- 3. End User In information technology, the term end user is used to distinguish the person for whom a hardware or software product is designed from the developers, installers, and servicers of the product. The "end" part of the term probably derives from the fact that most information technologies involve a chain of interconnected product components at the end of which is the "user."
- 4. Definition of End User Development End-user development (EUD) or end- user programming (EUP) refers to activities and tools that allow end-users – people who are not professional software developers – to program computers.
- 5. Artefacts end users may be objects describing some automated behaviour or control sequence, such as database requests or grammar rules, which can be described with programming paradigms such as programming by demonstration, programming with examples, visual programming, or macro generation. They can also be parameters that choose between alternative predefined behaviours of an application. end-user development may also refer to the creation of user-generated content such as annotations, which may be or not computationally interpretable (i.e. can be processed by associated automated functions).
- 6. Examples Examples of end-user development include the creation and modification of: 3D models created with end-user oriented tools and apps such as Sketchup. Game modifications to introduce users' own characters, environments, etc. — many recent games are distributed with modification in mind Web Mashups in the form of visual languages such as Yahoo! Pipes.
- 7. End User Development Cycle
- 8. Characteristics End user as the developer and maintainer.
- 9. Characteristics The developer is the client, therefore there are no communication issues
- 10. Characteristics Small budget and/or short time period for development
- 11. Advantages of End User Development Encourages active user participation Improves requirements determination Strengthens user sense of ownership Increases speed of systems development
- 12. Disadvantages of End User Development Inadequate expertise leads to underdeveloped systems Lack of organizational focus creates "privatized" system Insufficient analysis and design leads to subpar systems Lack of documentation of a system may lead to its being short lived
