What is the difference between inventory and asset management?

Inventory is tracking the physical existence of equipment (what we have and where). Asset management is the full lifecycle: purchase, depreciation, owner, EOL date, licenses, compliance. Asset management includes inventory but goes much further.

What is a CMDB and how does it connect to asset management?

A CMDB (Configuration Management Database) is the database of asset management - it contains all IT resources and their relationships. A laptop in the CMDB is linked to the user, installed software, the network, incident history and the warranty contract.

What benefits does full asset management bring?

Full asset management with a CMDB and lifecycle tracking reduces unnecessary purchases of equipment we already have, makes it easier to plan replacements at end of life (EOL), helps maintain license compliance and reduces the risk of audit penalties. The scale of savings depends on organization size and the previous level of inventory discipline.

Inventory vs asset management IT

Q: When is inventory enough and when do you need asset management?

Inventory is enough for companies under 50 employees with simple IT infrastructure. Asset management is essential at 200+ employees, multiple locations, compliance requirements (ISO, NIS2, SOC2) and the need to report financial depreciation.

Inventory: What do we have? Where is it? Asset Management: What we have, where it is, how much it costs, when to replace it, who has access.

Definition: Inventory vs Asset Management

Inventory:

"Do we have it?" - How many laptops do we have? How many monitors?
Physical existence - you count the equipment
Basic tracking - where it is (e.g. room 301)
No financial info - price, depreciation
No lifecycle - when bought, when to replace

Asset Management (IT resource management):

Full lifecycle - from purchase to disposal
Financial tracking - price, depreciation, TCO
Owner tracking - who has it, who has access
Warranty tracking - how long the warranty lasts, when it ends
Compliance - whether the equipment is licensed and meets security requirements
Planned replacement - when to replace (EOL planning)

When is inventory enough, and when do you need asset management?

Inventory is enough (SMB, under 50 people):

Small company, simple IT
Standard hardware (everyone has a Dell laptop, Lenovo monitor)
You do not need to track depreciation (taxes do not require it)
You do not have stringent compliance requirements

You need asset management (Enterprise, 200+ people, manufacturing, regulated):

Large organization with complexity
Multiple locations, multiple IT teams
Financial reporting - you have to know depreciation
Compliance (ISO, SOC2, NIS2) - asset tracking is mandatory
EOL planning - you plan a budget for equipment replacement

Asset management in practice - what do you track?

For each asset:

Asset ID (unique identifier)
Type (laptop, server, router)
Model and serial number
Purchase date and cost
Warranty end date
Owner (who has it)
Location
Depreciation schedule (3-5 years)
Status (active, in repair, retired)
License (software licenses tied to it)

CMDB - Configuration Management Database

A CMDB is an asset management database - it contains all IT resources and their relationships. A laptop is linked to:

User (owner)
OS and installed software (licenses)
Network (IP address, MAC)
Incident history
Warranty contract

The CMDB is the core of ManageEngine SDP (Enterprise edition). Asset lifecycle manager is a module in SDP.

Asset management metrics

KPI #1: Asset discovery % - do you know about all your assets? Target: 95%+.

KPI #2: Depreciation accuracy - is the book value (financial) accurate? Target: 98%+.

KPI #3: EOL planning - % of equipment that has less than 1 year to EOL and a planned replacement. Target: 80%+ planned.

KPI #4: License compliance - does the number of licenses match the installed software? Target: 100% compliance.

Quick decision: If you manage more than 100 pieces of equipment or you have to report depreciation - asset management. If under 50 pieces and simple IT - inventory is enough.
