สรุป	Field-based program evaluation is an applied research method that assesses the implementation, outcomes, and value of a program by collecting data directly in the natural setting where the program operates. Rather than relying solely on administrative records or remote surveys, evaluators embed themselves in the field — observing activities, interviewing stakeholders on-site, and reviewing context-specific documents — to produce evidence-grounded judgments about program merit and worth.	Case study research is a qualitative research design that investigates a specific phenomenon, individual, group, organisation, or event in depth within its real-world context. Systematised by Robert K. Yin in 1984, it supports single-case and multiple-case designs and draws on multiple data sources — interviews, observation, documents, and artefacts — to build a rich, contextualised account of a bounded unit.
