The government should really set a deadline for dealing with the backlog. For example, it could decide that all backlogs have to be cleared within six months and hire the resources needed to administer the process.
At the moment, resources are assigned to processing new files. However, applications and the backlog are not always being dealt with, and 20% of applications are not being processed within the prescribed time periods. We have no idea what's going on.
There should therefore be very clear direction from the government requiring all backlogs to be processed within something like six months. After that, there should be an accountability requirement if the deadline is not met.
