A software development process is a structure imposed on the development of a software product. Synonyms include software life cycle and software process . There are several models for such processes, each describing approaches to a variety of tasks or activities that take place during the process.
3.2 Agile software development
A largely growing body of software development organizations implement process methodologies. Many of them are in the defense industry , which in the U.S. requires a rating based on ' process models ' to obtain contracts.
The activities of the software development process represented in the waterfall model . There are several other models to represent this process.
Software testing is an integral and important part of the software development process. This part of the process ensures that bugs are recognized as early as possible.
[ edit ] Agile software development
Agile software development processes are built on the foundation of iterative development. To that foundation they add a lighter, more people-centric viewpoint than traditional approaches. Agile processes use feedback, rather than planning, as their primary control mechanism. The feedback is driven by regular tests and releases of the evolving software.
ISO 15504 , also known as Software Process Improvement Capability Determination (SPICE), is a "framework for the assessment of software processes". This standard is aimed at setting out a clear model for process comparison. SPICE is used much like CMMI. It models processes to manage, control, guide and monitor software development. This model is then used to measure what a development organization or project team actually does during software development. This information is analyzed to identify weaknesses and drive improvement. It also identifies strengths that can be continued or integrated into common practice for that organization or team.
Six Sigma is a methodology to manage process variations that uses data and statistical analysis to measure and improve a company's operational performance . It works by identifying and eliminating defects in manufacturing and service-related processes. The maximum permissible defects is 3.4 per one million opportunities. However, Six Sigma is manufacturing-oriented and needs further research on its relevance to software development.
Formalization of software development is creeping in, in other places, with the application of Object Constraint Language (and specializations such as Java Modeling Language ) and especially with Model-driven architecture allowing execution of designs, if not specifications.
Another emerging trend in software development is to write a specification in some form of logic (usually a variation of FOL), and then to directly execute the logic as though it were a program. The OWL language, based on Description Logic, is an example. There is also work on mapping some version of English (or another natural language) automatically to and from logic, and executing the logic directly. Examples are Attempto Controlled English , and Internet Business Logic, which does not seek to control the vocabulary or syntax. A feature of systems that support bidirectional English-logic mapping and direct execution of the logic is that they can be made to explain their results, in English, at the business or scientific level.
J2EE: EJB, JSP, Servlets, JSF, JSTL, JCA, JMS, JTA, JNDI, JDBC, JMX, RMI, etc.
Frameworks: Struts, Hibernate, JPA, iBATIS, JBoss AOP, Spring, JSF, AJAX, GWT, YUI, Flex/Flash, JUnit, and Jakarta common libraries.
Integration: Web Services on Axis and WebMethods; as well as the Web Service Standards such as SOAP, WSDL and UDDI.

The international standard for describing the method of selecting, implementing and monitoring the life cycle for software is ISO 12207 .
A decades-long goal has been to find repeatable, predictable processes that improve productivity and quality. Some try to systematize or formalize the seemingly unruly task of writing software. Others apply project management techniques to writing software. Without project management, software projects can easily be delivered late or over budget. With large numbers of software projects not meeting their expectations in terms of functionality, cost, or delivery schedule, effective project management appears to be lacking.
Organizations may create a Software Engineering Process Group (SEPG), which is the focal point for process improvement. Composed of line practitioners who have varied skills, the group is at the center of the collaborative effort of everyone in the organization who is involved with software engineering process improvement.
