Learning Systems Development And Software Construction And Modeling

Developing software is far from an exact science and without a structured system to guide the process a project is likely to fail. Defining and adhering to a Software Development Life Cycle (SDLC) early in the project will help to guide the development of a new information system. In addition to having the structure for the development team to work within a defined and agree upon SDLC will help to set the proper expectations for deliverables with the stakeholders and customer(s). Smith Consulting has been given the task of creating a Frequent Shopper program for Kudler Fine Foods. As a result Smith Consulting needs to decide on which SDLC will work best for this project. In addition to selecting a SDLC to use Smith Consulting will

Big Corporations and Health care organization are always looking to improve their information systems to save time, money, and people lives. One most used information system would be the System Development Lifecycle (SDLC). A system development can sometimes run over budget or the corporation and organizations will never receive full satisfaction if their goals are not accomplish.

Agile is an iterative and incremental (evolutionary) approach to software development which is performed in a highly collaborative manner by self-organizing teams within an effective governance framework, with "just enough" ceremony, that produces high quality solutions, in a cost effective and timely manner which meets the changing needs of its stakeholders [1].

SC will compare traditional and various iterative implementations of the SDLC. For example, Braude and Bernstein (2011) state that the popular and mature waterfall process model promotes simple comprehension, project management, and resource distribution of small project development lifecycles. The serial nature of the traditional SDLC leans toward the gathering of all requirements at the beginning of the project whereas the majority of testing occurs at the end of the lifecycle. The waterfall model’s linear design creates disastrous risks for large projects if the project team does not understand the core requirements during the initial phase of the project or the detection of major problems occurs toward the end of the project. On the other hand, a spiral model significantly reduces risks for large projects whereas complexity causes overkill for smaller projects. The project’s physical scope, timeline, budget, and resource determine which the most optimal process model for a project. Table 1.1 displays a comparison chart that SC uses to weigh advantages and disadvantages of traditional SDLC and Agile development methodologies. SC will utilize this chart to determine which development methodology is utilized based on the primary amount of questions answered positively weighed with the clients business case requirements. “Agile software development is a

The structure and order of activities exercised for the advance of systems, are known as the “System Development Life Cycle”. The activities and processes within this outline are typically executed according to a sound defined and complete sets of process known as methodologies. These methodologies comprise specific actions for the requirement analysis as well as the design of mutually the data and development sections of the arrangement.

When it comes to systems development today, the most important decision every development team faces is which approach to use. Given the fact that information technology is continually growing, it is extremely important to shorten the time spent on the development as much as possible. This, however, is sometimes easier said than done. Because there are situations where the complexity of the system requires a huge amount of time to develop, it is much wiser to slow down and do things the right way rather than hurry and be forced to repeat the process again. Therefore, it is vital to choose the best approach. Although there are several different methodologies that can be used when it comes to systems development,

SDLC evolved from the need of systems to do systems (Roebuck, 2012). This is mainly because systems development is a rigorous to undertake, and requires a definite scope and disciplined process. According to Massey and Satao, SDLC involves an intricate process that has eventually led an increase in its specialization (2012). For instance,

A prerequisite to this approval is a Project Charter to be completed and signed off by the Operating or Corporate Group Leader. The SDLC begins with a cross-functional kick off meeting where the scope of the project is defined, the majority of requirements are identified, and priorities are set regarding need and timing. The requirements are documented as user stories and may be optionally captured within the user story tracking software (JIRA). This tool can also be leveraged to collect any additional clarification of functional design requirements.

 I will follow the Iterative model for developing this Project and whole Project will be developed using the SDLC scenario.

Computer system plays an important role in solving human problem in their daily life. There are standard steps in order to develop information system called System Development Life Cycle (SDLC). SDLC is the framework available to build a complete system. There are five phases in SDLC which are planning, analysis, design, coding, testing and maintenance (refer to Figure 1 in Appendix 1).

This essay involves the comparison and contrast of the different methodologies used by programming teams. Among these methodologies are; System development life cycle (SDLC), Extreme programming and Agile methodology. Software development methodologies are the frameworks involved to structure, plan and control the processes used in developing an information system. The system development life cycle (SDLC) is a conceptual model which is involved in most project management and used for large scale projects with relatively large number of developers. A good example of SDCL methodologies includes; waterfall model. The SDCL takes a lot of time to produce complete products but of high quality. Agile methodology is a conceptual framework used also in project management and it is designed for small projects with few developers. Extreme programming on the other hand allow for communication with customers and by doing so it ensures interaction between developers and consumers in order to change as fast as the customers' needs and desires changes. Even though there different methodologies, agile methodologies seem to have a lot of advantages over the Extreme programming and system development life cycle. Since it combines a number of other methodologies to come up with a better way for developer to produce faster and change to as customers desires changes.

Conventional heavyweight, document-driven software development methods can be characterized as extensive planning, codified process, reuse, heavy documentation and big design up front. These are some reason that conventional methods have been replaced by lightweight agile software development methods mostly in small-scale and relatively simple projects. This phenomenon is mainly due to the conventional methods’ shortcomings, including a slow adaptation to rapidly changing business requirements, and a tendency to be over budget and behind schedule The conventional methods also have not able to provide dramatic improvements in productivity, reliability, and simplicity. Despite the existing shortcomings, the conventional methods are still widely used in industry, particularly, for large-scale projects. Conventional methods come with their straightforward, methodical, and structured nature, as well as their capability to provide predictability, stability, and high assurance. Agile software development methods focus on iterative and incremental development, customer collaboration, and frequent delivery through a light and fast development life cycle. There are many positive benefits of the agile approaches.

Though many people interchange system engineering models and software engineering life cycle models, they are defined as two different approaches to software development. System engineering is the technical and technical management process that results in delivered products and systems that exhibit the best balance of cost and performance. As the program progresses from one phase to the next one, so does the system engineering process. It deals with the overall management of engineering project during their life cycle. Its main focus is knowing what the clients and end users wants and needs are satisfied and developing just that all the way through the system’s entire life cycle. Whereas, on the other hand, software engineering focuses on the quality of the product or system, how cost effective it is, is it done within the time-constraints given, whether it is easy to maintain and enhance, and does it work as the requirements defined. Its main focus is on delivering a product that meets the requirement specifications. There are so many models to choose from, as it all depends on what the project needs and entails. Depending on the requirements, allows for the choice of what mode to use.

I have expertise integrating aspects of information technology, computer science; project management (client, shareholder and student interactions covering all SDLC phases), which converge in a comprehensive domain of disciplines. I present innovative, cross-disciplinary solutions to unknown problem areas.

As we saw throughout the last forty or so years is that computer systems frequently evolve and that developmental change is inevitable and software development is no stranger to this, which is where agile development or the term that some use agile software development comes into play. This is a concept that searches for alternatives to the traditional way of managing a project and based on the foundation that change is essential to software development. Throughout this paper, we will look at the reasons that brought about the change in thinking with regard to software development, discuss some of the key principles of agile development, methods under agile development and the benefits of the use of agile development. Let’s begin this document with a discussion into what brought about the change in thinking.
