A one-page delivery and security scorecard: checklist for one service

A checklist for building a one-page scorecard for a single service, with the five DORA delivery metrics and four security measures, plus review rules.

A useful scorecard fits on one page, covers one service, and shows the five DORA delivery metrics beside four security measures over the same weeks. Build it with the checklist below, and agree on definitions and owners before anyone looks at a number.

Before you start

  • One service chosen, with a named owner
  • A time window agreed, such as the last 12 weeks
  • A person from engineering and a person from security assigned
  • Agreement that the page is for conversation, not ranking

DORA's guide says the metrics are best used for one application or service at a time, and warns against competition between teams. Both points shape this checklist.

Delivery section: five rows

RowDefinition to write down
Change lead timeStart: committed to version control. End: deployed in production
Deployment frequencyCount of production deployments per week
Failed deployment recovery timeTime to recover from a deployment needing immediate intervention
Change fail rateShare of deployments needing immediate intervention
Deployment rework rateShare of unplanned deployments caused by a production incident

Checklist for this section:

  • Each definition written in one sentence and shared
  • "Immediate intervention" defined, for example rollback or hotfix
  • "Unplanned" defined
  • Median and worst case shown for time-based rows

Security section: four rows

RowDefinition to write down
Time to remediateIdentified to fix deployed, by severity
Scan coverageShare of the service's repos and images scanned in the window
Open exploitable findingsFindings with a known exploit or reachable path
Gate outcomesPassed, blocked and overridden pull requests

Checklist for this section:

  • Severity scale stated, and the source of severity named
  • Coverage denominator defined, such as repos on the service inventory
  • Exploitable defined, and who decides
  • Overrides include the approver and reason

Review rules

  • Read rows in pairs: lead time with overrides, frequency with fail rate
  • Look at trends over weeks, not a single week
  • Note small samples. A week with two deployments says little
  • Record one action per review, with an owner and date
  • Revisit definitions each quarter

What to leave out

Leave out any ranking of people, any figure with no named owner, and any number you cannot explain in one sentence. DORA warns against having one metric to rule them all, so the page should never lead with a single headline score.

After the first month

Ask what the page changed. If no decision followed from any row in a month, remove the row. If a decision was made with a missing number, add it. Over time the page should shrink to the rows people act on.

Quick check

How many services should we start with?

One. Extend to others after the definitions have held for a quarter.

Can the scorecard be automated?

Yes, once definitions are stable. Automate the data pulls, not the review conversation.
