I think there can be a marriage for both IL and CL that has not been discussed. The driver for IL is employee freedom without “Big Brother.” The IL model is usually associated with a Stipend Model, which may seem inexpensive and easy to predict but is it really? The cost to an enterprise to generate and monitor a Stipend Model can be expense, then don’t forget all the reasons why “My expense went up this month so I need to be reimbursed.” This creates a model that seemingly works but when you lift the hood can be extremely inefficient.
Then there is CL “Big Brother” you get what you get and you don’t complain. Not good for those that want the latest and greatest in technology and devices. Usually has the lowest cost but this needs to be managed, which requires resources.
In a perfect world there need to be a model for lowest cost with choice…. How would employees feel if the “Contract” was owned by the corporation but the employee had the freedom to choose their own device, features, functionality etc, the enterprise would pay a large % of the bill and the balance would be placed on the employees payroll as a deduction. This way the employee has “skin the in game.” Result is low cost of ownership for the corporation and employee choice, if the employee wants to lower their cost monthly they change how they use the device. The enterprise still benefits from security, control and low cost of ownership. This is a different model for MDM and or MEM.
