Lifecycle

Acquisition, maintenance, replacement and disposal, planned rather than triggered by failure. The unplanned version is always more expensive.

The idea

How it works

Purchase price is usually a minority of what an asset costs over its life. Maintenance, licensing, energy, training and disposal make up the rest, and they arrive after the decision has been made.

Replacement planned in advance is cheaper than replacement triggered by failure, in every dimension except this quarter’s budget — which is why the second happens so often.

Working with it

In practice

  1. 01

    Cost the whole life at purchase

    Including maintenance, consumables, training and disposal. The comparison between options usually changes.

  2. 02

    Set expected life at acquisition

    A date written at purchase produces a planned replacement. One decided later produces an emergency.

  3. 03

    Plan replacement before failure

    Assets rarely fail without warning. The warning is usually ignored because acting on it costs money now.

  4. 04

    Include disposal

    Data, regulated materials and contractual obligations all make disposal more than a skip.

The components of lifecycle

A component is something that exists afterwards which did not exist before — a deliverable or a mechanism, not an intention.

  1. The lifecycle cost model

    Total cost of ownership per asset, including everything after purchase.

  2. The replacement schedule

    Expected end of life per asset, set at acquisition.

  3. The disposal procedure

    What happens at end of life, including data and regulatory obligations.

    Learn

Set the expected replacement date at purchase. A date decided later is decided during an outage.
