	Teens and Tweens: Spiral curricula (Site not responding. Last check: 2007-10-08)
		Spiral curricula, conceived by psychologist Jerome Bruner, allow for a broad range of topics to be taught in the early grades.
		Spiral curricula for math offer some problems, and might better be replaced by mastery curricula with a little more focus, and a little more responsibility returned to the teacher.
		The spiral model, when abused, looks eerily like the teaching of old that leaves topics disconnected and disjointed, only this teaching is even worse, because it discourages memorization--the only thread by which some children are hanging who do not master understanding first.

	Spiral model - Wikipedia, the free encyclopedia
		The spiral model is a software development process combining elements of both design and prototyping-in-stages, in an effort to combine advantages of top-down and bottom-up concepts.
		This model was not the first model to discuss iterative development, but it was the first model to explain why the iteration matters.
		For a typical shrink-wrap application, the spiral model might mean that you have a rough-cut of user elements (without the polished / pretty graphics) as an operable application, add features in phases, and, at some point, add the final graphics.

	Spiral Model
		However, the spiral model is not as sophisticated and elaborate as some of the other lifecycle models.
		The spiral model, which has only been evolving for a couple of years, is based on the use of the application of the waterfall model to government software projects.
		The risk-driven nature of the spiral model is more adaptable to the plethora of software project situations than the document-driven lifecycles such as the waterfall model or the primarily code-driven lifecycles such as evolutionary prototype.

	Domain Model of Evolutionary Spiral Process Model
		Given a domain model of an application domain, an individual target system (one of the members of the family) is created by tailoring the domain model given the requirements of the individual system.
		The spiral model domain model is tailored according to a particular project's process drivers to generate a specific process model for that project.
		The domain model of the spiral model is described together with the risk-related process drivers, the CMM level 2 and level 3 process drivers.

		The model is best suited when: A set of high quality, stable user requirements exist and The user require the complete system all at once and Previous experience of building similar systems exist and The duration of the project is two years or less.
		Spiral Model The essential concept of spiral model is to minimize risks by the repeated use of prototypes and other means.
		Conclusion Each software development organization should decide on a life-cycle model that is appropriate for that organization, its management, its employees, and its software process, and vary the model depending on the features of the specific product currently under development base on their strengths and minimizing their weaknesses..

	STSC CrossTalk - The Spiral Model as a Tool for Evolutionary Acquisition - May 2001
		Under the spiral model the answers to these questions are driven by risk considerations and vary from project to project and sometimes from one spiral cycle to the next.
		A major difficulty of the original spiral model was its lack of intermediate milestones to serve as commitment points and progress checkpoints.
		A valuable aspect of the spiral model is its ability to support incremental commitment of corporate resources rather than requiring a large outlay of resources to the project before its success prospects are well understood.

	Spiral Dynamics
		Spirals are a dynamic expression of natural and cosmic forces, a "dominant universal fractal" evident in everything from our DNA code to the spiraling galaxies that inhabit the universe.
		Transmitting the genuinely inclusive or "integral" perspective that is the essence of the Spiral Dynamics model, Beck portrays the vast tapestry of global cultures with the care, insight, and easy familiarity with which one might speak about the members of one’s extended family, each with their unique capacities and challenges.
		As cofounder of the National Values Center in Denton, Texas, and President and CEO of the Spiral Dynamics Group, Inc., a global enterprise, he is, by his own definition, a "Spiral Wizard," employing the Spiral Dynamics model to effect large-scale systems change in and among various sectors and societies of the world.

	Spiral Development Workshop, February, 2000, Final Report (Site not responding. Last check: 2007-10-08)
		Spiral development is a family of software development processes characterized by repeatedly iterating a set of elemental development processes and managing risk so it is actively being reduced.
		This report also shows how the spiral model can be used for a more cost-effective incremental commitment of funds, via an analogy of the spiral model to stud poker.
		Some practiced or proposed process models appear to be spiral, but violate one or more of the invariants.

	SpiralModel
		In this model the software is developed in a series of incremental releases with the early stages being either paper models or prototypes.
		The spiral model is a realistic approach to the development of large-scale software products because the software evolves as the process progresses.

	Adaptive Web-Based Learning for Students with Diverse Backgrounds: Case Study in a Introductory Programming Language ...
		The objectives of the spiral model are to support exploration of the subject matter based on competency, personal preference, interest and background to any depth without requiring the instructor to define explicit navigational paths.
		The spiral model supports desire to know by providing convenient navigational paths in any subject matter or skill from a given level of competence to a higher level one.
		A full implementation of the spiral model is planned for the fall 1998 semester and a web-based course will be offered as an alternative to the traditional lecture version of the second programming course (also being offered that semester).

	A brief explanation of the Therapeutic Spiral Model
		The Therapeutic Spiral Model maximizes the effectiveness of psychodrama while helping the clinician stabilize the client in a safe structure built of prescriptive roles for containment, restoration and observation.
		Because the Therapeutic Spiral Model is self-renewing, culturally specific, and taught and practiced by members of the community for that community, it has the power to promote change globally even as it adapts to each locality.
		Because it is not limited to one person, organization or country, the Therapeutic Spiral Model has the power to free people from repeated cycles of violence and help them find a place of greater healing, hope and possibility.

	Untitled Document
		The Waterfall Model is a natural fit for contract-based software development since this model is document driven; that is, many of the products such as the requirements specification and the design are documents.
		Thus, the Spiral Model addresses the problem of requirements engineering through development of prototypes, and it addresses the need for risk management by performing risk analysis at each step of the life cycle.
		In either case, the spiral gets started by a hypothesis that a particular operational mission could be improved by a software effort." Thus maintenance simply becomes another spiral or phase in the life cycle of the software.

