Cowboy coding is software development where programmers have autonomy over the development process. This includes control of the project's schedule, languages, algorithms, tools, frameworks and coding style. Typically, little to no coordination exists with other developers or stakeholders.
A cowboy coder can be a lone developer or part of a group of developers working with minimal process or discipline. [1] Usually it occurs when there is little participation by business users, or fanned by management that controls only non-development aspects of the project, such as the broad targets, timelines, scope, and visuals (the "what", but not the "how").[ citation needed ]
"Cowboy coding" commonly sees usage as a derogatory term when contrasted with more structured software development methodologies.
In cowboy coding, the lack of formal software project management methodologies may be indicative (though not necessarily) of a project's small size or experimental nature. [2] Software projects with these attributes may exhibit:
Lack of estimation or implementation planning might cause a project to be delayed. Sudden deadlines or pushes to release software may encourage the use of "quick and dirty" techniques that will require further attention later. [3]
Cowboy coding can be common at the hobbyist or student level where developers might initially be unfamiliar with the technologies, such as testing, version control and/or build tools, usually more than just the basic coding a software project requires.
This can result in underestimating time required for learning, causing delays in the development process. Inexperience might also lead to disregard of accepted standards, making the project source difficult to read or causing conflicts between the semantics of the language constructs and the result of their output. [4]
Custom software applications, even when using a proven development cycle, can experience problems with the client concerning requirements. Cowboy coding can accentuate this problem by not scaling the requirements to a reasonable timeline, and might result in unused or unusable components being created before the project is finished. Similarly, projects with less tangible clients (often experimental projects, see independent game development) could begin with code and never a formal analysis of the design requirements. Lack of design analysis could lead to incorrect or insufficient technology choices, possibly requiring the developer to port or rewrite their software in order for the project to be completed.
Many software development models, such as Extreme Programming, use an incremental approach which stresses that the software must be releasable at the end of each iteration. Non-managed projects may have few unit tests or working iterations, leaving an incomplete project unusable. As such, agile methodologies have been compared to cowboy coding but agile has formal processes, procedures, measurement, project management and other oversight while cowboy coding has none of this.

The waterfall model is a breakdown of development activities into linear sequential phases, meaning they are passed down onto each other, where each phase depends on the deliverables of the previous one and corresponds to a specialization of tasks. The approach is typical 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 waterfall model is the earliest SDLC approach that was used in software development.
A software company is an organisation — owned either by the state or private — established for profit whose primary products are various forms of software, software technology, distribution, and software product development. They make up the software industry.
Rapid application development (RAD), also called rapid application building (RAB), is both a general term for adaptive software development approaches, and the name for James Martin's method of rapid development. In general, RAD approaches to software development put less emphasis on planning and more emphasis on an adaptive process. Prototypes are often used in addition to or sometimes even instead of design specifications.
Software development is the process used to conceive, specify, design, program, document, test, and bug fix in order to create and maintain applications, frameworks, or other software components. Software development involves writing and maintaining the source code, but in a broader sense, it includes all processes from the conception of the desired software through the final manifestation, typically in a planned and structured process often overlapping with software engineering. Software development also includes research, new development, prototyping, modification, reuse, re-engineering, maintenance, or any other activities that result in software products.
In systems engineering, information systems and software engineering, the systems development life cycle (SDLC), also referred to as the application development life cycle, is a process for planning, creating, testing, and deploying an information system. The SDLC concept applies to a range of hardware and software configurations, as a system can be composed of hardware only, software only, or a combination of both. There are usually six stages in this cycle: requirement analysis, design, development and testing, implementation, documentation, and evaluation.
In software development, agile practices include requirements, discovery and solutions improvement through the collaborative effort of self-organizing and cross-functional teams with their customer(s)/end user(s). Popularized in the 2001 Manifesto for Agile Software Development, these values and principles were derived from, and underpin, a broad range of software development frameworks, including Scrum and Kanban.
In agile principles, timeboxing allocates a maximum unit of time to an activity, called a timebox, within which a planned activity takes place. It is used by agile principles-based project management approaches and for personal time management.
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.
Open-source software development (OSSD) is the process by which open-source software, or similar software whose source code is publicly available, is developed by an open-source software project. These are software products available with its source code under an open-source license to study, change, and improve its design. Examples of some popular open-source software products are Mozilla Firefox, Google Chromium, Android, LibreOffice and the VLC media player.
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. According to the Project Management Institute, an incremental approach is an "adaptive development approach in which the deliverable is produced successively, adding functionality until the deliverable contains the necessary and sufficient capability to be considered complete."
Extreme programming (XP) is an agile software development methodology used to implement software systems. This article details the practices used in this methodology. Extreme programming has 12 practices, grouped into four areas, derived from the best practices of software engineering.
Coding best practices or programming best practices are a set of informal, sometimes personal, rules that many software developers, in computer programming follow to improve software quality. Many computer programs require being robust and reliable for long periods of time, so any rules need to facilitate both initial development and subsequent maintenance of source code by people other than the original authors.
Software requirements for a system are the description of what the system should do, the service or services that it provides and the constraints on its operation. The IEEE Standard Glossary of Software Engineering Terminology defines a requirement as:
In software engineering, a software development process or software development life cycle (SDLC) is a process of planning and managing software development. It typically involves dividing software development work into smaller, parallel, or sequential steps or sub-processes to improve design and/or product management. 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.
The INVEST mnemonic for Agile software development projects was created by Bill Wake as a reminder of the characteristics of a good quality Product Backlog Item or PBI for short. Such PBIs may be used in a Scrum backlog, Kanban board or XP project.
A programming team is a team of people who develop or maintain computer software. They may be organised in numerous ways, but the egoless programming team and chief programmer team have been common structures.
Agile Business Intelligence (BI) refers to the use of Agile software development for BI projects to reduce the time it takes for traditional BI to show value to the organization, and to help in quickly adapting to changing business needs. Agile BI enables the BI team and managers to make better business decisions, and to start doing this more quickly.
Extreme programming (XP) is a software development methodology intended to improve software quality and responsiveness to changing customer requirements. As a type of agile software development, it advocates frequent releases in short development cycles, intended to improve productivity and introduce checkpoints at which new customer requirements can be adopted.
Evolutionary database design involves incremental improvements to the database schema so that it can be continuously updated with changes, reflecting the customer's requirements. People across the globe work on the same piece of software at the same time hence, there is a need for techniques that allow a smooth evolution of database as the design develops. Such methods utilize automated refactoring and continuous integration so that it supports agile methodologies for software development. These development techniques are applied on systems that are in pre-production stage as well on systems that have already been released. These techniques not only cover relevant changes in the database schema according to customer's changing needs, but also migration of modified data into the database and also customizing the database access code accordingly without changing the data semantics.
Distributed agile software development is a research area that considers the effects of applying the principles of agile software development to a globally distributed development setting, with the goal of overcoming challenges in projects which are geographically distributed.
