Agile Unified Process
Agile Unified Process (AUP) is a simplified version of the Rational Unified Process (RUP) developed by Scott Ambler. It describes a simple, easy to understand approach to developing business application software using agile techniques and concepts yet still remaining true to the RUP. The AUP applies agile techniques including test-driven development (TDD), agile modeling (AM), agile change management, and database refactoring to improve productivity. In 2011 the AUP accounted for one percent of all the agile methodologies used. In 2012 the AUP was superseded by disciplined agile delivery (DAD). Since then work has ceased on evolving AUP. Discipline Unlike the RUP, the AUP has only seven disciplines : # Model. Understand the business of the organization, the problem domain being addressed by the project, and identify a viable solution to address the problem domain. # Implementation. Transform model(s) into executable code and perform a basic level of testing, in particular unit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rational Unified Process
The Rational Unified Process (RUP) is an iterative software development process framework created by the Rational Software Corporation, a division of IBM since 2003. RUP is not a single concrete prescriptive process, but rather an adaptable process framework, intended to be tailored by the development organizations and software project teams that will select the elements of the process that are appropriate for their needs. RUP is a specific implementation of the Unified Process. History Rational Software originally developed the rational unified process as a software process product. The product includes a hyperlinked knowledge-base with sample artifacts and detailed descriptions for many different types of activities. RUP is included in the IBM Rational Method Composer (RMC) product which allows customization of the process. Philippe Kruchten, an experienced Rational technical representative was tasked with heading up the original RUP team. These initial versions combined t ...

Test-driven Development
Test-driven development (TDD) is a software development process relying on software requirements being converted to test cases before software is fully developed, and tracking all software development by repeatedly testing the software against all test cases. This is as opposed to software being developed first and test cases created later. Software engineer Kent Beck, who is credited with having developed or "rediscovered" the technique, stated in 2003 that TDD encourages simple designs and inspires confidence. Test-driven development is related to the test-first programming concepts of extreme programming, begun in 1999, but more recently has created more general interest in its own right.Newkirk, JW and Vorontsov, AA. ''Test-Driven Development in Microsoft .NET'', Microsoft Press, 2004. Programmers also apply the concept to improving and debugging legacy code developed with older techniques.Feathers, M. Working Effectively with Legacy Code, Prentice Hall, 2004 Test-driven ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Agile Modeling
Agile modeling (AM) is a methodology for modeling and documenting software systems based on best practices. It is a collection of values and principles, that can be applied on an (agile) software development project. This methodology is more flexible than traditional modeling methods, making it a better fit in a fast changing environment. It is part of the agile software development tool kit. Agile modeling is a supplement to other agile development methodologies such as Scrum, extreme programming (XP), and Rational Unified Process (RUP). It is explicitly included as part of the disciplined agile delivery (DAD) framework. As per 2011 stats, agile modeling accounted for 1% of all agile software development. Agile modeling is one form of Agile model-driven engineering (Agile MDE), which has been adopted in several application areas such as web application development, finance, and automotive systems https://kclpure.kcl.ac.uk/portal/en/publications/the-integration-of-agile-develop ...

Database Refactoring
A database refactoring is a simple change to a database schema that improves its design while retaining both its behavioral and informational semantics. Database refactoring does not change the way data is interpreted or used and does not fix bugs or add new functionality. Every refactoring to a database leaves the system in a working state, thus not causing maintenance lags, provided the meaningful data exists in the production environment. A database refactoring is conceptually more difficult than a code refactoring; code refactorings only need to maintain behavioral semantics while database refactorings also must maintain informational semantics. A database schema is typically refactored for one of several reasons: # To develop the schema in an evolutionary manner in parallel with the evolutionary design of the rest of the system. # To fix design problems with an existing legacy database schema. Database refactorings are often motivated by the desire for database normaliza ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Disciplined Agile Delivery
Disciplined agile delivery (DAD) is the software development portion of the Disciplined Agile Toolkit. DAD enables teams to make simplified process decisions around incremental and iterative solution delivery. DAD builds on the many practices espoused by advocates of agile software development, including scrum, agile modeling, lean software development, and others. The primary reference for disciplined agile delivery is the book ''Choose Your WoW!'', written by Scott Ambler and Mark Lines. In particular, DAD has been identified as a means of moving beyond scrum. According to Cutter Senior Consultant Bhuvan Unhelkar, "DAD provides a carefully constructed mechanism that not only streamlines IT work, but more importantly, enables scaling." Paul Gorans and Philippe Kruchten call for more discipline in implementation of agile approaches and indicate that DAD, as an example framework, is "a hybrid agile approach to enterprise IT solution delivery that provides a solid foundation from ...

