Importance of Software development methodologies
The ultimate objective of software engineering is to produce good quality maintainable software within reasonable time frame and at an affordable cost. This is achievable only if we have matured processes to produce it. For a mature process, it should be possible to determine in advance how much time and effort would be required to produce the final product. Software development organizations follow some method when developing a software product. This methodology refers to the framework that is used to structure, plan, and control the process of developing an information system. A wide variety of such frameworks have evolved over the years, each with its own recognized strengths and weaknesses. Common methodologies include waterfall, prototyping, iterative and incremental development, spiral development, rapid application development, and extreme programming. Often, several models are combined into some sort of hybrid methodology. These methods generally promote a disciplined project management process that encourages frequent inspection and adaptation.
The software development method typically includes a requirements phase, design phase, implementation phase, test phase, operation and maintenance phase. One software development methodology is not necessarily suitable for use by all projects. Each of the available methodologies is best suited to specific kinds of projects, based on various technical, organizational, project and team considerations. The choice of software development method can significantly affect overall costs associated with a software product.

...ll-defined unambiguous and complete policies will lead to the benefits of correct requirements. These requirements then lead to the generation of the correct product which meets the customer's needs preciously. The product therefore will include necessary features that will reduce the post-development cost.
Conclusion
We can conclude that any software project needs to be executed with a formally defined process.
The increased complexities and huge size of the software development projects make them tough to control without formal practices. If the software development process is weak the end product will undoubtedly suffer. Therefore the selection of the right process model is essential in developing a successful product. Also these formally defined development processes are likely to reduce the post-development costs due to early recognition of errors.
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.
This model is most effective for developing business software systems because it is easier to change the process to reflect the updated customer requirements. The basic idea behind incremental method is to develop a system through repeated cycles (iterative) and in smaller portions at a time (incremental), thereby allowing software developers to take advantage of what was learned during development of earlier parts or versions of the system. Learning comes from both the development and use of the system, where possible key steps in the process start with a simple implementation of a subset of the software requirements and iteratively enhance the evolving versions until the full system is implemented. At each iteration, design modifications are made and new functional capabilities are
SDLC( Software Development Life Cycle) , is a process used by the software industry to design, develop and test high quality software .The SDLC aim to produce good quality software that meets or exceeds the user’s expectation and reaches completion within time and cost estimates.
A software development process, also known as a software development life cycle (SDLC) can be explained as a structure, imposed on the development of a software product. The software development life cycle (SDLC) is an umbrella term for the overall process of developing, implementing, and retiring information systems through a multiple step process from initiation, training, documentation , design, analysis, maintenance, and consulting.
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).
The waterfall methodology flows in a downward fashion, similar to the way water flows downwards, take developers from the high-level initial requirements gathering through the system testing and product shipment. The waterfall methodology create blueprints or plans for the optimal process for software developme...
A software development methodology is a standard proven process which helps programmers, architects, system analysts and others to make a well controlled and an efficient progress in the high quality software development.
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.

...methodologies are an important part of information technology. There are several software development methodologies, and agile development methodologies are one of them. Agile development methodologies are a good method for software development. It has ability to develop system with Unclear User Requirements and Short Time Schedule in excellent. However, no specific methodology stands out as the one dominant method. It also has weakness such as not suitable with Unfamiliar Technology and Complex system. To survive, and grow, a methodology must be able to learn from other methodologies and adapt to changing customer requirements. This report is an overview of agile development methodologies and some of the common methodologies in agile development methodologies. It also provides example successfully project and ongoing project base on agile development methodologies.
The software engineering provides techniques to facilitate the development of computer projects. It deals with systematic and disciplined approach to the work and use of appropriate tools and optimum solutions for the problems to be solved. Software engineering uses the design principles and best practices for building quality software In a nutshell, it is the use of technologies and practices from computer science, design management and overall project management.
Requirements engineering begins during the communication activity, continues into the modeling activity, and builds a bridge from the system requirements into software design and construction. Through requirements engineering, there is an examination of the context of software work performed. It is essential for the software engineering team to understand all requirements of a problem before the team tries to solve the problem. An identification of specific needs that the design and construction must address is also included. Further is a need for the identification of the priorities that guides the order for the completion of work. This i...

Introduction: At a technical level, software engineering fundamental activities are Software specification, software development, software validation, and software evolution.
Documentation is vital on the grounds that it furnishes data for the staff to take in the new framework. It guarantees progression of frameworks improvement after the framework is conveyed for utilization and the first programmers or designers proceed onward to different activities. Client documentation is required for one to decrease the amount o...
