Software systems development is‚ from a historical perspective‚ a very young profession. The first official programmer is probably Grace Hopper‚ working for the Navy in the mid-1940s. More realistically‚ commercial applications development did not really take off until the early 1960s. These initial efforts are marked by a craftsman-like approach based on what intuitively felt right. Unfortunately‚ too many programmers had poor intuition. By the late 1960s it had become apparent that a more disciplined

The systems development life cycle (SDLC) is also known as the waterfall model. The systems development life cycle is a SDM (systems development methodology) that consists of seven phases. The seven phases are in a specific order that is completed phase by phase. The first phase is planning. The planning stage is where an outline is drawn up for preparations. During this phase a systems analyst‚ who may work for the company or be an outside consultant‚ will outline a proposed system‚ develop a budget

Overview Richard L. Nolan developed the theoretical Stages of growth model (SGM) during the 1970s. This is a general model‚ which describes the role of information technology (IT)‚ and how it grows within an organisation. A first draft of the model was made in 1973‚ consisting

Why are some pressure groups more successful than others? A pressure group is a group of people with specific aims and interests. Also known as interest groups‚ lobby groups or protest groups‚ they try to influence political decision makers such as MPs and councillors to influence local or national policy and/or legislation. They seek to do so‚ either to protect interests of members (e.g. Trade Unions‚ NUT) or promote a cause (e.g. Greenpeace or RSPCA). Not all pressure groups are as successful

Child Developmental Stages Child development comes in stages‚ and although not all children develop at the same rate‚ this timeline describes what typically occurs from the pre-natal stage through infancy and up to two years old. Pre-natal development is the most significant segment of human development. 15 days after conception the embryonic stage begins and continues until about the 8th week‚ or until the embryo is around an inch in length. The cells of the embryo are multiplying and taking

Introduction System development methodologies are promoted as a means of improving the management and control of the software development process‚ structuring and simplifying the process‚ and standardizing the development process and product by specifying activities to be done and techniques to be used. It is often tacitly assumed that the use of a system development methodology will improve system development productivity and quality. However‚ there is little empirical evidence to support this assumption
