Deployment throughput in Ops Run It
Ops Run It teams vary between organisations. Your application support team could be called application operations. Your change management and application support teams could be augmented by a service introduction team, who assess operational readiness prior to live launch.
A delivery team performs automated functional testing and exploratory testing. When they want a production deployment to happen, they need to follow a service management process owned by the operations teams:
- 1.Delivery team requests change. The delivery team adds a ticket into the change management queue, in a workflow system such as ServiceNow. In ITIL v3, this is classified as a normal change request.
- 2.Change management team reviews change. When the change management team picks up the ticket, they approve or reject the change request in a Change Advisory Board (CAB) meeting, based on their knowledge of other in-flight changes.
- 3.Change management team requests deployment. If the change is approved, the change management team schedules a ticket into the application support queue.
- 5.Delivery team performs post-deployment validation. The delivery team does some post-deployment smoke testing, before the application support team accepts ownership of the new live service.
We've occasionally seen a deployment throughput variant of Ops Run It, in which delivery teams can perform some classes of deployments themselves. It requires a high degree of automated functional testing, and a fully automated deployment pipeline including change management approvals and production deployments. Change requests are pre-approved for small, regular changes. Large, irregular changes still require a CAB meeting and deployment by the application support team. In ITIL v3, this is the difference between standard and normal change requests.
This variant depends on a high trust environment, with a strong culture of collaboration. It's heavily dependent on senior leaders in Delivery and Operations functions sharing a sense of urgency, and teams working hard to recognise their similarities rather than their differences. We've only seen this work in a few mid-sized organisations, and we've not seen it scale to many teams.
Ops Run It deployment throughput costs are listed in Table 2. We've attributed to each an estimate of how much they usually contribute to the total cost of ownership. Per deployment costs are charged to operational expenditure (opex) rather than capital expenditure (capex), as the operations teams are centralised and distinct from any particular service.
Cost Type | Frequency | Description | Impact | TCO % |
|---|---|---|---|---|
Setup cost | One-off | Launch costs incurred in
| Capex cost | Low |
Opportunity cost | Per feature | Can be measured as the cost of delay between product feature readiness and its launch. Potential revenue loss, missed customer opportunities due to
| Lost revenue, capex or opex cost increase | High |
Run cost | Per deployment | Deployment costs incurred in
| Opex cost | Medium |
