Introduction
This paper has the intention to explain what Rational Unified Process (RUP) is like an IBM product and a CASE tool. After is explained what phases it has, what are the most common extensions thus what are its workflows more used. The Rational Unified Process (RUP) is a software design method created by the Rational Software Corporation and now is part of IBM developer software. This paper describes how to deploy software effectively. The Rational Unified Process (RUP) use commercially proven techniques, and is a heavy weight process, and hence particularly applicable to larger software development teams working on large projects.
Rational Unified Process (RUP)
Rational Unified Process (RUP) is an object-oriented and Web-enabled program development methodology. RUP would be taken like an online mentor that provides guidelines, templates, and examples for all aspects and stages of program development. RUP is a comprehensive software engineering tool that combine the procedural aspects of development (such as defined stages, techniques, and practices) with other components of development (such as documents, models, manuals, code, and so on) within a unifying framework.
The RUP defines the following guidelines and templates for team members to follow during a product’s lifecycle:
Develop Software Iteratively
Given the time, it takes to develop large sophisticated software systems it not possible to define the problem and build the solution in a single step. Requirements will often change throughout a projects development, due to architectural constraints, customer’s needs or a greater understanding of the original problem. Iteration allows greater understanding of a project through successive refinements and addresses a projects highest risk items at every stage of its lifecycle. Ideally each iteration ends up with an executable release – this helps reduce a projects risk profile, allows greater customer feedback and help developers stay focused.
Manage Requirements
A documentation framework is essential for any large project; hence, RUP describes how to document functionality, constraints, design decisions and business requirements. Use Cases and Scenarios, are examples of artifacts prescribed by the process and have been found to be very effective at both capturing functional requirements and providing coherent threads throughout the development and deployment of the system.
Use component based architecture
Component Based Architecture creates a system that is easily extensible, promotes software reuse and intuitively understandable. A component often relates to an object in Object Orientated Programming. The RUP provides a systematic way to build this kind of system, focusing on producing an early executable architecture before committing full resources on a project.
The Software Development Life Cycle is seldom used at my place of work. Unfortunately, recent developments in its use are deemed confidential. Due to this fact, this paper will examine in general terms one of the projects we are undertaking right now while at the same time attempting to maintain our confidentiality.
Another process activity useful for the prediction of changes is requirements-driven impact analysis or RIDA, for short. This analysis is used to pinpoint which software entities need to be altered in order to be able to implement a certain requirement (Lindvall, 1998). RIDA, which is conducted during the release planning phase, takes two variables into consideration. Firstly, there is the input, which refers to the existing complex system and the set of requirements. Secondly, there is the output, which represents the specific software entities that have to be changed to meet each requirement.
Controlled Requirement Expression (CORE) was developed for the British Aerospace programs while the UK Ministry of Defence was carrying out a requirement analysis (Hull et al., 2010). The fundamental component of the CORE methodology is viewpoints as different users see systems in different ways. There are many different stakeholders involved in a system; using CORE methodology involves finding all the different viewpoints of those stakeholders that have an interest in the system whether it’s a person, role or organisation ext.… (Sommerville and Sawyer, 2000). By organising viewpoints hierarchy it assists experts to read the scope and supports the analysis process. CORE Methodology is extensively used for real time system requirements specification.
This phase is the main focus of the project managers and stake holders. Meetings with managers, stake holders and users are held in order to determine the requirements like; Who is going to use the system? How will they use the system? What data should be input into the system? What data should be output by the system? These are general questions that get answered during a requirements gathering phase. After requirement gathering these requirements are analyzed for their validity and the possibility of incorporating the requirements in the system to be development is also studied.
A framework is a set of classes that supports reuse at larger granularity. It defines an object-oriented abstract design for a particular kind of application which enables not only source code reuse, but also design reuse [Johnson & Foote, 1988]. The framework abstract structure can be filled with classes from its own library or application-specific ones, providing flexibility for the developer to adapt its behavior to each application. Besides flexibility, a good framework also increases the team productivity and makes application maintenance easier [Fayad et al. 1999].
