This document describes the Programming Methodology Framework also known under the PMF methodology. The methodology is based on the manifesto written by Zed A. Shaw which
|
||
describes a natural approach to software engineering with a strong focus on the act of programming. The PMF methodology uses a soft naming to allow for a non-partisan reference
|
||
to official engineering or project documents describing one of the most used software engineering methodologies.

The <span>[<a href="#THE-TAO-OF-PROGRAMMING" class="xref">THE-TAO-OF-PROGRAMMING</a>]</span> describes similar methodologies which strongly focus on coding, scripting and programming.<a href="#section-1-3" class="pilcrow">¶</a></p>
