In fact, we all manage a project in our everyday life. Take this simple example: inviting friends to dinner.
Someone in your family suggests the idea to invite the friends of the family for dinner. You think that it is a good idea. A day after, some questions begin to come into your mind: Who to invite? Who could help? What budget you can put on this? When doing that? Etc. Collectively, with your family members, you answer to those questions and confirm the idea.
