Do it yourself (DIY) is the method of building

modifying, or repairing things without the direct aid of experts or professionals.

Academic research describes DIY as behaviors where "individuals engage raw and semi-raw materials and component parts to produce, transform

or reconstruct material possessions,

including those drawn from the natural environment (e.g. landscaping)".

DIY behavior can be triggered by various motivations previously categorized as marketplace motivations (economic benefits, lack of product availability,

lack of product quality, need for customization), and identity enhancement

(craftsmanship, empowerment, community seeking, uniqueness).

The term "do-it-yourself" has been associated with consumers since at least 1912 primarily in the domain of home improvement and maintenance activities.

The phrase "do it yourself" had come into common usage (in standard English) by the 1950s,

in reference to the emergence of a trend of people undertaking home improvement and various other small craft and construction projects as both a creative-recreational and cost-saving activity.
