需要帮助设计组织结构图

Question

我有一张想要重现的绘图，但我仍然无法很好地排列节点并使其正确居中。有人能帮我解决这个排列问题吗？这是我想要重现的绘图：

\documentclass[10pt,a4paper,oneside]{book}
\usepackage{tikz}
\usetikzlibrary{calc}

\begin{document}\begin{flushleft}

    \begin{tikzpicture}
\tikzset{every node/.style=
    {thick, draw=black, align=center, minimum height=50pt, text width=50pt}
}
\node(a1) {SALE};% start with left second level
\node[right=10pt] (a2) at (a1.east) {FINANCE};
\node[right=10pt] (a3) at (a2.east){WARE-\\HOUSE};
\node[right=10pt] (a4) at (a3.east) {M-PESA};
\node[right=10pt] (a5) at (a4.east) {EBU};
\node[right=10pt] (a6) at (a5.east) {MARKETING};
\node[right=10pt] (a7) at (a6.east) {OPERATION};
\node[right=10pt] (a8) at (a7.east) {CORPS SHOP\\VODASHOP};
\node[above=10pt] (top) at ($(a2.north)!.5!(a3.north)$) {Directeur de\\region};
%\node[below=20pt] (chini) at (top.north) {text};
\node[below=10pt] (b2) at (a2.south) {SALES};
\node[below=10pt] (b3) at (a3.south) {text};
\node[below=10pt] (b4) at (a4.south) {text};
\coordinate (atop) at ($(top.south) + (0,-5pt)$);% midpoint below top
%\coordinate (atop) at ($(top.north) + (0,-5pt)$);% midpoint below chini
\coordinate (btop) at ($(a3.south) + (0,-5pt)$);% midoint below a3
\draw[thick] (top.south) -- (atop)
%(chini.north) |- (atop) -| (a8.north)
(a1.north) |- (atop) -| (a8.north)
(a2.north) |- (atop) -| (a3.north)
(a3.south) -- (b3.north)
(b2.north) |- (btop) -| (b4.north);
\end{tikzpicture}
\end{flushleft}
\end{document}`

Answer 1

作为@SebGlav 答案的补充：

\documentclass[border=3.141592]{standalone}
\usepackage[edges]{forest}
\usetikzlibrary{positioning}
    \tikzset{
node distance = 4mm and 0mm,
     N/.style = {draw, thick, rounded corners=3pt,
                 inner sep=10pt}
            }

\begin{document}
    \begin{forest}
for tree={
% nodes styles
    N,
if level={1}{fill=cyan!30}{fill=red!30},
% tree style
    edge = {draw, thick},
    anchor=north,
    forked edge,
    s sep=4mm,
    l sep=24mm,
    fork sep=18mm,
    },
% tree body
[Directeur de région, name=DR
    [SALES]
    [FINANCE]
    [WAREHOUSE]
    [M-PESA]
    [EBU]
    [MARKETING]
    [OPERATION]
    [COPS SHOPS]
]
\node (RH)  [N, fill=red!30,
             below right=of DR] {RESSOURCES HUMAINES};
\draw[thick] (DR |- RH) -- (RH);
    \end{forest}
\end{document}

\documentclass[border=3.14mm]{standalone}

编辑：Plain Ti钾Z 解决方案，无任何包装

trees这是一个没有森林、没有图书馆、没有的解决方案chains，如果你只能做简单的 Ti钾现在的 Z 命令：

\documentclass[tikz,border=3.14mm]{standalone}
\usetikzlibrary{positioning,fit}
\tikzset{
        every node/.style={ draw,black,thick,
                            rounded corners=3pt,
                            minimum height=30pt,
                            inner sep=10pt,},
        chief/.style = {fill=cyan},
        sub/.style = {fill=pink},
        }     
\begin{document}
    \begin{tikzpicture}[node distance=5mm]
        \node[sub](1){SALES};
        \foreach \content [count=\i from 1] in {
            FINANCE,
            WAREHOUSE,
            M-PESA,
            EBU,
            MARKETING,
            OPERATION,
            COPS SHOPS}
            {
            \pgfmathtruncatemacro\j{\i+1}
            \node[sub,right=of \i](\j){\content};
            }
        \node[fit=(1)(8),draw=none](ens){};
        \node[above=3cm of ens,chief](DR){DIRECTEUR DE RÉGION};
        \draw[thick] (DR) --++ (0,-3) coordinate (aux);     
        \foreach \i in {1,...,8} \draw[thick] (aux) -| (\i);
        \draw[thick] (DR) |-++ (2,-1.5) node[sub,right]{RESSOURCES HUMAINES};
    \end{tikzpicture}
\end{document}
