Function (engineering)In engineering, a function is interpreted as a specific process, action or task that a system is able to perform. In engineering designIn the lifecycle of engineering projects, there are usually distinguished subsequently: Requirements and Functional specification documents. The Requirements usually specifies the most important attributes of the requested system.Product requirements documentA product requirements document (PRD) is a document containing all the requirements for a certain product. It is written to allow people to understand what a product should do. A PRD should, however, generally avoid anticipating or defining how the product will do it in order to later allow interface designers and engineers to use their expertise to provide the optimal solution to the requirements.
Requirements analysisEngineering process A systems engineering perspective on 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 stakeholders, analyzing, documenting, validating, and managing software or system requirements.
Software developmentSoftware development is the process of designing, creating, testing, and maintaining software applications to meet specific user needs or business objectives. The process is more encompassing than programming, writing code, because it includes conceiving the goal, evaluating feasibility, analyzing requirements, design, testing and release.Test case (software)In software engineering, a test case is a specification of the inputs, execution conditions, testing procedure, and expected results that define a single test to be executed to achieve a particular software testing objective, such as to exercise a particular program path or to verify compliance with a specific requirement. Test cases underlie testing that is methodical rather than haphazard.
Systems engineeringSystems engineering is an interdisciplinary field of engineering and engineering management that focuses on how to design, integrate, and manage complex systems over their life cycles. At its core, systems engineering utilizes systems thinking principles to organize the systems engineering body of knowledge.
DebuggingIn engineering, debugging is the process of finding the root cause, workarounds, and possible fixes for bugs. For software, debugging tactics can involve interactive debugging, control flow analysis, log file analysis, monitoring at the application or system level, memory dumps, and profiling. Many programming languages and software development tools also offer programs to aid in debugging, known as debuggers.
User (computing)A user is a person who uses a computer or networkservice. A user typically has a user account and is recognized by the system through a username. Some software products provide services to other systems and have no direct end users. End userEnd users are the ultimate human users (also referred to as operators) of a software product. The end user stands in contrast to users who support or maintain the product such as sysops, database administrators and computer technicians.
SoftwareSoftware (SW) consists of computer programs that instruct the execution of a computer. Software also includes design documents and specifications. The history of software is closely tied to the development of digital computers in the mid-20th century. Early programs were written in the machine language specific to the hardware.Stakeholder (corporate)In a corporation, a stakeholder is a member of "groups without whose support the organization would cease to exist", as defined in the first usage of the word in a 1963 internal memorandum at the Stanford Research Institute.
Source CodeSource Code is a 2011 science fictionaction thriller film directed by Duncan Jones and written by Ben Ripley. It stars Jake Gyllenhaal as a US Army officer who is sent into an eight-minute virtual re-creation of a real-life train explosion, and tasked with determining the identity of the terrorist who bombed it. Michelle Monaghan, Vera Farmiga, and Jeffrey Wright play supporting roles.
ProgrammerA programmer, computer programmer or coder is an author of computer source code, or someone with skill in computer programming. The professional titles software developer and software engineer may be used for jobs that require a programmer.*As an Amazon Associate I earn from qualifying purchases.
