The author of the article mainly discusses about the two approaches that are useful for Software engineering.
As technology is increasing on a rapid scale there is much need for the different software development approaches to be modified and enhanced in order to face the present customer requirements and blooming Technology market. Believers of the old approach of software development finds its best in developing with planning, reusability, predictability that helps to develop a perfect software product. On the other hand trending designers likes another model of software development that is Agile Methods, both the plan-driven approach and the agile methodology has their own pros and cons. If combined and developed a good end product can

XP is one of the agile methods which is defined as Extreme Programming, many new developers and designers are tending to follow these methodologies than the age old techniques. But managers who are accustomed to the traditional way of software development are finding it difficult in accepting these new approaches. Furthermore the plan-driven approach also has many underlying advantages such as focusing on the major goals of the project which is named as “major milestone” on the contrary to “micro milestones or inch pebbles”. In the plan-driven approach more planning is emphasized which pressurize the development teams to follow the pre specified documentation even at the minor levels of modification at technology, commercial and personal aspects. The author of the article suggests that there should be at least three milestones in the software development process. Firstly for the progress of the project in order to know the current status of the project. Secondly for the stakeholder’s checkpoint i.e. to check the progress on the development process form the stakeholders point of view whether the commitment given to them is fulfilled or not. The planning spectrum demonstrates the models on straight line where the unplanned hacking is on the left of the spectrum and the inch pebble in on the extreme right.
Now after brief discussion of the different approaches the author tries to explain the advantages and disadvantaged of both
Objective of this research paper is to learn and understand the recent changes in software engineering and how it can pave way to an advanced method of software engineering in the coming future. Hence this paper will be based on how current trends in software development would affect the future.
Similarities and key differences in theory, practise and value base between the two approaches will
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
In order to achieve successful results within established time-frames and budgets, project managers are likely to employ methodologies models. A project methodology is a model that aids managers to plan, design and implement their project goals. Project methodologies are helpful to project manager in any field, for instance, Niel Nickolaisen CIO at the Western Governors University, is an advocate for the agile software development methodology. As these models grants flexibility when dealing with stipulations and scope changes on a project. Needless to say the agile software development methodology is just one example of a varied assortment of methodologies, each with their strengths and weakness. As such, it is up to the project manager to decide which methodology fits their needs, as there isn`t a one fits all solution.
“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.
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.
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
Both methodologies conduct the same activities such as, define, gather, analyze, design, test, implement and maintain, just in different styles.
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.
The purpose of this report is to define and discuss the use of agile methodologies. Agile is becoming a more popular term within the information technology industry and this report will help those unfamiliar with its techniques understand how agile works. The goal is also to inform the readers why agile can be preferred over traditional methods. While reading this report, it is recommended to keep in mind that agile is an alternative to using the traditional systems development lifecycle method.
It is very important to delivery software faster to the market and in most sophisticated manner. Agile has provided a promise faster to market and allows customer collaboration and agility to take change in requirements which facilitates development and delivery of product which is more up to date with stakeholder requirements.
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].
Both these approaches have their own pros and cons and both are widely used across the globe and across industries. There are many factors that need to analyse before choosing which approach is most suitable for your project needs and objectives. These factors are following but not limited to
In conclusion, agile software development is a very exciting and useful approach, although some project suit agile more than others. The collaboration and visibility can provide a much better and rewarding experience for the team to develop software products. Over the last years, many companies dramatically improved their performances
