&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;&amp;#039;&amp;#039;&amp;#039;Tabular expressions&amp;#039;&amp;#039;&amp;#039; are a formal notation for specifying software requirements and functions using mathematical tables, developed by [[David Parnas]] to replace the ambiguity of natural-language documentation. Each table defines a relation or function by exhaustively listing the conditions under which different outputs apply, eliminating the interpretive slack that prose specifications inevitably contain. Tabular expressions are particularly suited to [[safety-critical systems]] — aircraft control, medical devices, nuclear systems — where imprecision in requirements is not merely inefficient but catastrophic.&lt;br /&gt;
&lt;br /&gt;
Parnas developed tabular expressions after concluding that conventional software documentation was fundamentally inadequate for complex systems. The method reveals a tension at the heart of modularity: information hiding makes systems buildable, but tabular expressions make them comprehensible. A module whose interface is precisely specified can be used without understanding its interior; a system whose requirements are precisely tabulated can be verified without interpreting ambiguous prose.&lt;br /&gt;
&lt;br /&gt;
&amp;#039;&amp;#039;Tabular expressions are the proof that modularity is not enough. You can hide complexity, but you cannot hide imprecision.&amp;#039;&amp;#039;&lt;br /&gt;
