ABSTRACT: During the past fifty years, some new software development approaches were introduced according to software development companies. Most of software companies try to produce valuable software in short time period with minimal costs and changing environments. Agile is one of them which are use in software development companies. This paper presents a review of agile methodology and describes the differences between them and when we use them. This paper also discusses problems in other Software Development Approaches, How Agile Discovered and why Agile Development Approach is best or why we use Agile Development Approach Analyzing, documenting, and checking requirements are important activities in all development approaches, including …show more content…

Software has merged into many diverse fields, and is becoming more complex. Changing requirements from customers is making it even more difficult. Old software development approaches are not able to satisfy the new requirements of the market in the best way, anymore. As a result, new software development approaches are evolved, as agile methodologies, mainly to solve such problem. The new methodologies include modifications to software development processes, to make them more productive and flexible. 2. Problems of Software Development Approaches There are many problems in other Software Development Approaches Some of them are following. • Evolving requirements: Most of the customers do not have a clear vision about the specifications of their requirements at the early stages. Some customers realize what their true requirements are only when they use an application that does not really meet their needs. • Customer involvement: Lack of customer involvement leads to higher chances of project failure. Many companies usually do not allocate any effort for customer involvement. • Miscommunications: one cause of the misunderstanding of requirements is the miscommunication between developers and customers. 3. How Agile …show more content…

in the mid-1990s. It is an outgrowth of, and extension to, Rapid Application Development (RAD) practices. The first two phases of DSDM are the feasibility study and the business study. During these two phases the base requirements are elicited. Further requirements are elicited during the development process. DSDM does not insist on certain techniques. Thus, any RE technique can be used during the development process. DSDM’s nine principles include active user involvement, frequent delivery, team decision making, integrated testing throughout the project life cycle, and reversible changes in

    The agile approach is based on the idea that change can be of value to the client. The details of the project, the scope of it, are defined as far as value for the client is known. This makes the delivery of value to happen in a short time. And by receiving constant feedback, project progress will be achieved. This will lead to having a result that satisfies the client and not a result that will satisfy what was specified at the beginning of the project. To be able to see these changes as something positive and of value to the client, a more proactive organization is required (Owen, Koskela, Henrich, & Codinhoto, 2006).

  • Exploring Software Development Methodologies: From Waterfall to Agile

    Consequentially, the Waterfall consists of seven procedural steps followed in linear order, but possess small gates where information, specifications, and designs are reviewed. The seven procedural steps performed by software companies, according to Lotz (2013): “1. Gather and document requirements, 2. Design, 3. Code and unit test, 4. Perform system testing, perform user acceptance testing (UAT), 6. Fix any issues, and 7. Deliver the finished product.” However, the Waterfall methodology clear and defined linear plan provides development teams distinct guidelines for each phase of development, but the methodology still possesses pros and cons for usage. The advantages of the methodology are discipline provided by the procedural phase structure, current phase of the development team easily identifiable by vendor and client, and provides efficient knowledge transfer between team members. (Melonfire, 2008) Furthermore, the associated disadvantages of the methodology are the phases are not flexible to change, developers cannot return to a previous phase, and originally develop designs are not feasible. Finally, the trait of not being flexible deems Waterfall appropriate for well-defined projects, and projects with a fixed-price, a fixed-timeline, and a none adjustable scope. (Base36,

    The characteristics of AM are that they the value “(a) individuals and interaction over processes and tools, (b) working software over comprehensive documentation, (c) customer collaboration over contract negotiation, and (d) responding to change over following a plan”[1]. AM concentrate on developing functionality over managing the development of functionality. The management of traditional software projects favors a well-planned approach – typically called the “waterfall approach” – documenting all project details before development starts. AM advocates creating a high level design of the whole system, then working on functionality in ascending order from highest to lowest in customer perceived business value. All AM assume requirements will change constantly so shorter development cycles are instituted to accommodate for the new or changed requirements. AM also assume close contact with the business (for the purposes of this paper, business, client, & user are used interchangeably) to answer any questions, and help resolve issues related to design, cost, and scheduling.

    Given the time, it takes to develop large sophisticated software systems it not possible to define the problem and build the solution in a single step. Requirements will often change throughout a projects development, due to architectural constraints, customer’s needs or a greater understanding of the original problem. Iteration allows greater understanding of a project through successive refinements and addresses a projects highest risk items at every stage of its lifecycle. Ideally each iteration ends up with an executable release – this helps reduce a projects risk profile, allows greater customer feedback and help developers stay focused.

    When projects fail they usually result in a large financial hit for the company. According to Building Competitive Advantage Through Project Management, “the role of project management to competitive advantage is inherent in the number of projects completed on time, on budget, and within scope while meeting the project objectives.” Organizations that are able to complete project on time, on budget, and within their scope are the ones who have a competitive advantage over their competitors. Using project management techniques often leads to an overall higher customer satisfaction because the organization is able to compete projects and focus on their

  • An Evaluation Of Requirements Engineering

    1478 Words  | 3 Pages

    As more companies that are leading technology are transforming from the traditional waterfall development model to an Agile software methodology, requirements engineering provides a process for software engineers to understand the problems they need to solve (Martin, Newkirk, & Koss, 2014). It is of key importance to understand the customer 's wants and needs before beginning designing or building the computer-based solution, as developing a solution that ignores the customer’s needs provides value to none of the parties involved. Thus, the intent of requirements engineering is to produce a written understanding of the customer 's problem (Pressman, 2010). Work products that are available to communicate this understanding include user scenarios, function and feature lists, analysis models, and specifications. This paper provides an evaluation of requirement patterns, an assessment of problem solving techniques most effective, a descriptive explanation of the patterns that includes a visual taxonomy, and an explanation of how the patterns identified are related.

    In the continuously growing field of software engineering the new paradigms are being introduced day by day to enhance the efficiency of software development process. Continuously new and better ways for developing software application at small business or at enterprise level are looking for. In cost reduction and fast delivery the Lean Software Development (LSD) is attracting the industry. A lot of study and research is being conducted in LSD as it is still in evolving process. Recently “from agile to lean” agile software development using lean principles has been given noticeable attention. However a complete development cycle fulfilling all the lean principles has not been proposed yet. To introduce a new “Lean” development model consisting of all the development phases is the state of the art of the research. The aim is to propose a new Life cycle model; a complete cycle with high goals and requirement tractability as well as requirement change control. Specific to lean development the model will be based on other software engineering models. It will be used for two main purposes; the research and its practice in real world and use as a model to develop software that will be opera table. Efficient model by reducing the time and controlling project cost in continues maintenance process is the goal of research. The unnecessary delay in whole development be reduced is its working efficiency. To deliver the project faster, to increase the maintainability and efficiency during and after the development of project the model will be developed.

    Management development can be emphasized separately, as it is similar, but in some issues quite different process from common training and development process. Management Development is a systematic process which aims to ensure that an organization has the effective managers it requires to meet its present and future needs (Armstrong, 2001). Management development is concerned not only with improving the effectiveness of individual managers but also with an improvement in management performance as a whole and organizational effectiveness. The process of management development should be related to the nature, objectives and requirements of the particular organization; there needs to be effective human resource planning present (Mullins, 2007).
