Workflow

The team tailored summary templates and prompts to probation meetings. Officers reviewed and edited each AI summary before it entered the case record. Regional implementation teams, video tutorials and on-site support backed the national rollout.

Relation to AI

The pilot relied on staff-reported time savings, and the hours saved are HMPPS estimates built from usage counts and an assumed saving per meeting. No controlled comparison isolates the effect of the tool.

Benefit marks

Depth

The number and color show the depth of a benefit.

  1. Depth 1. A convenience, or time or money saved.
  2. Depth 2. A measurable improvement in a result or ability.
  3. Depth 3. A lasting change, an ability restored, or a risk removed.

Beneficiary

  • Circle: a person
  • Square: an organization
  • Triangle: society

Evidence

  • Solid. A court or regulator found a benefit, or researchers independently studied it.

  • Hatched. Independent reporting.

  • Outline. Claimed by the parties. Only the people or organizations involved, or sources whose independence has not been assessed, support the benefit.

The fill changes with the evidence. The depth color stays the same.