Unit Testing
In computer programming, unit testing is a software testing method by which individual units of source code—sets of one or more computer program modules together with associated control data, usage procedures, and operating procedures—are tested to determine whether they are fit for use. History Before unit testing, capture and replay testing tools were the norm. In 1997, Kent Beck and Erich Gamma developed and released JUnit, a unit test framework that became popular with Java developers. Google embraced automated testing around 2005–2006. Description Unit tests are typically automated tests written and run by software developers to ensure that a section of an application (known as the "unit") meets its design and behaves as intended. In procedural programming, a unit could be an entire module, but it is more commonly an individual function or procedure. In object-oriented programming, a unit is often an entire interface, such as a class, or an individual ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Configuration Management
Configuration management (CM) is a process for establishing and maintaining consistency of a product's performance, functional, and physical attributes with its requirements, design, and operational information throughout its life. The CM process is widely used by military engineering organizations to manage changes throughout the system lifecycle of complex systems, such as weapon systems, military vehicles, and information systems. Outside the military, the CM process is also used with IT service management as defined by ITIL, and with other domain models in the civil engineering and other industrial engineering segments such as roads, bridges, canals, dams, and buildings. Introduction CM applied over the life cycle of a system provides visibility and control of its performance, functional, and physical attributes. CM verifies that a system performs as intended, and is identified and documented in sufficient detail to support its projected life cycle. The CM process facilita ...

Project Management
Project management is the process of leading the work of a team to achieve all project goals within the given constraints. This information is usually described in project documentation, created at the beginning of the development process. The primary constraints are scope, time, and budget. The secondary challenge is to optimize the allocation of necessary inputs and apply them to meet pre-defined objectives. The objective of project management is to produce a complete project which complies with the client's objectives. In many cases, the objective of project management is also to shape or reform the client's brief to feasibly address the client's objectives. Once the client's objectives are clearly established, they should influence all decisions made by other people involved in the project – for example, project managers, designers, contractors, and subcontractors. Ill-defined or too tightly prescribed project management objectives are detrimental to decision-maki ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Agile Software Development
In software development, agile (sometimes written Agile) practices include requirements discovery and solutions improvement through the collaborative effort of self-organizing and cross-functional teams with their customer(s)/ end user(s), adaptive planning, evolutionary development, early delivery, continual improvement, and flexible responses to changes in requirements, capacity, and understanding of the problems to be solved. Popularized in the 2001 ''Manifesto for Agile Software Development'', these values and principles were derived from and underpin a broad range of software development frameworks, including Scrum and Kanban. While there is much anecdotal evidence that adopting agile practices and values improves the effectiveness of software professionals, teams and organizations, the empirical evidence is mixed and hard to find. History Iterative and incremental software development methods can be traced back as early as 1957, Gerald M. Weinberg, as quoted in " ...

Enterprise Unified Process
The Enterprise Unified Process (EUP) is an extended variant of the Unified Process and was developed by Scott W. Ambler and Larry Constantine in 2000, eventually reworked in 2005 by Ambler, John Nalbone anMichael Vizdos EUP was originally introduced to overcome some shortages of RUP, namely the lack of production and eventual retirement of a software system. So two phases and several new disciplines were added. EUP sees software development not as a standalone activity, but embedded in the lifecycle of the system (to be built or enhanced or replaced), the IT lifecycle of the enterprise and the organization/business lifecycle of the enterprise itself.Ambler et al (2005) p.7 It deals with software development as seen from the customer's point of view. In 2013 work began to evolve EUP to be based on Disciplined Agile Delivery instead of the Unified Process. Phases The Unified Process defines four project phases * Inception * Elaboration * Construction * Transition To these EUP add ...
