Determine what type* of project you have:
Quest - Know what but don’t know how
Fog - Don’t know what and don’t know how
Painting by Numbers - Know what and know how
Movie - Don’t know what but know how
It is always important to know what you do not know so you can add finding out this information as part of your plan. (This may mean adding another team member with the knowledge, getting training…..)
