Enterprise unified process

Last updated

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 and Michael Vizdos. [1] 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. [2] It deals with software development as seen from the customer's point of view.

Contents

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

To these EUP adds two additional phases

Disciplines

The rational unified process defines nine project disciplines

To these EUP adds one additional project discipline

and seven enterprise disciplines

Best practices of EUP

The EUP provides following best practices:-

  1. Develop iteratively
  2. Manage requirements
  3. Proven architecture
  4. Modeling
  5. Continuously verify quality.
  6. Manage change
  7. Collaborative development
  8. Look beyond development.
  9. Deliver working software on a regular basis
  10. Manage risk

The waterfall model is a breakdown of project activities into linear sequential phases, meaning they are passed down onto each other, where each phase depends on the deliverables of the previous one and corresponds to a specialization of tasks. The approach is typical for certain areas of engineering design. In software development, it tends to be among the less iterative and flexible approaches, as progress flows in largely one direction through the phases of conception, initiation, analysis, design, construction, testing, deployment and maintenance. The waterfall model is the earliest SDLC approach that was used in software development.

A software company is an organisation — owned either by the state or private — established for profit whose primary products are various forms of software, software technology, distribution, and software product development. They make up the software industry.

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.

In software development, 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), 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.

<span class="mw-page-title-main">Business process modeling</span> Activity of representing processes of an enterprise

Business process modeling (BPM) in business process management and systems engineering is the activity of representing processes of an enterprise, so that the current business processes may be analyzed, improved, and automated. BPM is typically performed by business analysts, who provide expertise in the modeling discipline; by subject matter experts, who have specialized knowledge of the processes being modeled; or more commonly by a team comprising both. Alternatively, the process model can be derived directly from events' logs using process mining tools.

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.

Model-driven engineering (MDE) is a software development methodology that focuses on creating and exploiting domain models, which are conceptual models of all the topics related to a specific problem. Hence, it highlights and aims at abstract representations of the knowledge and activities that govern a particular application domain, rather than the computing concepts.

The unified software development process or unified process is an iterative and incremental software development process framework. The best-known and extensively documented refinement of the unified process is the rational unified process (RUP). Other examples are OpenUP and agile unified process.

Software quality management (SQM) is a management process that aims to develop and manage the quality of software in such a way so as to best ensure that the product meets the quality standards expected by the customer while also meeting any necessary regulatory and developer requirements, if any. Software quality managers require software to be tested before it is released to the market, and they do this using a cyclical process-based quality assessment in order to reveal and fix bugs before release. Their job is not only to ensure their software is in good shape for the consumer but also to encourage a culture of quality throughout the enterprise.

Agile testing is a software testing practice that follows the principles of agile software development. Agile testing involves all members of a cross-functional agile team, with special expertise contributed by testers, to ensure delivering the business value desired by the customer at frequent intervals, working at a sustainable pace. Specification by example is used to capture examples of desired and undesired behavior and guide coding.

In software engineering, a software development process is a process of planning and managing software development. It typically involves dividing software development work into smaller, parallel, or sequential steps or sub-processes to improve design and/or product management. It is also known as a software development life cycle (SDLC). The methodology may include the pre-definition of specific deliverables and artifacts that are created and completed by a project team to develop or maintain an application.

Release management is the process of managing, planning, scheduling and controlling a software build through different stages and environments; it includes testing and deploying software releases.

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.

Agile usability engineering is a method created from a combination of agile software development and usability engineering practices. Agile usability engineering attempts to apply the principles of rapid and iterative development to the field of user interface design.

Agile architecture means how enterprise architects, system architects and software architects apply architectural practice in agile software development. A number of commentators have identified a tension between traditional software architecture and agile methods along the axis of adaptation versus anticipation.

The entity-control-boundary (ECB), or entity-boundary-control (EBC), or boundary-control-entity (BCE) is an architectural pattern used in use-case driven object-oriented programming that structures the classes composing high-level object-oriented source code according to their responsibilities in the use-case realization.
