As the previous section shows, there are many methodologies. The first challenge
faced by project managers is to select which methodology to use. Choosing a
methodology is not simple, because no one methodology is always best. (If it were,
we’d simply use it everywhere!) Many organizations have standards and policies to
guide the choice of methodology. You will find that organizations range from having
one “approved” methodology to having several methodology options to having
no formal policies at all.
