Optimization Of Software Based Systems Agile Modeling

Agile methodology is an approach to project management and agile software methodology is not a one methodology but a set of methodologies which share common characteristics to achieve business goals. Before 1950’s project management have taken place in an informal way for many eras and after an ameliorating of formal project management methodologies began to be defined and swiftly spared through the industry rather than traditional methodologies. The traditional approach of project management identified a set of sequences of steps to be completed such as initiation, planning and design, execution and construction, monitoring and controlling and completion but not all projects will have every stage and some projects can be terminated before they reach completion. When it derived to IT industry in the past few years there’s been

Agile team tries to build a product that meets the customer’s intent rather than the detailed description provided in the traditional methods, thus in the Agile PM customer becomes one of the team guide and member.

In this paper we develop a new model for software development that lays special emphasis on highly structured lifecycle and defining an output with each stage and also tries to fulfill the objective of the Software Engineering of developing high quality product within schedule and budget. The new proposed model is designed in such a way that it allows client and developer to interact freely with each other in order to understand and implement requirements in a better way using the concept of process model.

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).

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.

First, let’s take a look at Agile, in particular the role of scope. Several traditional software development models came about in the 1960s, such as incremental, spiral and waterfall modelling. Over time it was realized that the software development team did not realize all of the needs up front. Thus, the customer was was not delivered what was expected. It’s essential to have an outline of who, what, when and where but this is often a transforming list.

The Agile Methodology Principles makes the development much faster because the primary importance is given to the customer satisfaction and continuously delivers product. Even though requirements change at the ending phase the product is developed. The Agile development insist the self-organizing team which can create requirements, best architectures, best models. The Agile development promotes a distinct way of thinking to build things and methods to deliver continuous improvement of product. It facilitates to make best practices and decisions together. It a development to promote the adaptive planning, continuous improvement, evolutionary development and delivery, and required time to complete work. It encourages for rapid response to change in the whole development cycle. The project team prefers agile development to move in a creative and quick way. The project progress also depends on working software and project environment and support is provided and built by the individuals. They promote the sustainable environment. Constant attention is provided to the technical excellence and best models are given by the agile methodology. This principle helps the project team members

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.

The agile methodology with scrum-based approach has worked effectively for our organization because it is flexible and iterative with continuous feedback and constant communication and favored by frequent and short delivery schedules (Chang, 2010). This approach brings about a high level of competence and high level of motivation to work. It also instills discipline and respect for time by

Agile values Individuals and Interactions over Processes and Tools. Agile emphasizes the importance of individuals having interactions and engaging in collaborative thinking for software design and development.

In agile projects, various stakeholders (IT and Business teams) need to collaborate to share information and clarifications for common understanding about the various type of changes in various stages of the project. If IT and Business teams don’t collaborate regularly during the project, then it is difficult to identify and manage the various types of changes (i.e. requirement changes) that can come up during the project. Effective collaboration is very important when there are changes in the project {Maruping, 2009 #2416}. A weak IT -Business collaboration is an agility inhibitor in software development {Vidgen, 2009 #2414}. This collaborative decision making approach among various stakeholders is necessary for anticipating and responding

Agile methodologies promote a structured project management process that encourages self-organisations, accountability and teamwork. These are the best practices that allow customer needs and company goals to be developed through rapid delivery of high quality software and a clear business approach. The software development is based on iterative development that consists of various procedures (cPrime, 2016).

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.

In 2001 a group of thought leaders recognized the need for common set of values and principles that represent Agile Vision, as traditional development methodology was failing too often and they came up with Agile Manifesto that emphasizes four important Agile
