Optimization Of Software Based Systems Agile Modeling

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.

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.

Agile Project management is one of the industries dominating methodology for project management in IT. It is an incremental and iterative way to manage the build and design activities for constructing an IT product, services, and project development in manner which is highly interactive and flexible. In this methodology, scope is defined in granularity that is appropriate with time horizon and checked with the agreement on each feature with the customer. In this methodology work steps are divided with feature breakdown structures. In order to track the progress of the project progress charts are used instead of Gantt charts. Cross-functional and test-driven development teams starts working from the very beginning of the project to provide

Using the Agile approach enabled us to organize the software project into chorological order from the User Requirements to the End product. The requirements were formed by meeting our client Fernando on regular bases discussing the requirements of the program. He would assure

“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.

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.

Agile is an iterative and incremental (evolutionary) approach to software development which is performed in a highly collaborative manner by self-organizing teams within an effective governance framework, with "just enough" ceremony, that produces high quality solutions, in a cost effective and timely manner which meets the changing needs of its stakeholders [1].

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 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.

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

This paper discusses about Traditional Software engineering, Agile software development, the Waterfall software development model and also a new concept of Agile software engineering. After a thorough analysis of the paper, I could relate it to topics of Traditional Software Engineering (TSE) which is the process of developing software products. It deals with Cost estimation and budgeting, scheduling, Requirements analysis, Design, Implementation, Testing and Deployment, Measuring products and processes, Quality improvement, Maintenance and so on… Another concept that I could relate to was

Agile Development Model is also a type of incremental model with focus on process adaptability and customer satisfaction by rapid delivery of working software product. Agile methods break the product into small incremental releases with each release building on previous functionality.

In general, attributes of successful Agile implementations include the following aspects small teams ,customer feedback, continuous planning ,co-located and cross-functional teams

First of all, here is some brief description about Agile development model and Waterfall development model. Agile development model is a type of Incremental model which means the software is developed in incremental and rapid cycles. This results in small incremental releases with each release building on previous functionality. Software quality is ensured to maintain well by testing each release thoroughly. It is usually used for time critical applications.

Software development is one of the highest demands in all over the world. We use software development techniques to solve the problems and to satisfy customers. Agile software development is a conceptual framework for software; it is also a group of software development methods based on iterative development. In 2001, agile software development was created by seventeen people with a desire to find alternative approaches to software development. The most important thing about agile methods are team work, conveying information to the team, face to face conversation, and satisfy the customer. There are various methodologies but I am going to describe the most popular ones.
