In agile software development, what is the difference between iterative and incremental development? Are they the same thing? What is the distinction between these two words? From Wikipedia :. Iterative development was created as a response to inefficiencies and problems found in the waterfall. The basic idea behind this method is to develop a system through repeated cycles iterative and in smaller portions at a time incremental , allowing software developers to take advantage of what was learned during the development of earlier parts or versions of the system.
A software development process, also known as a software development lifecycle, is a structure imposed on the development of a software product. A software process is represented as a set of work phases that is applied to design and build a software product. There is no ideal software process, and many organisations have developed their own approach to software development. Software development processes should make a maximum use of the capabilities of the people in an organisation and the specific characteristics of the systems that are being developed [ 1 ] [ 14 ] [ 15 ]. Software specification. In this activity the functionality of the software and constraints on its operation must be defined.
In software engineering , a software development process is the process of dividing software development work into distinct phases to improve design , product management , and project management. It is also known as a software development life cycle SDLC. The methodology may include the pre-definition of specific deliverables and artifacts that are created and completed by a project team to develop or maintain an application. Most modern development processes can be vaguely described as agile. Other methodologies include waterfall , prototyping , iterative and incremental development , spiral development , rapid application development , and extreme programming. A life-cycle "model" is sometimes considered a more general term for a category of methodologies and a software development "process" a more specific term to refer to a specific process chosen by a specific organization. The field is often considered a subset of the systems development life cycle.
The iterative process starts with requirements or assumptions that form the base of the project. In essence, you create the first product, test it, and revise for the next version. The iterative process is simply a series of steps that you repeat, tweaking and improving your product with each cycle. In practical terms, think of it as practice to make your product perfect.

The combination of the two approaches: iterative and incremental has been long-standing and has been widely suggested for large development efforts. Through repeated cycles iterative and smaller and simpler portions of the software to be developed at a time incremental , allowing software developers to take advantage of what was learned during the development of earlier parts or versions of the system. Learning comes from both the development and use of the system, where possible key steps in the process start with a simple implementation of a subset of the system requirements and iteratively enhance the evolving larger or more complex versions until the full system is implemented. At each iteration, design modifications are made and new functional capabilities are added.
