Advantages And Disadvantages Of Scrum Implementation

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.

“Agile” was first introduced in 2001, by a team of software engineers looking to improve their adaptiveness and responsiveness to ever-changing requirements. Not knowing where to begin, the team began by formulating principles, which they would use to guide their new development process. Which, in turn, lead to the creation of the Agile Manifesto, and thus a new methodology was born.

A detailed analysis is needed before writing a user stories, and they are required to revised and revisited to check whether they are valid or not. It lost the details of performance requirement. The user stories do not define the user interaction details with the system. In the designing phase, there might be some of the gaps in the requirements like identifying some of the missing user stories, and mis-estimated stories. Some of the user stories are less relevant. The user stories lack with the level of detail and they are dependent on acceptance tests. They are difficult to put in a large and complex projects. While implementing the user stories in a project a frequent client interaction needed to be

Now that I have explained the processes and practices of extreme programming I want to relate some of those practices to explore adopting the XP methods, advantages found, and some failures that can occur while using

I personally really like Agile, and I have worked very well in teams using Scrum. Yes, we did have problems too, customers with bugs and we also fell behind on the schedule sometimes. But applying Scrum correctly has allowed us to be informed, committed and react quickly to those issues. Everybody in the team is in sync and knows what to expect, stakeholders feel informed and involved, and you can measure progress and forecast releases with a certain degree of certainty. All this with what I would consider very little friction, bureaucracy and with what I would consider a short learning curve, especially compared to other methodologies and frameworks such as Rational Unified Process (RUP).

The paper compares two Agile methodologies known as Extreme programming (XP) and Feature-driven development (FDD) and explores the effects each has on games systems.

how they should be applied, none have used project data to clearly conclude which one is

Agile techniques should be used to solve the current issues faced by the company as agile techniques normally being used by the software industry help the business to act in response under the unpredictable situations faced. In Agile methodologies opportunities are been provided to evaluate whether the project is under the direction all through its development cycle. All this is being accomplished with the help of regular tempo kept in work, and the teams must show a product which is having the desired potential.

their teams by defining, disseminating, and sustaining a vision that influences the internal models of individual agents. The Agile Manifesto (www.agilemanifesto.org) created in 2001 by the proponents of these methodologies articulated a core set of values useful in steering this vision. Simple rules. In CAS, agents follow simple rules, but their interactions result in complex behavior that emerges over time. The standard XP practices represent a set of simple rules for agile development projects. They’re accepted by all members of the team at the outset, though the team can adjust or add new practices as needed. Throughout a project, the manager identifies practices that aren’t being followed, seeks to understand why they’re not, and removes obstacles to their implementation. XP practices provide simple generative rules without restricting the autonomy and creativity of team members. Free and open access to information. In CAS, information about plans, progress, objectives, and

The organization understood the agile methodology would help reduce development costs and reduce burnout because the team would not be putting in long hours for long periods of time to work the project. Additionally, the developers could be working to develop software at the same time the business requirements were being gathered and reviewed. One process that the team was working on did not impede the progress that another area of the team was working on. The agile methodology empowered our team to continuously plan and re-plan throughout the entire development processes.

This paper describes Agile development methodologies and their benefits. Section II presents key elements of Agile. Section III presents benefits of Agile development methodologies over traditional waterfall methodologies.

Most of software houses use agile development methodologies such as XP and scrum to enhance its product quality, increase communication between teams, release products in short time and to participate its clients in software development life cycle. There are many problems usually occur, first problem the time spent between development of the software and to make it operational. Second problem is the difference between environments. There are two different environments; development environment is the first environment which is used to develop, build and deploy the software in development life cycle. This environment has no constrains. On the other hand, operation environment, which is usually called production environment. In operation

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).

Agile methodologies provide businesses with a way to quickly react to changes in their environment. By delivering small portions of code over the course of a few weeks, developers can provide end-users with useable functionality on an ongoing basis as they move closer to the goal of providing the complete software. By being more reactive to changes, such as new requirements or changes in priority, agile allows development teams to be able to be more responsive and to provide customers with revised applications that are based on feedback that they have previously provided. Agile models, such as XP, are geared towards cost savings
