Each model of change represents different ideas and theories of how successful change can occur. The main focus in this report is to explore three existing models used today, designed to effectively achieve change. Also, introduction of a model created specifically for this paper, inspired by the theories of each of the models discussed will be explored. The Transformational Change Model otherwise known as the R.I.S.E. Model, the Trans-Theoretical model and Bridges' Transition are the three existing

IT 460 Unit 1 Kaplan University Harold Boyd The first thing I am going to talk about is JAD (Joint Application Development). Joint Application Development (JAD) is a development technique used to help IT developers build systems. This technique was developed by IBM in the 1970's. In this technique, a team is formed of members of different backgrounds. These members are made up of end-users, management, and IT staff. This team meets and discusses the current project in a number of workshops/sessions

The consistency model provided by a given DSM implementation attempts to balance performance and ease of programming: while DSM provides the abstraction of shared memory, it is not true shared memory - both from the point of view of the semantics and the cost of shared memory access. The focus of this paper is to identify the issues involved in the design of DSM systems, briefly highlight the mechanisms in use by some current DSM implementations and propose some new DSM models for future distributed

development life cycle, and compare the SDLC waterfall model with the spiral model? “The Systems Development Life Cycle (SDLC) is a conceptual model used in project management that describes the stages involved in an information system development project from an initial feasibility study through maintenance of the completed application. Various SDLC methodologies have been developed to guide the processes involved including the waterfall model (the original SDLC method), rapid application development

The relational algebra is a theoretical language with operations that work on one or more relations to define another relation without changing the original relation. Thus, both the operands and the results are relations; hence the output from one operation can become the input to another operation. This allows expressions to be nested in the relational algebra. This property is called closure. Relational algebra is an abstract language, which means that the queries formulated in relational

structure of an information system. In this chapter, the theories used in the development of the proposed system will be discussed. In line with this is the database system, which uses a normalized database to encapsulate the constructs of a data model, to eliminate data redundancy, organized data effectively and to trim down irregularities during data operations. Another is the used of the Third-Generation Programming Language, also known as 3GL Computer Language like Visual Basic 6, a further
