Summary	A logic model is a diagram that lays out the intended logic of a program — how its resources and activities are expected to produce outputs and, through them, short-, intermediate-, and long-term outcomes. Popularized in human services by the W. K. Kellogg Foundation's development guide, it makes a program's underlying theory of change explicit and testable, providing the backbone for program planning, communication with stakeholders, and evaluation by clarifying exactly what the program does and what it is supposed to achieve.	A community needs assessment is a systematic process for identifying, documenting, and prioritizing the unmet needs of a community or population in order to plan programs, allocate resources, and justify funding. It draws on multiple kinds of evidence — statistical indicators, what people say they need, the services they actually seek, and comparisons with other areas — and a guiding typology, such as Jonathan Bradshaw's four types of social need, helps assessors recognize that 'need' is not a single, self-evident quantity but a judgment that depends on whose definition and which standard is applied.
