It was argued that PICO may be useful for every scientific endeavor even beyond clinical settings. [2] This proposal is based on a more abstract view of the PICO mnemonic, equating them with four components that is inherent to every single research, namely (1) research object; (2) application of a theory or method; (3) alternative theories or methods (or the null hypothesis); and (4) the ...
The PRISMA flow diagram, depicting the flow of information through the different phases of a systematic review. PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) is an evidence-based minimum set of items aimed at helping scientific authors to report a wide array of systematic reviews and meta-analyses, primarily used to assess the benefits and harms of a health care ...
As a preface to his analysis of methodologies used in health services research, Donabedian identified the three dimensions that can be utilized to assess quality of care (structure, process, and outcome) that would later become the core divisions of the Donabedian Model. [16] “Evaluating the Quality of Medical Care” became one of the most ...
Contextual inquiry (CI) is a user-centered design (UCD) research method, part of the contextual design methodology.A contextual inquiry interview is usually structured as an approximately two-hour, one-on-one interaction in which the researcher watches the user in the course of the user's normal activities and discusses those activities with the user.

A context model (or context modeling) defines how context data are structured and maintained (It plays a key role in supporting efficient context management). [1] It aims to produce a formal or semi-formal description of the context information that is present in a context-aware system. In other words, the context is the surrounding element for ...
When problem analysis is incorporated into the software development process, the software development lifecycle starts with the problem analyst, who studies the situation and: creates a context diagram; gathers a list of requirements and adds a requirements oval to the context diagram, creating a grand "all-in-one" problem diagram.
A concept map or conceptual diagram is a diagram that depicts suggested relationships between concepts. [1] Concept maps may be used by instructional designers , engineers , technical writers , and others to organize and structure knowledge .
