Proto-personas resemble personas but are not validated by months of costly research studies. They are personas created out of the necessity to begin working on a product immediately, without spending too much time on research. These personas are built on assumptions and the knowledge of the team and stakeholders. During the project, the proto-persona can be updated more accurately to reflect the user based on what we have learned throughout the process.

Prototypes make it possible to build interactions between the different mock-ups in order to simulate real use. They are particularly useful for conducting user tests.

The PHP Standard Recommendations (PSRs) are recommendations aimed at improving interoperability between PHP Frameworks. There are several recommendations that have been validated including PSR-4 which focuses on auto-loading classes and which has been adopted by Drupal 8. PSR-4 describes a specification for automatic loading classes of file paths. The autoload allows you to include files without the use of "include" statements, based on the namespace path.
