==Cost-Benefit Modelling of End User Development==
According to one analysis, EUD essentially out-sources development effort to the end user. Because there is always some effort to learn an EUD tool motivation depends on users' confidence that it will empower their work, save time on the job and/or raise productivity. In this model the benefits to users are initially based on marketing, demonstrations and word-of-mouth. Once the technology is put into use experience of actual benefits becomes the key motivator.<ref>{{cite journal

This study defines costs as the sum of:
*Technical cost: the price of the technology and the effort to install it
*Learning cost: the time taken to understand the technology
*Development cost: the effort to develop applications using the technology
*Test and debugging cost: the time taken to verify the system.
The first and second costs are incurred once during acquisition, whereas the third and fourth are incured every time an application is developed. Benefits (which may be perceived or actual) are seen as:
* Functionality delivered by the technology
* Flexibility to respond to new requirements
* Usability of applications produced
* Overall quality of the applications produced.
