  — This is great for other companies to be inspired — Leadership Principles We use our Leadership Principles every day, whether we’re discussing ideas for new projects or deciding on the best approach to solving a problem.

4 Principles are guiding this methodology - Readability - Quality Assurance - Logic - Reusable code 1 — Readability PSR-2 code styling Function no longer than 50 lines PHP doc Block TypeHint your functions Details: For better code readability we suggest PSR-2 code styling to be applied We consider a function bigger than 25 lines is not an efficient function. For engaging this methodology we recommend 50 lines maximum per function. DocBloc are essentials. Swagger in a case of API writing is essential to be present. A developer should be able to explain his work easily and quickly and should use materials to do so 2 — Quality Insurance No PHP error message No PHP Warning messages No PHP Notices No hardcore credentials Unit Testing Details: When executing the code we expect the quality assurance team to verify that no PHP errors, warnings, notices are produced. We also expect the QA team to go throughout the code to verify that no hardcore credentials are present within the code. Unit Te...
