Change Control Board
In software development, projects and programs, a change control board (CCB) is a committee that consists of Subject Matter Experts (''SME'', e.g. software engineers, testing experts, etc.) and Managers (e.g. Quality Assurance managers), who decide whether to implement proposed changes to a project. The main objective of a CCB is to ensure the client accepts the project. Factors affecting a CCB's decision can include the project's phase of development, budget, schedule, and quality goals. Change control (see Scope management) is also part of Requirements engineering. CCBs are most associated with the waterfall method of software development, but can be seen as having analogues in some implementations of Agile software development. The Change Control Board will review any proposed changes from the original baseline requirements that were agreed upon with the client. If any change is agreed upon by the committee, the change is communicated to the project team and the client, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Software Development
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 involves writing and maintaining the source code, but in a broader sense, it includes all processes from the conception of the desired software through to the final manifestation of the software, typically in a planned and structured process. Software development also includes research, new development, prototyping, modification, reuse, re-engineering, maintenance, or any other activities that result in software products. Methodologies One system development methodology is not necessarily suitable for use by all projects. Each of the available methodologies are best suited to specific kinds of projects, based on various technical, organizational, project, and team considerations. Software development activities Identification of need The sou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scope (project Management)
In project management, scope is the defined features and functions of a product, or the scope of work needed to finish a project. Scope involves getting information required to start a project, including the features the product needs to meet its stakeholders' requirements. Project scope is oriented towards the work required and methods needed, while product scope is more oriented toward functional requirements. If requirements are not completely defined and described and if there is no effective change control in a project, scope or requirement creep may ensue. Scope management is listing the items to be produced or tasks to be done; their required quantity, quality, and variety; the time and resources available and agreed upon; and modifying the variable constraints by dynamic flexible juggling in the event of changed circumstances. See also *Cost overrun *Requirements management *Scope statement In project management, scope statements can take many forms depending on the t ...

Requirements Engineering
Requirements engineering (RE) is the process of defining, documenting, and maintaining requirements in the engineering design process. It is a common role in systems engineering and software engineering. The first use of the term ''requirements engineering'' was probably in 1964 in the conference paper "Maintenance, Maintainability, and System Requirements Engineering", but it did not come into general use until the late 1990s with the publication of an IEEE Computer Society tutorial in March 1997 and the establishment of a conference series on requirements engineering that has evolved into the International Requirements Engineering Conference. In the waterfall model, requirements engineering is presented as the first phase of the development process. Later development methods, including the Rational Unified Process (RUP) for software, assume that requirements engineering continues through a system's lifetime. Requirement management, which is a sub-function of Systems Enginee ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Waterfall Method
The waterfall model is a breakdown of project 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 ("downwards" like a waterfall) through the phases of conception, initiation, analysis, design, construction, testing, deployment and maintenance. The waterfall development model originated in the manufacturing and construction industries, where the highly structured physical environments meant that design changes became prohibitively expensive much sooner in the development process. When first adopted for software development, there were no recognised alternatives for knowledge-based creative work. History The first known presentation describ ...

Agile Software Development
In software development, agile (sometimes written 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), adaptive planning, evolutionary development, early delivery, continual improvement, and flexible responses to changes in requirements, capacity, and understanding of the problems to be solved. 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. While there is much anecdotal evidence that adopting agile practices and values improves the effectiveness of software professionals, teams and organizations, the empirical evidence is mixed and hard to find. History Iterative and incremental software development methods can be traced back as early as 1957, Gerald M. Weinberg, as quoted in " ...

Baseline (configuration Management)
In Configuration Management, a baseline is an agreed description of the attributes of a product, at a point in time, which serves as a basis for defining change. A change is a movement from this baseline state to a next state. The identification of significant changes from the baseline state is the central purpose of baseline identification.CMMI Product Team, "Chpt 7, Maturity Level 2: Managed, Configuration Management, SP 1.3," in ''Capability Maturity Model Integration, Version 1.1 (CMMI-SE/SW/IPPD/SS, V1.1): Staged Representation,'' Carnegie Mellon Software Engineering Institute. Typically, significant states are those that receive a formal approval status, either explicitly or implicitly. An approval status may be attributed to individual items, when a prior definition for that status has been established by project leaders, or signified by mere association to a particular established baseline. Nevertheless, this approval status is usually recognized publicly. A baseline ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Consensus-based Decision Making
Consensus decision-making or consensus process (often abbreviated to ''consensus'') are group decision-making processes in which participants develop and decide on proposals with the aim, or requirement, of acceptance by all. The focus on establishing agreement of at least the majority or the supermajority and avoiding unproductive opinion differentiates consensus from unanimity, which requires all participants to support a decision. Origin and meaning of terms The word ''consensus'' is Latin meaning "agreement, accord", derived from ''consentire'' meaning "feel together". Broadly, ''consensus'' relates to a generally accepted opinion, but in the context of this article refers to the process ''and'' the outcome of consensus decision-making (e.g. "to decide ''by'' consensus" and "''a'' consensus was reached"). History Consensus decision-making, as a self-described practice, originates from several nonviolent, direct action groups that were active in the Civil rights, Peace ...

Change-advisory Board
A change-advisory board (CAB) delivers support to a change-management team by advising on requested changes, assisting in the assessment and prioritization of changes. This body is generally made up of IT and Business representatives that include: a change manager, user managers and groups, product owners, technical experts, and possible third parties and customers (if required). Membership The CAB members should selectively be chosen to ensure that the requested changes are thoroughly checked and assessed from both a technical and business perspective. The considered change will dictate the required personnel to convene in a CAB meeting. These entities are not required to meet face-to-face on each requested change, but rather use electronic support and communication tools as a medium. It is however advised that a quarterly meeting is scheduled to review outstanding changes, sign off on approved changes and discuss any future major changes. A CAB offers multiple perspectives necess ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Project Management
Project management is the process of leading the work of a team to achieve all project goals within the given constraints. This information is usually described in project documentation, created at the beginning of the development process. The primary constraints are scope, time, and budget. The secondary challenge is to optimize the allocation of necessary inputs and apply them to meet pre-defined objectives. The objective of project management is to produce a complete project which complies with the client's objectives. In many cases, the objective of project management is also to shape or reform the client's brief to feasibly address the client's objectives. Once the client's objectives are clearly established, they should influence all decisions made by other people involved in the project – for example, project managers, designers, contractors, and subcontractors. Ill-defined or too tightly prescribed project management objectives are detrimental to decision-maki ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Configuration Management
Configuration management (CM) is a process for establishing and maintaining consistency of a product's performance, functional, and physical attributes with its requirements, design, and operational information throughout its life. The CM process is widely used by military engineering organizations to manage changes throughout the system lifecycle of complex systems, such as weapon systems, military vehicles, and information systems. Outside the military, the CM process is also used with IT service management as defined by ITIL, and with other domain models in the civil engineering and other industrial engineering segments such as roads, bridges, canals, dams, and buildings. Introduction CM applied over the life cycle of a system provides visibility and control of its performance, functional, and physical attributes. CM verifies that a system performs as intended, and is identified and documented in sufficient detail to support its projected life cycle. The CM process facilita ...
