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. Requirements management, which is a sub-function of Systems En ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Requirements Analysis
In systems engineering and software engineering, requirements analysis focuses on the tasks that determine the needs or conditions to meet the new or altered product or project, taking account of the possibly conflicting requirements of the various Stakeholder (corporate), stakeholders, ''analyzing'', ''documenting'', ''validating'', and ''managing'' software or system requirements. Requirements analysis is critical to the success or failure of systems or Software project management, software projects. The requirements should be documented, actionable, measurable, testable, traceable, related to identified business needs or opportunities, and defined to a level of detail sufficient for Systems design, system design. Overview Conceptually, requirements analysis includes three types of activities: *Requirements elicitation, Eliciting requirements: (e.g. the project charter or definition), business process documentation, and stakeholder interviews. This is sometimes also calle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

List Of Requirements Engineering Tools
Requirements engineering tools are usually software products to ease the requirements engineering (RE) processes and allow for more systematic and formalized handling of requirements, change management and traceability. The PMI guide ''Requirements Management: A Practical Guide'' recommends that a requirements tool should be identified at the beginning of the project, as equirementstraceability can get complex and that switching tool mid-term could present a challenge. According to ISO/IEC TR 24766:2009, six major tool capabilities exist: # Requirements elicitation # Requirements analysis # Requirements specification # Requirements verification and validation # Requirements management # Other capabilities Note that INCOSE and Project Performance International (PPI) maintain an official database of tools, the Systems Engineering Tools Database (SETDB). RE tool list As with most software, the vendor/owner, tool name or scope change over time.(https://www.Reqops.com) Note th ...

Illusion
An illusion is a distortion of the senses, which can reveal how the mind normally organizes and interprets sensory stimulation. Although illusions distort the human perception of reality, they are generally shared by most people. Illusions may occur with any of the human senses, but visual illusions ( optical illusions) are the best-known and understood. The emphasis on visual illusions occurs because vision often dominates the other senses. For example, individuals watching a ventriloquist will perceive the voice as coming from the dummy since they are able to see the dummy mouth the words. Some illusions are based on general assumptions the brain makes during perception. These assumptions are made using organizational principles (e.g., Gestalt theory), an individual's capacity for depth perception and motion perception, and perceptual constancy. Other illusions occur due to biological sensory structures within the human body or conditions outside the body within one's phys ...

Requirements Validation
In engineering, a requirement is a condition that must be satisfied for the output of a work effort to be acceptable. It is an explicit, objective, clear and often quantitative description of a condition to be satisfied by a material, design, product, or service. A specification or spec is a set of requirements that is typically used by developers in the design stage of product development and by testers in their verification process. With iterative and incremental development such as agile software development, requirements are developed in parallel with design and implementation. With the waterfall model, requirements are completed before design or implementation start. Requirements are used in many engineering fields including engineering design, system engineering, software engineering, enterprise engineering, product development, and process optimization. Requirement is a relatively broad concept that can describe any necessary or desired function, attribute, capability ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Software Requirements Specification
A software requirements specification (SRS) is a description of a software system to be developed. It is modeled after the business requirements specification (CONOPS). The software requirements specification lays out functional and non-functional requirements, and it may include a set of use cases that describe user interactions that the software must provide to the user for perfect interaction. Software requirements specifications establish the basis for an agreement between customers and contractors or suppliers on how the software product should function (in a market-driven project, these roles may be played by the marketing and development divisions). Software requirements specification is a rigorous assessment of requirements before the more specific system design stages, and its goal is to reduce later redesign. It should also provide a realistic basis for estimating product costs, risks, and schedules. Used appropriately, software requirements specifications can he ...

System Modeling
A system is a group of interacting or interrelated elements that act according to a set of rules to form a unified whole. A system, surrounded and influenced by its environment, is described by its boundaries, structure and purpose and is expressed in its functioning. Systems are the subjects of study of systems theory and other systems sciences. Systems have several common properties and characteristics, including structure, function(s), behavior and interconnectivity. Etymology The term ''system'' comes from the Latin word ''systēma'', in turn from Greek ''systēma'': "whole concept made of several parts or members, system", literary "composition"."σύστημα" , Henry George Liddell, Robert Scott, '' |
Lifecycle Modeling Language
The Lifecycle Modeling Language (LML) is an open-standard modeling language designed for systems engineering. It supports the full lifecycle: conceptual, utilization, support and retirement stages. Along with the integration of all lifecycle disciplines including, program management, systems and design engineering, verification and validation, deployment and maintenance into one framework. LML was originally designed by the LML steering committee. The specification was published October 17, 2013. This is a modeling language like UML and SysML that supports additional project management uses such as risk analysis and scheduling. LML uses common language to define its modeling elements such as entity, attribute, schedule, cost, and relationship. Overview LML communicates cost, schedule and performance to all stakeholders in the system lifecycle. LML combines the logical constructs with an ontology to capture information. SysML is mainly constructs and has a limited ontology, whi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
