Notes On Trade Offs And Software Development

So, there is an urgent need to reduce the time spent on working by each employee with the project work. This can be done with the help of introducing a proper software development process and implementing it successfully.

Introduction to Agile Methods by Hayes and Andrews gives detailed-oriented information about different aspects of agile methods like why there is a need for new software development processes and pitfalls of traditionally methodologies and how this lead to emergence of agile methods. They describe various existing agile methods but describes only one in great detailed – Extreme Programming(XP). They define Extreme Programming as agile, adaptive software methodology having well defined values - Communication, Simplicity, Feedback, and Courage. Failing in achieving this values will result in failing Extreme Programming. Extreme Programming is used only when you have complete understanding of the business and requirements. Extreme Programming follow a series of iteration to deliver the final project. Initially the story heard from the customer is broken down into smaller stories such that the developers can assign time to develop that stories and then its deliver to the customers for feedback. Coach plays a vital role in Extreme Programming. Afterwards Hayes and Andrews describe how XP differs from traditional methodologies. They also explain the common misconception about Extreme Programming is spread around the world. There are only fewer companies in the world that uses Extreme Programming because people are afraid of changing to new methods.

One of the initial steps in researching a problem is to know exactly what the problem is and compose a problem statement that unambiguously identifies and defines the problem to research. Sekaran (2003) said, “No amount of good research can find solutions to the situation, if the critical issue or the problem to be studied is not clearly pinpointed” (p. 69). The area of research for this paper focuses on software development, in particular, the study of agile software development methodologies and if these methodologies are successful in delivering software on time, within budget, and includes the requested features.

Successful projects where software engineering methods have been applied include Linux, the space shuttle software, and automatic teller machines. When it is cheaper to run a business or

The cost of changing program doesn’t change over time as extreme programming follows some of the practises like getting feedback from customers, coding and testing frequently and eliminating defects early, and Involving customers in every stage of development

Software developers make effective software. It is an engineering endeavor that cannot be extracted from the context and systems with which it interoperates. The heart of a good software solution is not in turning the functional specification into code but rather in the use of available resources such as

In the software industry, it is common place to find large and very complex software system development projects with the number of individual requirements expected from it running into the multitude of thousand many times. There are usually more requirements than you can implement in the allocated stakeholder’s time and resources. The software solution that the customer has in mind and wants to be in place cannot be delivered in a single release. Even if it could be done, it would be a very costly affair which would eat away a lot of time and pose greater risks due to the nature of the ‘big bang’ approach one has to follow to implement it. Further, there will also be restrictions in the form of capital and time from the stakeholder or

Yet another method is extreme programming (XP). It is also a software development method which improves software quality and responsiveness to changing customer requirement (extreme). This program has proved very successful at many companies. It is successful because it focuses on customer satisfaction. Extreme programming emphasizes teamwork. In this program, managers, customers and developers are all equal partners in a team. Extreme programing improves a software project in different ways which are communication, simplicity, feedback, respect and courage. In this method, programmers constantly communicate with their customers. They keep their design simple and clean. They get feedback by testing their software and deliver the system to the customer as soon as possible and implement changes as suggested. Every team member involvement is essential for the success of the program. With this foundation extreme programmers are able to courageously respond to changing requirement and technology (Extreme Programming).

Abstract- In software designing every phase consume some resources and some cost which is associated with these resources. In every case the cost of software is vary with the development duration of the software. The most important work done by the project manager is to maintain the balance between time

In recently years, With the developments of software industry and rapidly increased requirements for software developments, hundreds and thousands of software development organizations and companies set up

Software is the base necessity in a system as it acts as a guide between the user and the system. Programmers design different kinds of software by writing a complete set of written instructions that enables the system to obtain the request instructed by the user. However, with the increase of technological improvements, businesses are now looking at software development organizations to design cost effective, high-quality, and adaptive applications to meet business objectives. Software businesses can run into a variety of issues when creating, changing, or updating the software that they have designed for their clients. For instance, a programmer could make a small change to an application causing a ripple effect with endless updates

“Software engineering is like an art in that it begins with a problem and ends with the creation of a solution that solves it (Blum, p.9).” Engineers grew out of the ashes of the problems of the world. Software engineers deal with problems and maintenance in computer software. For a computer to find a solution to anything, programs have to be designed and written into the computer using models for the software process. Bernd Bruegge, in his presentation titled, Software Lifecycle Models, states “a software process represents all the phases needed to create a program, from the study of the goals leading to the objective, to the maintenance of said goals and how the phases relate to one another.” There are many different models used as guidelines to form the software process needed to create a program, but this paper will prove how the waterfall model performs the software process in the most reliable and user-friendly fashion. The waterfall model will be defined and then compared to the V-model, prototype model, and Boehm’s spiral model, with all aspects in relation to software engineering.

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.
