Essays on Waterfall

The delay problems arose from the failing of the software. A system that worked well with one team or one project could easily fall when used on a different team. The waterfall approach was also to blame for the delay problems. The system relied on the mass launch rather than a sequential launch of the software (Bright pg 2). Why has the Waterfall Method "stuck around"? i.e. why is it still in use? The Waterfall method has stuck around since waterfall method mostly offers the stepwise approach to any problem. It shows the developers the steps and the ...

Constructed from 1935 until 1937, Frank Lloyd Wright’s House on a Waterfall-Fallingwater in Mill Run, Pennsylvania, Edgar J. Kaufmann House is at once highly-functional, and aesthetically-pleasing. Its cantilevered stone slabs lend the house a naturalistic “feel”, as it appears to be a part of the slowly-descending waterfall. Upon initial viewing, it appears to defy gravity because of the cantilevered slabs. Not only does the design echo simple, horizontal Japanese lines and forms, but it supplements the rocky terrain, adding an earthy, harmonizing element to the overall aesthetic (moma, 2004, internet). Functionally, it is somewhat unsettling that the cantilevered ...

Agile , which means “the quality of being agile, readiness for motion, mibleness activity, dexterity in motion” is an alternative to conventional project management providing solution for light and fast software development required by business community, especially with rapidly developing Internet and mobile software areas (Abrahamsson et al. 7-17). Agile movement in software development possesses four core values. First, close relationship in a team of developers is much more important than processes and tools. Second, the most important goal for software developers is regularly release tested and improved software. Third, the emphasis is put on cooperative relationships between developers and ...

Introduction

There are two methodologies that are usually adopted in the management and implementation of software development projects, namely the waterfall and agile methodologies. In the waterfall method, the project development is conducted in a linear or sequential manner where each development phase has a distinct goal (“Waterfall Model,” n.d.). This means that the project development moves to the next phase once the current phase is completed and that it is not possible to go back to a previous phase. On the other hand, the agile methodology addresses unpredictability and complexity through iterative and incremental cadences termed as sprints (“Agile ...

Introduction

The world never saw a rainbow until long after most of the Gods on Olympus and the heroes of the land were tales told by grandmothers to the eager faces of their grandbabies looking through sparkling eyes looking at the old but still beautiful face of Chloe. Her strong but soft voice filled the quiet room aglow with the golden and orange light from the warm crackling fire at the hearth in the main room of the small but clean and welcoming house on the hill along the cliffs overlooking the Aegean Sea. Chloe loved telling these old tales ...

Data gathering is a significant process that is fundamental to the process of developing information systems. With the fact that there are different information systems that are in use, the ways and methodologies that are used in gathering the data is also seen to be different. Data gathering process for a data warehouse is different from data gathering for operational systems. The difference is that the data gathering for operational is done is such a manner that there is support for transaction processing (Peña-Siles, del Mar González-Zamora, & Machuca, 2012). The data that involves the transactions that are being undertaken are ...

- What is Agile and what are user stories? Agile refers to a software development methodology that provides more efficient ways of handling and managing software development projects as compared to traditional methods such as the waterfall development methodology. Agile development allows for the evolution of requirements and problem solutions through the collaboration of cross-functional teams. The methodology promotes evolutionary development, adaptive planning, continuous improvement, early project delivery, and promotes rapid response to change. Agile has some unique characteristics and emphasizes more on interactions than development processes and tools. The methodology also places more focus on delivering working software ...

<INSTRUCTOR’S NAME> <COURSE NAME>

The agile and waterfall process are two distinct project management methodologies. Waterfall process follows a sequential design that includes various phases. These phases include conception, initiation, analysis, design, construction, testing, implementation and maintenance. Since this is a sequential plan, a project team cannot execute an analysis phase without going through conception and initiation phase. Similarly, once finished with a prior phase, the project can no longer go back to it. On the other hand, the agile process follows an incremental approach. Developers create a simple design and begin to work on minute modules. These development of ...

