottom handle is actually the lid to the opening for filling:

When I remove the lid to fill the tank, where do I grip it? Instead of a convenient handle to hold while I fill the tank, I’m left with a few less-than-ideal options. I can hold it by the water-delivery stem, and pray that it won’t get wet and slip – or become overly stressed by the weight and snap off. I can set it in the bathtub to fill, resulting in a great deal of overspray (to the cats’ dismay). Or I can hold it by the lip of the opening (which is kind of sharp). I generally opt for the later, resulting in less mess than option 2 and less danger than option 1. (That’s not entirely true - I generally opt to have my husband fill it, but that really is how he holds the tank.)

Perhaps the humidifier’s designers believed all their users would set this tall tank in kitchen sinks to fill. Nice idea, but I’d have to carry the tank downstairs every day to fill it. And like most consumers, I’m inherently lazy; an extra trip down the stairs every day isn’t appealing. That leaves me to choose between a deep bathtub and a shallow bathroom sink.
Grumble.
So aside from being irritated daily, what can I take away from this humidifier lesson? Requirements.
If a project team doesn’t fully flesh out requirements in the early stages of a project, and doesn’t keep revisiting requirements as the project progresses, that team will end up with an unfillable humidifier.
Or an unusable website.
When starting a project, it’s imperative to take the time to fully consider requirements. Most project teams are eager to get a project rolling – to jump right in and start seeing results. That’s great; we all love results. More importantly, though, we love successful results. Without fully identifying the objectives, scope, and end users, any project’s risk of failing to meet the project’s goals skyrockets. The impact of missed requirements can be huge, and that impact only increases as the project moves through its lifecycle.
That’s why it’s key to hold a team kickoff meeting. To document objectives, scope, personas, and site architecture. To review every deliverable with the team. And to test the product with end users. Because without knowing requirements, how can any project team accurately build any product for anyone?

Great connection; point well illustrated!Suzi May 10, 2009
Maybe they expect you to use another container, like an empty milk jug, to fill the tank and just take the tank out for cleaning? That, of course, did not meet YOUR expectations.
