Every neighborhood has some conditions, unique to itself, perhaps historical or political in nature, which cannot be anticipated beforehand by policymakers or policy implementers. These conditions represent potential roadblocks because they may conflict with certain aspects of policy implementation. Policies that are more flexible, and have more room to allow tailoring to local conditions are, therefore, more likely to succeed.
These examples from the preceding chapters illustrating the two themes--a small-wins approach, and flexibility--could easily be expanded. The reader may find it a helpful exercise to consider how the other chapters illustrate, or perhaps even contravene, these two themes.
These two themes demonstrate a larger point, raised in the Preface. They are instances of how research can inform policy. Research can point toward the parameters within which policy can be most effectively developed and implemented. Such guides may, initially, seem troublesome to those who develop policy. But, such an inconvenience will be quickly forgotten if the policies developed and implemented turn out to be highly effective.
