We will strive to follow best practices for software development, in particular for the PLCs. The policies included here will help us to improve the operations in a deliberate and well-considered manner, moving the control software from stable point to stable point.
In general as much as possible the development should be broken down into manageable pieces that can be implemented and tested separately. This helps to make the changes easier to develop and review, and gives us progress checkpoints to which we can roll back if needed.
