The waterfall model is a relatively linear sequential design approach for certain areas of engineering design. In software development, it tends to be among the less iterative and flexible approaches, as progress flows in largely one direction through the phases of conception, initiation, analysis, design, construction, testing, deployment and maintenance.
The Rational Unified Process (RUP) is an iterative software development process framework created by the Rational Software Corporation, a division of IBM since 2003. RUP is not a single concrete prescriptive process, but rather an adaptable process framework, intended to be tailored by the development organizations and software project teams that will select the elements of the process that are appropriate for their needs. RUP is a specific implementation of the Unified Process.
Software development is the process of conceiving, specifying, designing, programming, documenting, testing, and bug fixing involved in creating and maintaining applications, frameworks, or other software components. Software development is a process of writing and maintaining the source code, but in a broader sense, it includes all that is involved between the conception of the desired software through to the final manifestation of the software, sometimes in a planned and structured process. Therefore, software development may include research, new development, prototyping, modification, reuse, re-engineering, maintenance, or any other activities that result in software products.
Craig Larman (1958) is a Canadian-born computer scientist, author, and organizational development consultant. With Bas Vodde, he is best known for formulating LeSS, and for several books on product and software development.
Lean software development is a translation of lean manufacturing principles and practices to the software development domain. Adapted from the Toyota Production System, it is emerging with the support of a pro-lean subculture within the Agile community. Lean offers a solid conceptual framework, values and principles, as well as good practices, derived from experience, that support agile organizations.
The incremental build model is a method of software development where the product is designed, implemented and tested incrementally until the product is finished. It involves both development and maintenance. The product is defined as finished when it satisfies all of its requirements. This model combines the elements of the waterfall model with the iterative philosophy of prototyping.
A product manager is a professional role which is responsible for the development of products for an organization, known as the practice of product management. For both physical products and virtual ones such as software, product managers work to define the business strategy behind a product, as well as specifying its functional requirements.
CollabNet VersionOne is a software development and delivery solutions provider headquartered in Alpharetta, GA. CollabNet VersionOne products and services belong to the industry categories of value stream management, devops, agile management, application lifecycle management (ALM), and enterprise version control. Products of these types are used by companies and government organizations to reduce the time it takes to create and release software.
Scrum is an agile framework for managing knowledge work, with an emphasis on software development. It is designed for teams of three to nine members, who break their work into actions that can be completed within timeboxed iterations, called sprints, no longer than one month and most commonly two weeks, then track progress and re-plan in 15-minute time-boxed stand-up meetings, called daily scrums.
James A. Highsmith III is an American software engineer and author of books in the field of software development methodology. He is the creator of Adaptive Software Development, described in his 1999 book "Adaptive Software Development", and winner of the 2000 Jolt Award, and the Stevens Award in 2005. Highsmith was one of the 17 original signatories of the Agile Manifesto, the founding document for agile software development.
Software quality management (SQM) is a management process that aims to develop and manage the quality of software in such a way so as the best ensure the product meets the quality standards expected by the customer while also meeting any necessary regulatory and developer requirements, if any. Software quality managers require software to be tested before it is released to the market, and they do this using a cyclical process-based quality assessment in order to reveal and fix bugs before release. Their job is not only to ensure their software is in good shape for the consumer but also to encourage a culture of quality throughout the enterprise.
Agile testing is a software testing practice that follows the principles of agile software development. Agile testing involves all members of a cross-functional agile team, with special expertise contributed by testers, to ensure delivering the business value desired by the customer at frequent intervals, working at a sustainable pace. Specification by example is used to capture examples of desired and undesired behavior and guide coding.
Of all the agile software development methodologies, outside–in software development takes a different approach to optimizing the software development process. Unlike other approaches, outside–in development focuses on satisfying the needs of stakeholders. The underlying theory is that to create successful software, the team must have a clear understanding of the goals and motivations of the stakeholders. The ultimate goal is to produce software that is highly consumable and meets or exceeds the needs of the intended client.
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. 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.
DevOpsis a set of software development practices that combines software development (Dev) and information technology operations (Ops) to shorten the systems development life cycle while delivering features, fixes, and updates frequently in close alignment with business objectives.
Specification by example (SBE) is a collaborative approach to defining requirements and business-oriented functional tests for software products based on capturing and illustrating requirements using realistic examples instead of abstract statements. It is applied in the context of agile software development methods, in particular behavior-driven development. This approach is particularly successful for managing requirements and functional tests on large-scale projects of significant domain and organisational complexity.
Disciplined agile delivery (DAD) is a process decision framework that enables simplified process decisions around incremental and iterative solution delivery. DAD builds on the many practices espoused by advocates of agile software development, including Scrum, agile modeling, lean software development, and others.
Agile usability engineering is a method created from a combination of agile software development and usability engineering practices. Agile usability engineering attempts to apply the principles of rapid and iterative development to the field of user interface design.
The Scaled Agile Framework, is a set of organization and workflow patterns intended to guide enterprises in scaling lean and agile practices. Along with large-scale Scrum (LeSS), disciplined agile delivery (DAD), and Nexus, SAFe is one of a growing number of frameworks that seek to address the problems encountered when scaling beyond a single team. SAFe is made freely available by Scaled Agile, Inc., which retains the copyrights and registered trademarks.
