Quick Interview Answer

KISS means Keep It Simple. In software design, it encourages choosing the simplest solution that correctly satisfies the requirements and remains understandable.

Detailed Explanation

KISS means Keep It Simple. In software design, it encourages choosing the simplest solution that correctly satisfies the requirements and remains understandable.

Simplicity is not the same as minimizing the number of classes or lines. A few well-defined components may be simpler to maintain than one large class containing many unrelated responsibilities.

Code Example

// Prefer a direct solution until
// complexity or variation justifies
// another abstraction layer.
