Device Lifecycle Management (DLM):
The Complete Guide for IT Decision-Makers

1. What is Device Lifecycle Management?

Device Lifecycle Management (DLM) describes the holistic approach to managing the complete lifecycle of corporate mobile end devices. DLM differs from MDM in one important respect: MDM is the technical software solution for device management during active use. DLM is the overarching management concept that also covers procurement, logistics, physical configuration, repair, device disposal and cost control.

3. Why DLM is essential for businesses

Without continuous lifecycle management, device administration falls apart into many separate steps – spread across departments, service providers and spreadsheets. This is exactly where the typical problems originate:

• Hidden costs – procurement, support, repair and disposal are rarely viewed together. The true cost of a device stays invisible.
• Security and compliance gaps – devices with no clear status, un-wiped old devices and missing records are a GDPR risk.
• Burden on the IT department – every procurement, every replacement and every warranty case ties up internal capacity that is then missing for core work.
• No reliable overview – how many devices are in use, in what condition and with what remaining term, often cannot be answered.

DLM addresses exactly these points: it makes the entire device inventory transparent, standardises the processes across all phases, and shifts the operational effort to a specialised partner. An unmanageable catch-all topic becomes a controllable, predictable service.

4. DLM costs and ROI

The cost of DLM as a managed service is billed per device per month – how high it is depends on the number of devices, the depth of service and the contract term. What matters, however, is not the price alone but the overall calculation:

• Internal effort saved – procurement, support, repair and warranty handling tie up internal IT capacity that DLM frees up.
• Returns from used device buyback – functional devices are bought back at market-rate prices, reducing the net investment.
• Avoided follow-up costs – less damage thanks to protective equipment, less downtime thanks to the reserve pool, no compliance risks thanks to complete documentation.
• Predictability – instead of fluctuating individual costs, the result is a fixed, calculable monthly rate.

5. DLM as a managed service: what ETS takes care of

• MDM enrolment and personalised user assignment
• Ongoing monitoring, helpdesk and incident management
• Warranty and repair handling directly with manufacturers
• Device collection, buyback and certified data erasure

6. DLM and sustainability

A well-managed device lifecycle is not only economical but also makes ecological sense. The decisive lever lies at the end of the lifecycle: whether an old device becomes electronic waste or gets a second life depends on how structured the return process is.

DLM ensures a closed loop here:

• Reuse instead of disposal – functional devices are refurbished and remarketed after certified erasure, rather than being scrapped prematurely.
• Certified data erasure as a prerequisite – only the ISO-certified Blancco erasure certificate makes reuse possible in a data-protection-compliant way.
• Audit-proof destruction – only what is genuinely no longer usable is destroyed in accordance with DIN 66399 and recycled in an environmentally sound manner.
• Longer service life – a reserve pool and professional repair handling keep devices in use longer and avoid premature new purchases.

In this way, Device Lifecycle Management contributes directly to a company's sustainability goals – with less electronic waste, lower resource consumption and a verifiable, documented approach to old devices.
