• It is a method of qualitative analysis which is quite intensive and comprehensive.
• Its primary purpose is to explore the uniqueness of a singular case.
• The case could be a person, a classroom, an organization or a policy.
• It values multiple viewpoints of participants and observation in naturally occurring conditions.
• It involves conducting a systematic, in-depth inquiry of a subject and aims to add to the already existing knowledge about the subject.
• It preserves wholeness of the units i.e. it is an approach which views any social unit as a whole.
