The spiral model is a risk-driven software development process model. Based on the unique risk patterns of a given project, the spiral model guides a team to adopt elements of one or more process models, such as incremental , waterfall , or evolutionary prototyping .
John Ward Creswell is an American academician known for his work in mixed methods research. He has written numerous journal articles and 27 books on mixed methods research, research methods , and qualitative research .
The spiral approach is a technique often used in education where the initial focus of instruction is the basic facts of a subject, with further details being introduced as learning progresses. Throughout instruction, both the initial basic facts and the relationships to later details are repeatedly emphasized to help enter into long-term memory ...
Agile modeling (AM) is a methodology for modeling and documenting software systems based on best practices. It is a collection of values and principles that can be applied on an (agile) software development project. This methodology is more flexible than traditional modeling methods, making it a better fit in a fast-changing environment. [59]
Dynamic systems development method (DSDM) is an agile project delivery framework, initially used as a software development method. [ 1 ] [ 2 ] First released in 1994, DSDM originally sought to provide some discipline to the rapid application development (RAD) method. [ 3 ]
Spiral Dynamics describes how value systems and worldviews emerge from the interaction of "life conditions" and the mind's capacities. [8] The emphasis on life conditions as essential to the progression through value systems is unusual among similar theories, and leads to the view that no level is inherently positive or negative, but rather is a response to the local environment, social ...
Rapid application development (RAD), also called rapid application building (RAB), is both a general term for adaptive software development approaches, and the name for James Martin's method of rapid development. In general, RAD approaches to software development put less emphasis on planning and more emphasis on an adaptive process.
Multimethodology or multimethod research includes the use of more than one method of data collection or research in a research study or set of related studies.Mixed methods research is more specific in that it includes the mixing of qualitative and quantitative data, methods, methodologies, and/or paradigms in a research study or set of related studies.
