How i modify the last code in link (Work breakdown structure (WBS) TikZ), to make a WBS structure, like a image 
.
I don't know how to introduce a new level in wbs example.
Thanks!!!

A starting point:

Stefan Kottwitz has made some modifications to my code and has also added some real text to the nodes; the result can also be seen in texample.net:
\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{arrows,shapes,positioning,shadows,trees}
\tikzset{
basic/.style = {draw, text width=2cm, drop shadow, font=\sffamily, rectangle},
root/.style = {basic, rounded corners=2pt, thin, align=center,
fill=green!30},
level 2/.style = {basic, rounded corners=6pt, thin,align=center, fill=green!60,
text width=8em},
level 3/.style = {basic, thin, align=left, fill=pink!60, text width=6.5em}
}
\begin{document}
\begin{tikzpicture}[
level 1/.style={sibling distance=40mm},
edge from parent/.style={->,draw},
>=latex]

\node[root] {Drawing diagrams}
% The first level, as children of the initial tree
child {node[level 2] (c1) {Defining node and arrow styles}}
child {node[level 2] (c2) {Positioning the nodes}}
child {node[level 2] (c3) {Drawing arrows between nodes}};
% The second level, relatively positioned nodes
\begin{scope}[every node/.style={level 3}]
\node [below of = c1, xshift=15pt] (c11) {Setting shape};
\node [below of = c11] (c12) {Choosing color};
\node [below of = c12] (c13) {Adding shading};
\node [below of = c2, xshift=15pt] (c21) {Using a Matrix};
\node [below of = c21] (c22) {Relatively};
\node [below of = c22] (c23) {Absolutely};

\node [below of = c32] (c33) {Resizing tips};
\node [below of = c33] (c34) {Shortening};
\node [below of = c34] (c35) {Bending};
\end{scope}
% lines from each level 1 node to every one of its "children"
\foreach \value in {1,2,3}
\draw[->] (c1.195) |- (c1\value.west);

With stolen code from TeXexamples ... the following can serve as starting point for your effort to make desired tree:
Real text in nodes, and number of nodes should not be too difficult to change and add.
