The basic idea behind iterative enhancement is to develop a software system incrementally, allowing the developer to take advantage of what was being learned during the development of earlier, incremental, deliverable versions of the system.
Iterative Enhancement was successfully applied to the development of an extendable family of compilers for a family of programming languages on a variety of hardware architectures.
One major difference between iterative enhancement and the current agile development methods is the analysis and measurement activities as drivers in the iterative enhancement process.

  What is iterative development? -- Part 1: The developer perspective
And while it is true that these "development" activities embody many of the best practices recommended by the proponents of iterative development (such as test first, test often, etc.), the way that their application was described would result in a very tight iteration, the duration of which could often be measured in minutes.
In contrast to the individual developer, the leader of the development team is concerned with the coordination and optimization of the work of several developers, each of whom is changing or implementing a number of components that must be integrated into a release that fulfills the team's shared objectives.
To many developers, iterative and incremental development is the progression through an almost infinite series of iterations, each of which causes the system to grow larger and larger until the customers are happy with it or decide to stop investing in its further development.

 Development Methodology - MindGenies| a specialist in Internet applications
Managing complex software development projects is about efficient utilization of resources, risk management, accurate estimation of budgets and timelines, experienced selection of appropriate technologies, and scheduling feature development to meet time-to-market requirements.
Our orientation is towards Client-driven Iterative and Incremental Development model which implies that the choice of features for the next iteration comes from the client-whatever they perceive as the highest business value to them.
In modern iterative methods, the recommended length of an iteration is between one and six weeks.

 What is iterative development?
If the adoption of iterative and incremental development has no impact upon the business, and the way that it realizes the benefits provided by the iteratively developed solution, then its adoption becomes just a technical assurance issue and is of little consequence outside the development team itself.
One of the basic assertions behind all iterative and incremental software development processes is that the only thing that matters is the delivery of a solution; anything that does not contribute to the delivery of a solution is superfluous and needs to be eradicated.
This appears to be a more iterative and incremental approach, but it still leaves the requirements and development teams working in different managerial silos with all of the communication overhead and conflict that this can entail.

 Iterative vs. waterfall software development: Why don't companies get it?
Both of these practices fit very well in an iterative development cycle, provide some discipline without slowing the iterations, but provide for a more stable product that can be improved and will lengthen the life span of the software.
However, when we are developing a new product or a new software system, the fundamental thing we are doing is discovering what needs to be in the system in order to delight the customer.
[1] The iterative and incremental approaches involve a number of short cycles in which steps such as requirements gathering, coding, testing and deployment, are conducted to produce small parts of the final project.

 IT Development - SDM Handbook - Iterative Development - Liberty University
It is quite possible that a development team could take those phases and take a waterfall approach to development (that is, a strict sequencing of phases that is focused on fully completing each phase before moving on to the next).
This has the benefits of iterative development, without all the overhead and the "fuzzy front end" delays of Envisioning.
In modern iterative methods, the recommended length of one iteration is between one and six weeks.

 From The Trench, Dojo Toolkit, Cyclomatic Complexity » Blog Archive » Iterative Development and The Leaning ...
I think iterative and incremental development makes sense to manage large projects and is a good thing, but I also believe the way it is applied sometimes has a tendency to produce the Leaning Tower of Pisa.
As each subsystem was being developed that team created and evolved their own domain model (database model) derived from their interface to other subsystems and their functional scope.
This was somewhat addressed by retrofitting a system level domain model in the second increment of the project but the project suffered throughout because the domain model was considered less important as compared to the exposed functionality expressed as use cases.

 AGILE IN ACTION: Iterative and incremental development
the increment may require other software, that will only be developed in the next iteration, for it to be usable by the end-user.
An increment is simply an incarnation of the user story functionality at a point in time.
Agile software development employs both iterative and incremental development techniques but also applies feedback across releases or increments, or to use Extreme Programming terminology, iterations.

Iterative and evolutionary development is a foundation not only of modern software methods, but—as the history section of the "Evidence" chapter shows—of methods used as far back as the 1960s.
Iterative development is an approach to building software (or anything) in which the overall lifecycle is composed of several iterations in sequence.
Some older process literature [Wong84] used the term “incremental development" to mean a combination of frozen up-front specifications followed by iterative development of the features, but there is no widespread agreement on usage.

 (ootips) Iterative Incremental Development of Global Infrastructure
Yet incremental development organized along use cases is recommended and apparently very successful.
Whether you develop the infrastructure before the use cases, or whether you stub the infrastructure so that you can develop the use cases depends upon a number of factors.
You do some architecture and some stubbing and some skeleton code and some minimum feature support, and there is increment 2 (increment 1 is a "hello, partner" or "echo" type of program that shows that the global pieces can at least talk to each other).

 Overview of the Unified Process > Iterative and Incremental   (Site not responding. Last check: )
Building the architecture in an iterative and incremental fashion enables the team to make necessary major changes early in the process at considerably less cost than they would inflict later in the project.
By continually integrating new increments, the development team is also able to isolate problems that it might bring to the system and address those problems in ways that don't disrupt the integrity of the working system.
Perhaps the most important advantage that iterative and incremental development, as defined by the Unified Process, brings to the table is the project team's ability to focus its efforts on addressing the most critical risks early in the life cycle.

This is important for IID because the whole point of IID is that you don't have a comprehensive design at the beginning, you grow the design and the code together.
The leaders of the OO world pushed IID right from the beginning, which is why it's no surprise that the leaders of the agile movement almost entirely are OO people.
All this doesn't mean that objects and IID are mutually necessary, but I think it does indicate why the two have such a strong affinity.

A "RUP-based" Development Case is an instance of the RUP (and the UP), a configured or tailored subset of the RUP content (which may possibly be further augmented) that addresses the breadth and depth of the UP framework.
An iteration is iterative in that it is repetitive and involves work and rework, incremental in that it is additive and involves more than rework alone, and parallel in that work may be concurrent within the iteration.
Development cycles and phases may also be time-boxed; as development cycles, phases, and iterations are planned, the further the plans are in the future, the less accurate the estimates.

Larman and Vasili's article is packed with great examples of how IID (which is essentially the same as Agile programming) has been successfully used for decades on large scale mission critical projects.
The article goes on to list numerous projects and researchers who have successfully used Iterative and Incremental Development over the years.
Yet, even though the value of IID is well known among literate, experienced software engineers, some commercial organizations, consulting companies, and standards bodies still promote a document-driven single-pass sequential life cycle as the ideal.
