Hofman’s Law

"The time to complete an IT project is proportional to the amount of time already spent on it."

or sometimes

"The time to complete an IT project is the same as the amount of time already spent on it."

I have been using this law for a long time when trying to help large scale SW development projects that are stuck. Discussing the implications and reality of this law helps to break a deadlock, even though the law is meant humorous.

What do you think?
