Premises of Reinventing Government
  • What gets measured gets done.
  • If you don't measure results, you can't tell
    success from failure.
  • If you can't see success, you can't reward it.
  • If you can't reward success, you're probably
    rewarding failure.
  • If you can't see success, you can't learn from
    it.
  • If you can't recognize failure, you can't correct
    it.
  • If you can demonstrate success, you can win
    public support.

Osborne and Gaebler (1992 chapter 5,
"Results-Oriented Government")

Engage Stakeholders
Ensure Use and Share Lessons Learned
Describe the Program
Standards Utility Feasibility Propriety
Accuracy
Focus the Evaluation Design
Justify Conclusions
Gather Credible Evidence
7
Step 1 Engage Stakeholders
  • Fostering input, participation, and power-sharing
    among those persons who have an investment
  • Those involved in program operations
  • Those served or affected by the program
  • Primary users of the evaluation

8
Step 2 Describing the Program
Scrutinizing the features of the program being
evaluated, including its purpose and place in a
larger context.
  • Need
  • Expected effects
  • Activities
  • Resources
  • Stage of development
  • Context
  • Logic model

Step 4 Gathering Credible Evidence
  • Compiling information that stakeholders perceive
    as trustworthy and relevant for answering their
    questions.
  • Indicators
  • Sources of evidence
  • Quality of information
  • Quantity of evidence
  • Logistics

17
Step 5 Justifying Conclusions
  • Making claims regarding the program that are
    warranted on the basis of the data.
  • Stakeholder standards
  • Analysis and synthesis of findings
  • Interpretation of the facts
  • Judgments
  • Recommendations

18
Step 6 Ensuring Use and Sharing Lessons
Learned
  • Ensuring that stakeholders are aware, findings
    are used in decisions, and participants have a
    beneficial experience.
  • Designed for use
  • Preparation for findings
  • Feedback from all parties
  • Follow-up of users
  • Dissemination process
  • Additional Uses

23
What is the Intervention?
We are generally asked to evaluate an outcome of
an undefined program having unspecified
objectives on an often vaguely delineated
recipient group whose level or variety of
pathology is virtually impossible to assess,
either before or after their exposure to the
program.
  • Bloom, 1968. The evaluation of primary prevention
    programs in Greenfield and Miller, Comprehensive
    Mental Health The Challenge of Evaluation,
