The document was heavily based on experiential expertise. The research interviewed 22 people with psychosocial disabilities who had direct lived experience with NDIS individual funding packages. Participants shared their personal experiences of choice-making, barriers faced, and strategies used across all stages of the NDIS process. The study used grounded textual analysis to let categories emerge directly from participants' experiential accounts and perspectives.

The document incorporated some practice wisdom through its expert advisory group, which included practitioners from mental health organisations, universities, and advocacy bodies with professional experience in disability services. However, the primary focus was on lived experience rather than practice wisdom. The research methodology centred on participants' personal accounts, with professional expertise serving mainly in an advisory capacity to guide the research design and interpretation.

The document was based on research and evaluation insights. It employed rigorous qualitative research methodology including structured interviews with 22 NDIS participants, grounded textual analysis allowing themes to emerge from data, and systematic evaluation across multiple trial sites. The study analysed participants' experiences to identify barriers, enablers, and the "labour of choice" involved in NDIS processes, providing evidence-based findings and recommendations.
