All right. It is called task in some books and some software packages.

It is time and resource consuming. This statement is important. Why is it important? Because a little later we're going to introduce something called lag. A lag is a period of time. So, it's like an activity but doesn't consume resources. It does consume time, no resources. You're waiting for something, you're not doing work, time is ticking. So, it is an activity. The lag is an activity, but we want to differentiate it from the activity that consumes resources.

However, there are guidelines into how big or small each activity. We need to have reasonable activity size. So, since we're using the day as a unit of time measure, don't make the activity as fractions of a day, like couple hours. Don't make it too long, like a month and a half or two months.
