BYOD is an IT policy allowing employees to use their personal devices for work, driven by user satisfaction, productivity, and cost savings. COPE involves providing devices and letting employees use them on and off the job, while CYOD provides approved devices with company-provided costs, offering a balance between BYOD and COPE models. Both BYOD and COPE offer benefits such as increased employee satisfaction, cost savings, and productivity, but also have their drawbacks.
