A company looking to upgrade its IT equipment often leaves its unused IT assets in storage for future use. This is either to serve as tech for new employees or as backup devices.
From experience, the entire logistics of managing, processing, and auditing can be overwhelming. It's why most companies leave this part of their business as an afterthought.
Old IT assets are primed for data breaches and they also depreciate in value every month it stays in storage.
This action can do more harm to your brand than good. The best thing to do upon making the decision to buy new tech is to plan for the disposal and remarketing of your old tech.
