Conceptual models are iterative documents that evolve as the practice issue and/or the context changes.
The objective of this paper is to document the iterative procedure used to identify, select and prioritize user requirements.
Several studies document that iterative question formats used in contingent valuation studies produce anomalies in respondent behavior that appear to threaten the validity of welfare estimates.
Trustworthiness of the study was established using within-project evaluation and was accomplished by multiple methods of data collection (interviews and document analysis), iterative data analysis and coding, member checks of themes with several participants.
A draft summary of the findings was written by SM and commented on by NK and KM, and subsequently revised in an iterative way until the document represented an agreed understanding of the analytical findings.
Centralized Institutional Review Boards (New England Institutional Review Board in 2007 and Copernicus Group Independent Review Board from 2008 to 2011) approved the studies and iterative submission of study documents (study protocol, interview guides, patient information and informed consent form, and health information and demographic form).
Consensus was achieved by group discussion during conference calls and face-to-face meetings, as well as by iterative revisions of the written document.
The human computer interaction lessons from our iterative design process have been documented in Washington et al.43 We created robust facial expression software31,45,46 and implemented many design-focused iterations.32,47 The present study expands upon our previous work and sends our prototype system to the home environments of children with ASD.
During the readings, recurring themes were documented in an iterative process.
Table 1 traces this iterative conceptual model development process, documenting all revisions made between the protocol (Hollands 2014) and final versions, together with the rationale and supporting evidence for each revision.
Three of those mathematicians (co-authors here) also participated in iterative rounds of interviews designed to document and investigate their experiences as they worked to implement this curriculum.
