List of software anti-patterns

Anti-patterns are commonly used ways of doing software engineering that are not useful or cause more issues than they solve. See design patterns for the opposite. There are many diverse types of software anti-patterns. Some relate to software design, object-oriented programming, computer programming, methodological, configuration management, DevOps, and other aspects of software engineering. Several books have popularized the idea and teaching of anti-patterns.^[1][2]

Anti-patterns can be found in anything that has organization, from project management to cultures,^[3] but this list focuses solely on software and computer science anti-patterns.

Generic software design anti-patterns

• Abstraction inversion – Computer programming anti-pattern
• Ambiguous viewpoint – Lack of clarity during software design
• Big ball of mud – Software source code with poor structurePages displaying short descriptions of redirect targets

• Inner-platform effect – Tendency of software architects to replicate their development platform
• Input kludge – Type of failure in software
• Interface bloat – Overload of elements on an interface
