Eine Möglichkeit wäre:
\documentclass[tikz,border=2mm]{standalone}
\usetikzlibrary{positioning, shapes}
\begin{document}
\begin{tikzpicture}[
myarrow/.style={
signal, signal from=west, draw, fill=#1,
minimum height=1cm, minimum width=2cm,
node distance=2mm
},
legendarrow/.style={
node distance=#1,auto=left,->,>=stealth
}
]
\node[myarrow=yellow!30](a){plan};
\node[myarrow=green!30, right=of a](b){code};
\node[myarrow=cyan!30, right=of b](c){build};
\node[myarrow=red!30, right=of c](d){test};
\node[myarrow=blue!30, right=of d](e){release};
\node[myarrow=orange!30, right=of e](f){deploy};
\node[myarrow=brown!30, right=of f](g){operate};
\draw[legendarrow=1cm]
coordinate[below=of a](temp)
(temp) -- (temp-|c)
node[midway]{Beschriftung}
;
\end{tikzpicture}
\end{document}
