Defining success: stakeholder satisfaction.
Objective data and expertise can point to the need for specific outcomes obtained by specific means. Ultimately, however, a policy or infrastructure project is judged to be ‘successful’ when it meets the felt needs of the community and affected stakeholders, or mitigates or resolves what they feel to be a problem. It is about meeting expectations and generating satisfaction. Success is about what the people think and feel.
Challenges arise when objectives are fragmented. As between the stakeholders. And as between the project proposer and the people affected by the project. Problems may be exacerbated by constrained budgets and time-frames.
