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 may b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Configuration Management
Configuration management (CM) is a management 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 proces ...

State (computer Science)
In information technology and computer science, a system is described as stateful if it is designed to remember preceding events or user interactions; the remembered information is called the state of the system. The set of states a system can occupy is known as its state space. In a discrete system, the state space is countable and often finite. The system's internal behaviour or interaction with its environment consists of separately occurring individual actions or events, such as accepting input or producing output, that may or may not cause the system to change its state. Examples of such systems are digital logic circuits and components, automata and formal language, computer programs, and computers. The output of a digital circuit or deterministic computer program at any time is completely determined by its current inputs and its state. Digital logic circuit state Digital logic circuits can be divided into two types: combinational logic, whose output signals a ...

Project Plan
A project plan, is a series of structured tasks, objectives, and schedule to a complete a desired outcome, according to a project managers designs and purpose. According to the Project Management Body of Knowledge (PMBOK), is: "...a formal, approved document used to guide both ''project execution'' and ''project control''. The primary uses of the project plan are to document planning assumptions and decisions, facilitate communication among ''project stakeholders'', and document approved scope, cost, and schedule ''baselines''. A project plan may be sumarized or detailed." The latest edition of the PMBOK (v6) uses the term '' project charter'' to refer to the contract that the project sponsor and project manager use to agree on the initial vision of the project (scope, baseline, resources, objectives, etc.) at a high level. In the PMI methodology described in the PMBOK v5, the project charter and the project management plan are the two most important documents for describin ...

Milestone
A milestone is a numbered marker placed on a route such as a road, railway, railway line, canal or border, boundary. They can indicate the distance to towns, cities, and other places or landmarks like Mileage sign, mileage signs; or they can give their position on the route relative to some datum location. On roads they are typically located at the side or in a Central reservation, median or central reservation. They are alternatively known as mile markers (sometimes abbreviated MMs), mileposts or mile posts (sometimes abbreviated MPs). A "kilometric point" is a term used in Metrication, metricated areas, where distances are commonly measured in kilometres instead of miles. "Distance marker" is a generic unit-agnostic term. Milestones are installed to provide linear referencing points along the road. This can be used to reassure travellers that the proper path is being followed, and to indicate either distance travelled or the remaining distance to a destination. Such refer ...

Design Review (U
A design review is a milestone within a product development process whereby a design is evaluated against its requirements in order to verify the outcomes of previous activities and identify issues before committing to—and, if need be, to re-prioritise—further work. The ultimate design review, if successful, therefore triggers the product launch or product release. The conduct of design reviews is compulsory as part of design controls, when developing products in certain regulated contexts such as medical devices. By definition, a review must include persons who are external to the design team. Contents of a design review In order to evaluate a design against its requirements, a number of means may be considered, such as: *Physical tests. *Engineering simulations. *Examinations (Walk-through). Timing of design reviews Most formalised systems engineering processes recognise that the cost of correcting a fault increases as it progresses through the development process. Ad ...

Revision Control
Version control (also known as revision control, source control, and source code management) is the software engineering practice of controlling, organizing, and tracking different versions in history of computer files; primarily source code text files, but generally any type of file. Version control is a component of software configuration management. A ''version control system'' is a software tool that automates version control. Alternatively, version control is embedded as a feature of some systems such as word processors, spreadsheets, collaborative web docs, and content management systems, e.g., Wikipedia's page history. Version control includes viewing old versions and enables reverting a file to a previous version. Overview As teams develop software, it is common to deploy multiple versions of the same software, and for different developers to work on one or more different versions simultaneously. Bugs or features of the software are often only present in ce ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Unified Modeling Language
The Unified Modeling Language (UML) is a general-purpose visual modeling language that is intended to provide a standard way to visualize the design of a system. UML provides a standard notation for many types of diagrams which can be roughly divided into three main groups: behavior diagrams, interaction diagrams, and structure diagrams. The creation of UML was originally motivated by the desire to standardize the disparate notational systems and approaches to software design. It was developed at Rational Software in 1994–1995, with further development led by them through 1996. In 1997, UML was adopted as a standard by the Object Management Group (OMG) and has been managed by this organization ever since. In 2005, UML was also published by the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC) as the ISO/IEC 19501 standard. Since then the standard has been periodically revised to cover the latest revision of UML. In ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Baseline (budgeting)
Baseline budgeting is an accounting method the United States Federal Government uses to develop a budget for future years. Baseline budgeting uses current spending levels as the "baseline" for establishing future funding requirements and assumes future budgets will equal the current budget times the inflation rate times the population growth rate. Twice a year—generally in January and August—CBO prepares baseline projections of federal revenues, outlays, and the surplus or deficit. Those projections are designed to show what would happen if current budgetary policies were continued as is—that is, they serve as a benchmark for assessing possible changes in policy. They are not forecasts of actual budget outcomes, since the Congress will undoubtedly enact legislation that will change revenues and outlays. Similarly, they are not intended to represent the appropriate or desirable levels of federal taxes and spending.See Statement of Paul N. Van de Water cited above Baseline Acc ...

Audits
An audit is an "independent examination of financial information of any entity, whether profit oriented or not, irrespective of its size or legal form when such an examination is conducted with a view to express an opinion thereon." Auditing also attempts to ensure that the books of accounts are properly maintained by the concern as required by law. Auditors consider the propositions before them, obtain evidence, roll forward prior year working papers, and evaluate the propositions in their auditing report. Audits provide third-party assurance to various stakeholders that the subject matter is free from material misstatement. The term is most frequently applied to audits of the financial information relating to a legal person. Other commonly audited areas include: secretarial and compliance, internal controls, quality management, project management, water management, and energy conservation. As a result of an audit, stakeholders may evaluate and improve the effectiveness of ris ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Software Configuration Management
Software configuration management (SCM), a.k.a. software change and configuration management (SCCM), is the software engineering practice of tracking and controlling changes to a software system; part of the larger cross-disciplinary field of configuration management (CM). SCM includes version control and the establishment of baselines. Goals The goals of SCM include: * Configuration identification - Identifying configurations, configuration items and baselines. * Configuration control - Implementing a controlled change process. This is usually achieved by setting up a change control board whose primary function is to approve or reject all change requests that are sent against any baseline. * Configuration status accounting - Recording and reporting all the necessary information on the status of the development process. * Configuration auditing - Ensuring that configurations contain all their intended parts and are sound with respect to their specifying documents, inclu ...

Systems Development Life Cycle
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. Overview A systems development life cycle is composed of distinct work phases that are used by systems engineers and systems developers to deliver information systems. Like anything that is manufactured on an assembly line, an SDLC aims to produce high-quality systems that meet or exceed expectations, based on requirements, by delivering systems within scheduled time frames and cost estimates. Computer systems are complex ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
