...Software Develpoment Models Elizabeth Hicks Strayer University IT 106 Dr. Hines June 3, 2013 Software Development Models A software lifecycle model is a standardized format for planning, organizing, and running a new development project. Hundreds of different kinds of models are known and used. Some of these include waterfall, code and fix, spiral, rapid prototyping, unified process, agile methods extreme programming, and COTS. Many are minor variations on just a small number of basic models. It is important to survey the main types of model and to consider how to choose between them. A lifecycle model is a description of the sequence of activities carried out in an SE project, and the relative order of these activities. . By changing the lifecycle model we can improve and/or trade off development speed, product quality, project visibility, administrative overhead, risk exposure, and customer relations. Here is a quick overview along with some advantages and disadvantages of five different lifecycles. The waterfall model is the classic life cycle model. It is widely known, understood, and used. In some respect the waterfall is the “common sense” approach. It was introduced by Royce in 1970. Advantages include that they are easy to understand and implement, that they are widely used and known, and that it reinforces good habits: define-before-design, and design-before-code. It identifies deliverables and milestones, its document driven, and works well on mature products...

...The General Model-Software life cycle models describe phases of the software cycle and the order in which those phases are executed. There are tons of models, and many companies adopt their own, but all have very similar patterns. Each phase produces deliverables required by the next phase in the life cycle. Requirements- This phase is the main focus of the project managers and stake holders. Design-The software system design is produced from the results of the requirements phase. Implementation-Code is produced from the deliverables of the design phase during implementation, and this is the longest phase of the software development life cycle. Testing-During testing, the implementation is tested against the requirements to make sure that the product is actually solving the needs addressed and gathered during the requirements phase. (CIO.2002). Waterfall Model-This is the most common and classic of life cycle models, also referred to as a linear-sequential life cycle model. It is very simple to understand and use. In a waterfall model, each phase must be completed in its entirety before the next phase can begin. At the end of each phase, a review takes place to determine if the project is on the right path and whether or not to continue or discard the project. Unlike what I mentioned in the general model, phases do not overlap in a waterfall model. (DOJ,2003). Advantages- Simple and easy to use. Easy to manage due to the rigidity of the model – each phase has specific...

...to distinguish the advantages and disadvantages for different application methodologies. Since the company does not want to remain with SDLC, I am required to recommend either Joint Application Development (JAD) or Rapid Application Development (RAD). Therefore, I will provide information and allow the company president to make a decision based upon my research. JAD is a methodology that uses the design and development processes of an application. It is an information gathering technique used to design and develop computer-based systems. RAD is a shorter version of JAD; it reduces the time taken to develop an application (UMSL, 2014). The disadvantages of JAD are actually strengthening to a project; they just require a lot of accuracy. JAD require significant planning and scheduling to ensure the project is on task in correlation to the project plan. Furthermore, it involves much time and effort of stakeholders. For a successful project, JAD demands experienced and trained personnel (Directutor, 2010). On the contrary, the advantages of JAD are very relaxed and unrushed. It allows time for the gathering and reviewing large amounts of information. In result, high quality work may be produced. Discrepancies can be properly handled. Finally, team communication is increased. Overall, time is the number one advantage associated with JAD (Directutor, 2010). The disadvantages of RAD software development are that it should not be used for complex projects. Since it is a rapid...

...IT Management Ashley M. Evans MSI-501 06/04/2016 Ralph Reilly IT Management Information systems is a vital part of what organizations can do with their technology. The system development life cycle is a powerful mechanism for evaluating an organization's current and future SDLC needs (Norton, 2012). IT methodologies lay the blue print for being able to manage and accomplish projects when developing an organization’s needs. Traditional methodology and agile methodology are methodologies used. Traditional Methodology One example of traditional methodology is the waterfall approach. The waterfall follows the belief that all user requirements needed for the design can be collected upfront. This is referred to method makes the assumption that all requirements can be gathered up front during the requirements phase (Hughey, 2009). During this approach, the project manager tries their best to establish the user requirements. Once the user requirements are obtained the process starts. This process is known as downhill. The process goes through four phases. They are design, implementation, verification, and maintenance. To starts the design phase, an analysis is done to break the design in sub-phases logical design and physical design. During the Logical Design phase, the system's analysts makes use of the information collected in the Requirements phase to design the system independently of any hardware or software system (Hughey, 2009). Once the logical design has been...

Organizations use a standard set of steps, called system development methodology to develop and support their information systems. Like many processes, the development of information systems often follows a life cycle. For example, a commercial product such as a Nike sneaker or a Honda car follows a life cycle; it is created, tested and introduced to the market. Its sales increase, peak and decline. Finally, the product is removed from the market and is replaced with something else. Many options exist for developing information systems, but the most common methodology for system development in many organizations is system development life cycle. However, it is important to know other alternative development methodology available in order to...

...allows a business to assimilate all the primary business process in order to develop efficiency and retain a competitive position. However, improper implementation of the system might alter competitive advantage and improved productivity from surfacing. In its basic definition, ERP is an enterprise-wide information system that integrates and controls all the business processes in the entire organization. According to Nah and Lau (2001) ERP is "a packaged business software system that enables a company to manage the efficient and effective use of resources (materials, human resources, finance, etc.) by providing a total, integrated solution for the organization's information-processing needs". This software facilitates, if well-implemented, the integration of all the functional information flows across the organization into a single package with a common database. Therefore, it allows easy and immediate access to information regarding inventory, product or customer data, and prior history information (Shehab et al., 2004). As a project manager of a company, it is very important to obtain proper fundamental input about the company's compatibility with EPR, the market, and the information technology status, before taking the decision of adopting an ERP system. What most project managers fall into while making such a big decision is focusing on the system itself rather than crafting the suitable procedure to implementing and utilizing the new system. The aim of this research is...

...The V Model The V-Model has proven very popular over recent years and has probably replaced the Waterfall Model as the established model of software development. It is interesting to consider that the V-Model could not have existed without the prior experiences gained from usage of the Waterfall Model. If the Waterfall Model is the stern father then the V-Model is the popular son. Delve deeper into its usage and application, however, and one sees that it is not a panacea for all software development ills. Consider the representation of the V-Model below: The V-Model You can take the V-Model as a Waterfall Model snapped in the middle and bent upwards. You then have two 'stalks'; in broad terms, the left stalk represents design activities and the right stalk represents test activities. The flow is from the top left point of the 'vee' where the Statement Of the User Propblem (SOUP) is defined, down to the vertex where code is created and unit tested, up to the top right point of the 'vee' where the end-user validates the software against the original needs as defined by the SOUP. Whereas the Waterfall Model represents a series of sequential steps, the V-Model recognises the increasing importance of testing in the lifecycle. Testing, in the form of planning and review of requirement specifications and design specifications, starts right at the beginning of the lifecycle, unlike the older model where test activities are started further down the line . SOUP & User Acceptance...
