IS development processes are the number of keys that involving in the development processes and referrers as the phrases of the systems development life-cycles, which is a traditional processes used to develop information systems. Some researchers has described that the basic task is playing a crucial role on the performance of successful build and maintain information systems. In fact, there are several projects that have been failure or success at the early phrases because of the disaster of making determination. For instance, the key stakeholder factor will have different responsibilities and engage in the successes or failure of the project. This relates to the efficiency communication processes such as consistent, accurate and timely

The concept development phase begins the life cycle when a need is identified and requires developing a system or change a legacy system identified. During this phase, the need is identified it is documented then a feasibility study is conducted. The approach selected should be approved and also funds to be used in the planning phase.  The EA enhances and allows the concept development phase.  It has an adaptable documentation option that can be used to document the discover needs. The planning phase starts after identifying the project and allocating resources to the project, and then a project plan is created. The plan records the process that will be used to solve the problem. The plan states the process and resources to be used in the project.   The requirement definition phase permits organizations to set and define the functional user requirements for a project. The functional user requirements are stated in the functional requirements document.  The requirements are grouped in categories such as data, system performance and security. The requirements are also assemble in terms of maintainability and support.  The managers determine whether the requirements offer the right basis to design the system. In this phase managers also

There are specific methodologies that organizations follow to develop and maintain their information systems. Systems Development Life Cycle (SDLC) is a conventional methodology that organizations adopt for system analysis and design. This life cycle contains five phases such as planning, analysis, design, implementation and maintenance (Hoffer, George & Valacich, 2008). At every stage of the SDLC, system analysts cooperate with other business professionals, programmers, professionals and testers to determine the progress of the system analysis and design.

There are many ways to develop an Information system, which is very complex. The systems development life cycle (SDLC) provides an overall efficient framework for managing the process of system development. Various organizations use information systems to support all kind of processes that a business needs to carry out its functions. There are different kind of information system and each has its own life, and system developer describe this idea as life cycle of system. During the life of an information system, it is first conceived as an idea; then it is designed, built, and deployed during a development project; and finally it is put into production and used to support the business. Projects during

System analysis and design is the scientific method of breaking down a system into its component pieces and studying how well those component parts work and interact to accomplish their main purpose. In essence, this course introduced me to the art of solving problems with the aim of making a person or an organization’s work easier and more efficient. In the course of learning, I learnt how system analysis and design employs a four pronged approach to solving these problems; planning, analysis, design and implementation. Mainly the system development life cycle (SDLC) is the process of understanding how information system can support business needs, designing the system, building it, and delivering it to users.

The Systems Development Life Cycle, in its variation shapes, stays one of the most established yet still broadly utilized strategies for programming improvement and obtaining techniques in the data innovation (IT) field. While it has advanced throughout the years because of regularly changing situations and outlook changes relating to the building or securing of programming, its focal inhabitants are as pertinent today as they ever were. Life-spin stages have experienced emphases of various names and number of steps, yet at the center the SDLC is flexible in its time tested sending in business, industry, and government. The SDLC Life Cycle has several different phases and every framework is not the same as the other as far as multifaceted

An Information System (IS) is commonly known as a system composed of people and computers whose main purpose is to processes or interprets information. In this context, information system development methodologies (ISDMs) are used to organize the IS development process (Zaied et al.2003). In the last decades, various well-known ISDMs have been established in literatures. For instance, Agile Methodology, Structured Systems Analysis and Design Methodology(SSADM), Soft Systems Methodology(SSM), User-centered Development Methodology, ETHICS Methodology, Jackson Systems Development(JSD) and etc. With these high level concepts of methodology for information system in mind, the rest of this research is focused on selecting a suitable development approach for the project, and identify the features and current thinking on the selected methodology.

A system development methodology refers to the framework that is used to structure, plan, and control the process of developing an information system. For a software company developing commercial software, and IT organization delivering business applications to users or Systems Integrators delivering solutions to the customers improving overall development lifecycles will yield benefits to both the company and their respective customers. A wide variety of such frameworks have evolved over the years, each with its own recognized strengths and weaknesses. Most important of them are

The system development life cycle framework provides a sequence of activities for system designers and developers to follow. It consists of a set of steps or phases in which each phase of the SDLC uses the results of the previous one.

A system development methodology refers to the framework that is used to structure, plan, and ascendency the process of developing an information system of an organisation. A wide variety of shows of such frameworks have evolved over the years, each with its own recognized enduringness and weaknesses. One system development methodology is not necessarily suitable for use by all projects. Each of the available methodologies is best suited to particular variety of projects, based on various technical foul requirements.

Information Technology (IT) is a critical and, oftentimes, complex component of an organization’s structure. Despite its importance, IT is often viewed as a ‘black hole’ by senior management of organizations- consuming valuable resources and assets. Unfortunately, this mentality can greatly hinder the economic advancement capabilities and capacities of an organization. As previously indicated, IT is a critical component to both the daily and future business needs of an organization. Senior managers of organizations must view IT as an essential piece of their company’s portfolio that can greatly increase the organization’s efficiency, earning potential and innovation.

SDLC life cycle defines a methodology to improve the quality of software and complete development process.

Businesses rely heavily on their information systems for decision making, an essential component of organization management. Information systems serves several purposes in a business, ranging from transactions and assisting leadership with difficult strategy formulation. Advances in computer-based information technology in recent years have led to a widely variety of systems that managers are now using to make and implement decisions (Alter, 1976). In today’s businesses, systems development is a process of examining a business situation to analyze better procedures and methods to stay competitive. System development life cycle (SDLC) methodologies are promoted as means of improving the management and control of the software development process, structuring and simplifying the process by specifying activities to be done and techniques to be used (Russo, 1995). Every businesses have different types of projects that have different requirements. Therefore, businesses must choose the SDLC phases according to the specific needs of the project. There are different types of SDLC. These are Waterfall Model, V-Shaped Model, Prototyping Model, Spiral Model, Iterative Incremental Model, and Extreme programming (Agile development) (Sami, 2012). Each of the models has different level of risks and benefits to cope with the project requirements. This paper will discuss the processes of System Development Life Cycle methodologies that makes it excessively formal and rigid and
