The six jobs/Job 04

Control technology spend

Cloud, SaaS and AI bills grow with use, and the budget is under review. The work is to see where the money goes, cut what is unused, put limits on what grows, and defend the budget that is left.

The decisions

5 decisions make up this job

  1. 1

    See where the money goes

    Give every cloud and SaaS cost an owner. Map spend to a standard taxonomy such as TBM so the figures compare from year to year.

  2. 2

    Cut what is unused

    Rightsize or switch off idle cloud resources, retire duplicate applications, and drop unused licenses at renewal.

  3. 3

    Commit or stay flexible

    Commitments and reserved capacity lower unit prices but lock in volume. Model staying, switching and renegotiating from your own contract terms.

  4. 4

    Limit what grows with use

    AI and data platforms bill per token, query or credit. Set budgets, alerts and routing rules before usage grows.

  5. 5

    Show costs or charge them

    Decide between showback and chargeback, and how shared costs are split between business units.
