# Shotgun Surgery

> Making any modifications requires that you make many small changes to many different classes.

## Signs and Symptoms

Making any modifications requires that you make many small changes to many different classes.

## Reasons for the Problem

A single responsibility has been split up among a large number of classes. This can happen after overzealous application of [Divergent Change](/smells/divergent-change).

## Payoff

* Better organization.
* Less code duplication.
* Easier maintenance.