		My contribution to this problem was to show that the accublation model itself generates spirals without the need for other processes except for conduction of heat within the ice cap.
		The basic equations I used to explain the spirals have also been used to model spiral shapes that arise in other fields including biology (bacteria growth in a petri dish) and chemistry (reaction-diffusion equations).
		In the Geology paper, the spirals merged from an initially-random distribution of sublimation, but cracks on Mars probably originated near the edge of the ice cap.

	A brief introduction to the Therapeutic Spiral Model (Site not responding. Last check: 2007-10-08)
		The Therapeutic Spiral Model was developed by clinical psychologist Kate Hudgins, Ph.D., TEP, as an integration of classical psychodrama, object relations and recent advances in trauma treatment to provide additional safety and structure when working with trauma.
		It features a chapter on the model as well as other chapters from 17 psychodramatists from around the world explaining how they have used psychodrama to address trauma of all kinds, including family abuse, political torture, rape, traffic accidents, significant loss and war.
		The model has been adapted for use by diverse clinicians around the world in working with treatment of eating disordered people, sex offenders and addicts and alcoholics in various stages of recovery.

		In the Therapeutic Spiral Model, strengths are identified as personal qualities (intrapsychic), interpersonal (supportive relationships), and transpersonal (a connection with a spiritual force).
		As the role, or identity, of "The Addict" is being reduced, the Therapeutic Spiral Model provides a set of additional new behaviors, which are called "roles" in the philosophy of the psychodramatic method.
		Because the Therapeutic Spiral Model is self-renewing and taught and practiced by members of the community for that community, it has the power to promote change globally even as it adapts to each locality.

	Colors of Thinking in Spiral Dynamics
		Through decades of research, Dr. Graves built "the emergent, cyclical, double-helix model of adult biopsychosocial systems development." (When asked about the ponderous title once during a conference, he responded with, "Well, dammit, that's what it is" and a wink.) He used pairs of letters to designate the interaction of conditions-without and latent systems-within.
		Another tributary of Spiral Dynamics is the burgeoning science of memetics which describes the notion of memes -- idea/information packets that transfer virus-like from mind to mind, community to community.
		Graves' model is open-ended, so new letters, numbers, or colors will need to be added as new levels of psychological existence are identified in human nature.

	Extreme Programming Is Just The Spiral Model
		I would say that "spiral" (incremental development, with increasing system scope in each increment) is simply the minimum required of any project that intends to succeed.
		Spiral in my recollection (not even sure where my copy of the original Boehm (wasn't it?) article is) is an iterative risk-first development model.
		Spiral is what I was apparently doing before I knew it had a name.

	The Neume Notation Editor -- Spiral Model of Software Development
		The main advantage of the spiral model over traditional development models (such as the waterfall model [3]) is that it is "risk-driven." That is to say, the risks of design flaws, improper tools, mismatch with user needs, and so on, are detected early in the development process.
		This author has found that the spiral model can produce surprisingly good results, especially when the application to be programmed is not fully understood.
		He has, however, had less success with the spiral model for maintenance tasks on existing software.

	Chaos model - Wikipedia, the free encyclopedia
		In computing, the Chaos model is a structure of software development that extends the spiral model and waterfall model.
		The chaos model was defined by (the pseudonymous) L.B.S. Raccoon.

	STSC CrossTalk - Balancing Discipline and Flexibility With the Spiral Model and MBASE - Dec 2001
		We also describe and rationalize the major MBASE extensions to the spiral model (model clash avoidance, stakeholder win-win), and elaborate on the use of these extensions and risk considerations in the anchor-point milestones used in MBASE and the spiral model.
		Further, none of the approaches were compatible with the project's success model of producing an initial operational capability in 36 months; or with an additional property model, which was being adopted by the organization.
		In a subsequent spiral cycle, the next-level stakeholders would include representative users of the e-commerce system, and the reconciliation of their win conditions would include prototyping of the user interface to eliminate the risk of showing up at COMDEX with an unfriendly user interface.

	WinWinSpiralModel
		This is an adaptation of the spiral model which emphasis is explicitly placed on the involvement of the client in a negotiation process at the genesis of the product development.
		To achieve this objective the model defines a set of negotiation activities at the beginning of each pass around the spiral.
		In addition to the early emphasis placed on the win-win condition, the model also introduces three process milestones (anchor points), which help establish the completion of one cycle around the spiral and provide the decision milestones before the software project proceeds.

	Win-Win Spiral
		The Win-Win Spiral Model proposed by Barry Boehm is a new take on a traditional software process.
		While maintaining many of the traditional elements of the spiral model, the Win-Win version strives to involve all stakeholders in the development process.
		Traditional practices, such as requirements engineering, design, code, and test, are still present during each iteration of the spiral, but the collaborative step throughout the development process makes it distinctly adaptive.

	Spiral Development Model (Site not responding. Last check: 2007-10-08)
		In this model, development is a cyclical cooperative effort with scheduled prototypes used to clarify and confirm the correctness of the product.
		Note that at the start of every cycle, the client and developer get together to evaluate the progress of the project and negotiate what needs to be included in the next cycle.
		The model is based on a description in Software Engineering: A Practitioner's Approach, 4th edition, Roger S. Pressman, Ph.D., McGraw-Hill, New York, 1997, ISBN 0-07-114603-2, pp39-41.
