ArchitectureStructural problems such as a bridge built from both sides of a river that doesn't align in the middle. human error such as a dangerous product in packaging that looks like a food product.human scale such as a door that is too narrow for many people.human factors such as the use of hard brick on a jogging path that is likely to harm the health of joggers. full range of human characteristics and abilities such as an elevator that is unusable for many people with disabilities.edge cases such as an aircraft design that fails to consider severe storms that are rare but possible.sensory design such as a product that makes a beeping sound that many users find unpleasant.bliss point by giving the customer too much or too little. For example, a chocolate bar that is too small to be satisfying or too large such that customers regret eating it.user engagement such as a game that is perceived as boring.
StyleA product that lacks visual appeal such as a pair of shoes that fails to invoke the interests and passions of customers.visually balanced such that it is perceived as low quality and unstable.color scheme that fails to communicate. For example, a blue life jacket that is difficult to spot in the water.arrangement of elements such as a navigational tool that customers perceive as disordered.
Information StructureThe structure of information such as a deep website based on sparsely populated categories that make information and tools difficult to discover.User interfaces that fail to communicate where things can be found. For example, cryptic icons based on abstract concepts that customers find nonintuitive.information density that is similar to a book and may become frustrated by sparse information or environments that pack too much into a screen.emerges as tightly packed buildings and narrow streets such that the future needs of the city are difficult to meet.
Errors & DefectsA design that doesn't work such as software that is buggy due to its design.design for failure. For example, a web browser that allows a poorly designed web page to crash it.reliability engineering such as a bridge in an earthquake prone area that can't endure a large earthquake.productive such as software that requires users to jump through dozens of hoops to complex a task that could be much simpler.per unit of output such as an inefficient engine that consumes more fuel and generates less useful energy than the competition.
WasteA design that is wasteful such as an over packaged snack. This can be viewed as a failure of sustainability.
Refinement & EloquenceRefinement and eloquence are commonly used to describe the artistic prowess of a design. In some cases, a design can follow all the rules of design and meet customer needs but still be a failure simply because it lacks refinement such that it is perceived as unattractive.
|Overview: Design Failure|
A design that is low value or that destroys value.
