Intervention Logic

• What is it? - Pathfinder definition• Why is it needed? – Benefits: ongoing and

one-off• How do you do it? – Forms• Success factors• Show me one! – Examples: LTSA and

Corrections• So what - Summary


What is it? - Pathfinder definition• “…an evidence-based, systematic and reasoned description of the links

between outcomes and outputs. It helps management relate their organisational activities to agency outcomes, and confirm their business approach is sound.”

• Part of a process that “…enables management to systematically prioritise outputs to maximise departmental outcomes,

• “…is a powerful tool that can inform many areas of management decision-making and planning.”

BB2, paras 6 and 13.


Why is it needed? – Ongoing benefits• Identifying interventions that maximise agency outcomes • Prioritising agency outputs and interventions • Monitoring agency performance towards outcome goals• Testing of intervention logic assumptions and hypotheses• Communicating departmental effectiveness


Why is it needed? – One-off benefits• Interagency collaboration: identifying needs and

collobaration with other agencies • Reviewing departmental activities and structure • Strategic and business planning • Identifying risks to outcome goals and targets • Identifying external influences upon agency and end

outcome(s)• Communicating and justifying agency activities and

proposed changes


How do you do it? – Forms

• Narrative - written description.• “Cause and effect” models• “Results chains” – box and arrow flow diagrams• Frameworks – matrices or tables – see Funnell• Disciplined Logic and Assumption Testing – inclusion of

IF/THEN to reveal underlying assumptions• Blended Intervention Logic – combination of one or more

of above


Success factors1. Clearly defined outcome(s)

2. The ‘vital few’

3. Research and evidence based

4. Simplicity

5. Outcomes not processes

6. Logical

7. “Top down”


“Cause and effect” model: LTSA“promoting safety in land transport at reasonable cost”

So what? - Summary

• Start with a well defined outcome• An integral part of strategic planning process and

internal and external communication• Facilitates interagency collaboration, output

prioritisation, and business process design and structures

• Ongoing benefits obtained when used with impact measures


Dimensions of Recidivism Index (State Indicator)

• Reconviction based on a single event• Time to Reconviction = 12 and 24 months• Seriousness = reconviction to a Department

Managed Sentence and Imprisonment

• For Offences committed post release• Aggregated into Services, age, ethnic,

gender, offence and sentence length groups
