express cost per business transaction and test how it changes with volume.

Planned topics

  • Unit cost, such as cost per order, links infrastructure to business value.
  • Split fixed costs (baseline) from variable costs (scale with volume).
  • Sensitivity: change one driver at a time (orders, page views, data volume) and see the effect.
  • Watch for steps and cliffs: a larger database tier, extra zones, new licence bands.
