Beamer with Tikzpicture – How to Change Scale of Picture and Distance Between Lines of Nodes

scalingtikz-pgf

I am a beginner in LaTeX, trying to convert a presentation in beamer. I am experiencing difficulties with the scale option that does not seem to work, and I cound not find a way to reduce slightly the space between text lines in the nodes of the tikz picture 

\documentclass[xcolor=dvipsnames, smaller]{beamer}
\usepackage[utf8]{inputenc}
\usepackage{times}
\usepackage{tikz}
\usetikzlibrary{chains, positioning}
\setbeamertemplate{navigation symbols}{} 
\mode<presentation> {
 \usetheme{Warsaw}
% \usetheme{default}
}

\title{\textcolor{white}{Test slide}} %Normal title
\author{}
\date{}
\begin{document}
\section{First section}
\section{Second section}
\section{Third section}
\section{Fourth section}
\section{Sixth section}

\begin{frame}[fragile]{Extremely long title for this particular slide, further elongated to serve as example}
\alert {Include all value -added and non value-added steps (Process steps, inspection/test, rework, scrap, delay\dots)}\\

\begin{tikzpicture}[scale=0.8, %does not seem to work

Best Answer

When you use scale, consider using transform shape as well, so that the transformation (here: scaling) is applied, via option to node or to the whole picture. For example:

\begin{tikzpicture}[scale=.8, transform shape, ...
