need a translation help about a programming diagram

[patrice]

Hi Joe,
I knew the general word "Flowchart", it is even often used in France. I also know a less general name which is "Directed Tree", but it is still too general.

I am looking for the name of this particular Flowchart (or very close to) which specific to structured programming. This way of doing the flowchart of a program is linked to an analyze method.
As the flowchart is build incrementally, the method guide you to draw the next refinement until the tree is detailed enough to program the solution.
Details may vary in the drawing of the tree, but the tree represent the algorithm use to solve a problem.
