The Agile manifesto is mainly based on 12 principles with key emphasis on Customer satisfaction, ability to accommodate and reprioritize the requirements, good team coordination between business users and developers, sustainable and iterative productive releases in short development cycles. Though we have various methods that fall under Agile methodology umbrella and share common characteristics and practices from the implementation stand point, the terminology and tactics that are followed under these are different. Some of the methodologies that fall under agile umbrella are 1. Scrum is one of the light weight methodology which is broadly used in managing and controlling iterative and incremental projects where product owner plays a key role by working closely with the Product team.
These methodologies impose various degrees of discipline to the software development process with the goal of making the process more efficient and predictable. For the purpose of discussion in this paper, SDLC methodologies are divided into two groups traditional and lightweight.
The following introductory sections describe the problem to be investigated and the goal to be achieved.
They are considered light because of the reduced documentation and managerial effort required. The goal of this paper is identify the strengths and weaknesses of these new lightweight methodologies and to make recommendations for their effective use.
The paper begins with an overview of traditional SDLC processes. Format This research paper is a descriptive study formatted in five chapters. This is followed in the second chapter by a review of the literature relevant to the problem. In the third chapter, the research methods and online tools and resources employed during the completion of the paper are described.
The fourth chapter presents the results of the research and provides an analysis of the strengths and weaknesses of lightweight methodologies.
The fifth chapter begins with a summary Agile development methodology essay traditional and lightweight SDLC methodologies. This is followed by recommendations for the effective use of the new techniques.
Finally, the paper concludes with an overall summary. Summary SDLC methodologies have recently gone on a diet in order to better meet the requirements of many software projects. In the following pages, this paper provides a review of literature relevant to this trend, a description of research methods employed, results of the research, recommendations for effective use, and an overall summary.
Chapter 2 Review of Literature The literature review that follows is organized by subject heading. Included in the discussion of lightweight methods are nine currently used models. In their journal article, they related how the use of traditional software development models is numerous and often regarded as the proper and disciplined approach to the analysis and design of software applications.
Examples of such models included the code and fix, waterfall, staged and phased development, transformational, spiral, and iterative models. The authors also described how traditional SDLCs have the same goal and are similar in the approach they use to achieve it.
A related article by the U. It further defined a quality system as one that: SDLC is traditionally made up of several phases, each comprised of multiple steps. These steps typically include software concept, requirements analysis, architectural design, coding and debug, and system testing.
Osborn also discussed traditional SDLC techniques and how over time the phases of these approaches have become enshrined in a development cycle that includes: Each phase of the development cycle is strictly sequenced.
For example, in the waterfall model, the output of all prior effort is a prerequisite for subsequent steps e. Lightweight SDLC Methodologies In response to traditional approaches to software development often viewed as cumbersome and bureaucraticnew lightweight methodologies have appeared Fowler,December.
Light SDLC techniques are a compromise between no process and too much process. In the following sections, literature related to nine types of lightweight SDLC methodologies is discussed.
His work with traditional predictive methodologies led to the conclusion that they were inherently flawed, in particular when applied to modern business processes. In response, he offered a new approach, Adaptive Software Development ASD as a framework from which to address the rapid pace of many software projects.
ASD is grounded in the science of complex adaptive systems theory and has three interwoven components: In contrast to the typical waterfall plan, build, implement or the iterative plan, build, revise life cycles, the adaptive development life cycle speculate, collaborate, learn acknowledges the existence of uncertainty and change and does not attempt to manage software development using precise prediction and rigid control strategies Highsmith, The process is mission focused, component based, iterative, timeboxed, risk driven, and change tolerant.
Although the final results may be fuzzy in the initial phase, the overall mission is well defined. In addition, adaptive lifecycles are component based in the context that a group of features are developed i. Lastly, adaptive lifecycles are risk driven and change tolerant Highsmith, Similar to the spiral development model, adaptive cycles are guided by the analysis of critical risks.
In addition, ASD is tolerant to change. The ability to incorporate change is viewed as a competitive advantage not as a problem. The benefits of ASD include the following Highsmith, Agile methodology is an approach to project management, typically used in software development.
It refers to a group of software development methodologies based on iterative development. Requirements and solutions evolve through cooperation between self-organizing cross-functional teams, without.
