Through partnership working with key stakeholders, increasing the capacity to promote and protect the health needs of a population, and reducing the level of unmet need and health inequalities. (Cavanagh and Chadwick 2005)

(Cavanagh and Chadwick, 2005) The assessment is supported by local and national government priorities which encourage local authorities, groups and individuals to establish which services are required to meet these needs, therefore implementing strategies that are needed by communities to prevent ill-health. Through Healthy Lives Healthy People (2010) the government promotes the move of power to local government and communities, enabling them to tackle local problems and increase their health and well-being.
