Thinking about the research design

I've been thinking about my research methods and research tools.
Till now, I still have questions on how exactly I plan to conduct the study.
But here's what I scribbled while thinking and rethinking about my research design.

Research Method:

CASE STUDY

1. INTERVIEWS (Informant Interview, Narrative Int., and Focus-Group Interview)

2. OBSERVATIONS (Observer as participant, complete participant, participant as observer)

OTHER SOURCES OF DATA:

2. Power Point slides from COMELEC-Angeles City