While developing a software many complex activities are required which in turn have dependencies along them. Large software projects require the involvement of programmers, documentation specialists, program managers, architects, database analysts, system analysts, , and trainers and last but not the least testers. Along with their independent responsibilities these persons are also responsible to maintain and keep a check on the software system quality as well.
Purpose - The purpose of this Risk Management Plan (RMP) is to describe the methodology that the PPW Company will use in identifying, tracking, mitigating, and ultimately reducing risks that we have identified in the Knowledge Management System. This document will define the risk management roles and responsibilities of the project team.
In today's world there is very unusual to have a program developed that will not have further development after release. The requirements of the time that we live are very dynamic and there is a need for constant adaptation. A basic requirement for any new software product is to be adaptable, easy to maintain and modify. Time factor and cost factor are ruling in the agitated competition and only those who are well organized and prepared are able to survive. The question for software maintenance and change control is taking key position in both perspectives: the perspective of the manufacturer of the software, and the perspective of the consumer. In the negotiation and management of these two major players is the complexity of the software maintenance and change control. In this paper we will focus on some important specifics of these processes.
The Systems Development Life Cycle (SDLC) consists of phases used in developing a piece of software. It is the plan of how to develop and maintain software, and when necessary, replace that software. In 2007 during my hospital’s transition to a new software system, I was fortunate enough to be included in the process. I did not get involved until the implementation phase, but from then on, until now, I remain very active in the process. I decided to highlight the Waterfall Model of SDLC. The Waterfall Model is a “sequential development process” with each phase continuing in a line (McGonigle and Mastrian, 2012, p. 205).
Encouraging software reuse improves the dependability of a product, as a reusable software unit is tried and tested. It reduces the risk of developing a large component from scratch, as it is easy to estimate the cost of using a large reusable software unit. Apart from ensuring quick product delivery, it enables the architects to reuse patterns and architectures suitable for particular situation, and the developers to use a set of program libraries, which eventually reduce the time for development.
The Unified Modeling Language is a standard language for specifying, visualizing, constructing, and documenting the artifacts of software systems, as well as for business modeling and other non-software systems. The key is to organize the design process in a way that clients, analysts, programmers and other involved in system development can understand and agree on. The UML provides the organization. The UML was released in 1997 as a method to diagram software design, by some of the best minds in object oriented analysis and design. It is by far the most exciting thin to happen to the software industry in recent years. Every other engineering discipline has a standard method of documentation. Electronic engineers have schematic diagrams; architects and mechanical engineers have blueprints and mechanical diagrams. The software industry now has UML.
Computer software is used by hundreds of millions of people daily. Software is all around us and can be found in our homes, businesses, schools and automobiles. Operating system software runs our desktops, laptops, and mobile devices such as iPhones and iPads. The development of these and other complex varieties of software often follow a software engineering process commonly referred to as a Systems Development Life Cycle (SDLC). Several methodologies describing the framework that encompasses the subsets of the tasks or activities that occur during this procedure exist, including
early 1990s saw the development of CORBA and Microsoft's COM, which was a natural extension of the ideas that had led to the original Windows API. This interface or component programming was a natural extension of encapsulation —a basic tenet of OOP, as we will see. All of these developments were aimed at further managing or reducing complexity. Since this was the original goal of OOP and these techniques are used in conjunction with classic OOP, we find it appropriate to consider them in a treatment on "OOP".
Most of the software development projects change just during the development is in process. This is the reason that agile methodology is best for these projects. There is a room for change in them. Software developers follow these methods and this is the reason that they have further modified these methods according to the different types of projects they confront in their development time.
The requirements phase gather the Information which assist in next phase of software engineering (software development). Requirement phase determines all the questions start from W such as after final development where the final product will be use, what type of users use it and what features or services it should provide. It is imperative to continue check and update the requirements up to when the appropriate requirements not finalize. Inadequate, incomplete or irrelative data or information of requirement may generates errors in next development phases of project. The main cause behind erroneous requirement definitions are distinct needs of several users groups and difference among their interest.
