Intuition

I was told by one of our users today, “This feature is very straightforward, very logical and intuitive one…”.

What I felt he meant was a nicer way of saying: “Use common sense and you’ll know la…”. Yet we know we don’t understand enough about that feature.

In reality, common sense isn’t so common after all. I mean, what I think is common sense, is based on my experience and what I think everyone should know. However, that is so not true. It is related to one’s experience and culture, and how he/she see things.

This common sense problem becomes more problematic when dealing with user requirements. The user feels that the requirements are complete, because the omitted details are so logical, sensible, and can be automatically and “inituitively” interpreted by anyone. And so he may choose not to go into the level of detail necessary to save time and saliva. That assumption may lead to incorrect implementation, due to domain ignorance of the developers, especially if they don’t make an effort to clarify the requirements.

Of course it’s unlikely you’ll get totally complete and totally unambiguous requirements, but you should try to understand as much as possible. On one extreme is believing there’s such thing as a “complete requirements”, and the other end is believing there’s no such thing so we can ignore requirements gathering.

Better be shot during requirements stage than to be strangled after development when the product don’t meet user expectations. The cost of change would be too high then.
