What is a project
One way of defining what is a project is to say any piece of work which is not regular. Not something you would do in your day to day role. That way any new piece of work can be thought of as a project.
Another way to define what a project is as follows:
It takes more than a day to complete.
It needs more than one person to complete.
You consider it to be complex.
The Tiger-Taming definition is:
Big Teeth – the work is complex.
Big Claws – the work has challenges which need planning.
Stripes – the work involves more than one person.
Long Tail – the work takes more than one day.