Software Engineering Life Cycle Models

In software engineering, a life cycle model is a framework that describes the activities that will be carried out during each phase of software development project. The discussion will focus on five software development models namely: the waterfall model, the spiral model, the v-shaped model, the iteration model, and the structured evolutionary prototyping model.

The Waterfall Model

This model is linearly sequential, resembling a series of cascades. It involves the following phases; establishing requirements, designing, implementation, testing, installation and maintenance. Each stage of this model produces a deliverable that is required by the next phase and the deliverable has to be completed before beginning the next ...

SDLC acronym stands for Software Development Life Cycle. A SDLC model provides a standard for planning, organizing and executing a software development process (Maheshwari, 2012). It involves phases like project initiation, requirements gathering and analysis, design, system specification, programming and testing, installation and maintenance, and phase-out. Two main approaches to SDLC depend on whether the projects can (predictive approach) or cannot (adaptive approach) be planned out in advance. - Waterfall Model: Each phase is completed in sequence and then the results of a completed phase flow into the next phase. There is no going back once the phase is completed. The ...

Methodology in software project management means a standard practice that sometimes with guides and procedures on how to carry out activities. Methodologies are sometimes diagrammed to illustrate procedures that project team members ...

Incremental model can be said to be an enhancement of the waterfall model. There are several waterfall approach done repeatedly in the development of the software. The software development cycles are split down into smaller pieces that are easily managed. Each of the iterations or the software version released go through the whole waterfall steps; requirements, design, implementation and testing phase (Pressman 52). Each iteration produces a working version of the software which is then tested. The software version is tested by the users and the developers to capture the misleading or misunderstood requirements. The following software development or ...

In software systems development there is usually two approaches considered. These approaches include the traditional methodology (waterfall) and agile methodology. Both the methodologies have advantages and disadvantages.

Traditional/Waterfall Methodology

“It is a method that has been in use since the 1970s and is still in practice. It’s is often considered as a classic approach to the life cycle of systems development.”. It is of a rigid kind and the development is linear where each process/phase of development leads to the next. This method of system construction is similar to; - Requirements Analysis - Design - Implementation - Testing ...

Visual loss due to cataract is due to clouding of the lens of the eye leading to the inability of light to pass through it and focusing on the retina in the back of the eye (Jacobs, 2013); the vision loss can be partial or complete in the affected eye. The Latin word “catarractes” means waterfall; to someone looking into a persons eye that suffers from cataracts the clouding looks like the splashing water of a waterfall. It is the leading cause of blindness worldwide.

Abstract

Some definitions have been given to tell what software testing really is. It’s not universally acceptable that this is the real definition but it shall be adopted and used for this paper. Software testing can, therefore, be defined as an enquiry into the quality and reliability of software before its adoption and consequently its use. It’s a procedure that allows the potential and more so intended users to make decisions on whether or not they are to adopt the software. This process gives unbiased views on the credibility of the software that is also objective. It covers both ...

Software development is a process that involves numerous procedures and consists of certain important stages. Due to its complicacy, it is reasonable to make use of some models that allow for making the process of development the most productive. If the most appropriate model is chosen, it will also allow for costs minimization and reaching the initial goals. Waterfall model is one of the most popular models known and widely used today around the world. It was first introduced in 1970 by Winston W. Royce and since then it has undergone a number of changes that keep it up-to-date and ...

Unlike the classic art, which was full of expressive and definite beauty and meaning, contemporary art is sometimes difficult for understanding. Artist’s idea might be hidden so deeply within avangardist images that it might be even impossible to follow painter’s idea. Julie Heffernan is definitely not such kind of artist. She is one of those very few painters who manage to unite the classic images of beauty with the symbolism of modernity. Julie Heffernan is famous for her series of paintings, in which refinement and idealism of baroque is combined with symbolism of contemporary reality. Another characteristic ...
