The document discusses various frameworks and methodologies for theoretical and conceptual frameworks in research, including:
1) Nunamaker's multi-methodological approach to IS research which combines observation, theory building, systems development, and experimentation.
2) The software engineering research methodology which has three phases - conceptual, formal, and developmental.
3) The DAGS framework which integrates design science, action research, grounded theory, and system development methodologies.
4) Grounded theory which is an inductive methodology that allows theories to emerge from data through constant comparison and theoretical sampling.
