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.

Object-oriented analysis and design (OOAD) is a technical approach for analyzing and designing an application, system, or business by applying object-oriented programming, as well as using visual modeling throughout the software development process to guide stakeholder communication and product quality.
Systems analysis and design, an interdisciplinary part of science, may refer to: Systems analysis , a method of studying a system by examining its component parts and their interactions Structured data analysis (systems analysis) , analysing the flow of information within an organization with data-flow diagrams
The main target of this methodology framework in the 1960s was "to develop large scale functional business systems in an age of large scale business conglomerates. Information systems activities revolved around heavy data processing and number crunching routines." [2] Requirements gathering and analysis: The first phase of the custom software ...
Systems analysis is "the process of studying a procedure or business to identify its goal and purposes and create systems and procedures that will efficiently achieve them". Another view sees systems analysis as a problem-solving technique that breaks a system down into its component pieces and analyses how well those parts work and interact to ...
Business needs analysis. Adequate IT infrastructure. Effective change management. Ongoing continuous improvement. The aspects of a BPM effort that are modified include organizational structures, management systems, employee responsibilities, and performance measurements, incentive systems, skills development, and the use of IT.
The waterfall model is a breakdown of developmental activities into linear sequential phases, meaning that each phase is passed down onto each other, where each phase depends on the deliverables of the previous one and corresponds to a specialization of tasks. [1] This approach is typical for certain areas of engineering design.
Business systems planning (BSP) is a method of analyzing, defining and designing the information architecture of organizations. It was introduced by IBM for internal use only in 1981, [1] although initial work on BSP began during the early 1970s. BSP was later sold to organizations. [2]
