Lessons learned from EUD solutions can significantly influence the software life cycles for commercial software products, in-house Intranet/Extranet developments and enterprise application deployments.
This study defines costs as the sum of:
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:
In response to this End User Software Engineering (EUSE) has been defined as a higher level of EUD, whereby end users become motivated to consider security and verifiability when developing their solutions.
All the above approaches assume that the user is developing software using tools already approved by a central IT function where "the user is naive, with little understanding of data processing.... but users should no longer be considered universally ignorant of information systems. Moreover, sophisticated information center veterans, as well as microcomputer users, can and do contribute to system development. They are capable of preliminary experimentation with system requirements, in particular those related to user interface." In this case the assumption is that the tools have a high learning curve and require exceptional expertise to be deployed in a secure, reliable and scalable manner.
An alternative scenario is that end users (and/or their consultants) employ declarative tools that support rigorous business and security rules at the expense of performance and scalability. Though this is a valid separation of concerns it can lead to a situation where Requirements analysis and prototyping are substantially completed and documented by end users before business analysts have considered the limitations of a specific Application or Software framework. Senior management support for such end user initiatives depends on their attitude to existing or potential Vendor lock-in.
