Application Of A Software Development Model

This research paper will be focus on different software modeling techniques. Software modeling is concerned with development process of software. Software modeling is central part of almost all activities that took place in software development. These models help us to envision a system according to our requirement by describing the structure and behavior of the system. There are three basic techniques of software modeling; object oriented modeling, dynamic modeling and functional modeling. Object oriented modeling concept start in 1990s, its basic building block is object that is the instant of any class, and here class is a template containing attributes and methods of objects. Classes and their relationships are present in class diagram. As a class have many type of relations with other class within a class diagram. These relationships are about inheritance and some are about

As the world became more and more dependent on technology with each passing day, software automatically became an important organ for development. Since software is needed almost everywhere today, its development is a highly intelligent and precise process, involving various steps. Known as software development life cycle, these steps include planning, analysis, design, development & implementation, testing and maintenance. These steps go on to create the perfect software for clients. ”

In Early 2000s, various software systems development methodologies were introduced and were started getting popular. One of them was agile method. Agile is a group of the latest and popular software systems development life cycle methodologies work in iterative way. All the requirements/needs and solutions are solved through collaboration between a development team and a business stakeholder. Agile method usually enhances an organized project management method which promotes regular assessment and revision. And the scrum is a sub group of agile. It is an iterative and incremental agile software development methodology for managing complex software and product development (“The Scrum Guide”).

Base on the analysis the reference, the general consensus in the research is that this enterprise project fell into the most basic traps of software development, from poor planning to bad communications throughout the lifecycle of the project. Our team will focus on the following aspects including scope, human resource, procurement, unrealistic scheduling, contracting and contract management, program management and enterprise architecture, the report will analyze each topic and make corresponding recommendation to improve the practice.

As has been observed in Part A, the software team are limited by their lack in numbers and hence are not able to fill each of Barry’s four key roles that are required for a self-managed team succeed. Furthermore, as noted in Part A, the software team experiences a lot of conflict.

The way that software is developed has been rapidly evolving over time, going through many iterations, one genre of which is Agile software development. The Agile Manifesto1 was published in 2001, however the ideas behind it have existed and used since the early 1970’s when E. A. Edmonds published a paper that introduced the idea of an adaptive software development process2. Then in the 1990’s there was a rapid evolution of software development processes. This lead to the creation of scrum in 1995, extreme programming in 1996 and feature-driven development in 1997. Though they were devised before the Agile Manifesto was created, they now all fall under Agile software development. Agile software development methods are generally considered much better than previous methods, such as the Waterfall method, though it is still considered to be in its early stages with many issues3.

Software development is a complex process where focus is on fast delivery of software products in cost effective manner (Mohammad, Alwada’n, & Ababneh, 2013).

Software development is no easy task. There are many ways to plan and execute the development of a software application. The biggest problem facing developers is to figure out which processes will work best for them. There are many things a developer needs ask themselves when planning a product. Requirements gathering has many ways to be accomplished, but which is the best? Should a waterfall style of development be used, or does agile offer more important features? Would it save time to develop in a test-driven environment? What is the most accurate way to estimate the time needed to complete the project? Is there an architecture that would be more efficient for this product? How can the documentation be kept up to pace with the code?

A software development methodology is a structure imposed on the development of a software product. It is used to structure, plan and control the process of developing an information system including procedures, techniques, tools and documentation aids. A wide variety of methodologies have evolved over the years, majority aggress that all these methodologies are distinguished into two categories – Heavyweight or Lightweight. Heavyweight methodologies are also known as traditional methodologies which approach system development with standard, well-defined processes such as Waterfall, Spiral and Unified Process. Lightweight methodologies

John W. Brackett states that “The subject of software requirements is often given far less attention in software engineering education Because of the dependence of this module on than software design, even though its importance is Software Specification: The hardest single part of building a software system is deciding precisely what to build. No other part of the conceptual work is as difficult as establishing the detailed technical requirements, including all the inter-faces to people, to machines and to other software systems. No part of the work so cripples the resulting system if done wrong. No other part is more difficult to rectify later” (Brackett, 1996). This paper will give the definition of software requirements; how they are determined, specified, documented, and who is included in the process of requirements; and the roles these individuals play in processing requirements. The end of this paper will bring all of these concepts together to help explain why these processes are extremely important.

In this semester, we covered three SDLC’s waterfall, incremental, and integration. The waterfall model divided the process of software development into different steps and the next step could not be initialized until the current step was completed. Incremental development was more of an agile development, since the processes could interleave. Integration development relies heavily on reusable code, which focused into integrating the components into the system. GCC and CLANG strive to give users the latest and most recent updates of their compilers. Therefore, with both being updated so frequently, the waterfall model is not the best SDLC for either of these systems. However, GCC or CLANG could be either incremental or integration. Both

The debate about what and how the software requirement specification (SRS) should be made between customers and contractors or suppliers continues. Also most computer science engineers and researchers agree that, software requirements specification permits a rigorous assessment of requirements before design can begin and reduces later redesign. It should also provide a realistic basis for estimating product costs, risks, and schedules [1], in other words, the SRS is the step that one would use to find the path to getting one’s own goal. Since there is not a standard for the SRS [14], it is necessary to find the hidden pattern for both the people who is making the SRS and the people who is reading the SRS. Furthermore, in software design engineers can refer the SRS as a part of larger problem solving process which encompasses problem determination and generates the solution for the problem. Thus, researchers consider that it is highly possible that the SRS can be classified under the problem solving cycle [2], which engineers will recognize the problem, re-define the problem in terms of making systems, develop a strategy plan to fix the problem, organize the knowledge of the problem domain figure out the resources that user’s disposal by listing functionalities, monitor user’s implementations, and evaluate the solution for accuracy. In SRS is unnecessary to follow the exact order but it is highly likely that completed one section with a problem another problem will pop up in

Software development is a process of building a good software with high quality. Software undergo development and changes to meet the different needs of user. Thus, software modifications, improvements and enhancements can be time-consuming and it may require too much hard work to cope with developing requirements. This maintenance and development can decrease the quality of software and may increase the internal complexity of software as well. One solution introduced to shrink the software maintenance effort while maintaining the software quality is software refactoring.

For the effective product based methodology and for the documentation of software based systems Agile modeling is the best practice. Whereas agile modelling is collection of the values and the practices of the software modelling which can he applied in a software development project in a most effective manner. I would like take this paper as medium and discuss the goals and the scope for the Agile modeling. The main concentrations is about the two approaches of software development i.e Agile Model driven development (AMDD) and the Test-Driven Development (TDD). And also the steps of the software development topics are discussed.

Today Software engineering is the most promising and advanced fields in the market. So certain methodologies should be applied to make it a persistent and ever developing in the coming future. This term paper mainly concentrates on the Case Methods, which provide not only knowledge of software engineering but also the problem solving and thinking ability among the practitioners. Introducing the concepts of software Engineering in Educational institutions creates awareness among the students not only with the knowledge of the subject but also the problems faced in the real world, which further reduces the burden when they enter the software industry. This paper focuses on features of Case Methods, their importance and benefits to individuals who practice them.
