Change Of Software Development Process

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 project management lets software project managers and employees alike adapt to changing circumstances, rather than try to impose rigid formal controls, as in traditional linear development methods.

In the year 2000, a new agile methodology started to gain traction worldwide called Extreme Programing. This methodology has the goal of improving the quality and decreasing the time it takes to complete the project [1].

Other methods include the waterfall, which is the traditional method and is almost become obsolete. This is because it was very expensive. It tangles the whole project and the team works in unity to accomplish the whole project. One mistake can drag the whole team behind, and it is difficult to debug errors. Feature driven method is another method which is costly because it focuses on providing the best of every part of the project. Process pride has a negative effect on timing and cost. Joint application development is the inverse of the agile software development strategy. It takes the project as a whole and work is assigned progressively without a work breakdown structure. It is good for very small software projects, but dangerous for lengthy software development projects (Kaufman, Perlman, & Speciner, 2002).

There are many different software development methodologies for a software project to choose from, each of them has their own pros and cons, which one is the right one for your organization. In this article, we will discuss the different types of project environments that are available, first we will start with the Agile methodology pros and cons and then we will talk about the suitability of the method with different project environments.

There are a few popular methodologies in software development. Agile and Scrum technologies are among the most mentioned and used ones. Agile is like a big father for a number of other methods including Scrum. The framework of Agile contains basic principles being a part of characteristics for different methods derived from Agile. Nonetheless, Scrum is quite independent and can be referred as a separate style of software producing management. That’s why the topic of this publication is agile vs scrum.

Agile method is relied on business involvement. It increased the responsibilities and burdens for business people. On the other hand, customers need to involve in agile method because agile method is based on the requirements that is given by customers. (Sharma, Sarkar & Gupta, 2012) Developers will usually hold a regular meeting for each deliverable, such as weekly meeting. So the team members can communicate and summarize their work. At this time, customers need to provide feedbacks on the iteration and they need to find out is there any changes are needed. (Yu, Loo, Tham & Tan, 2012) Agile method is focuses on

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.

The agile lifecycle based on experiment operation, which cause the good performance. The visibility indicates to support the product development. This provides efficient vision for key users. Risk management, a short incremental releases are visual to the product holder and product team through its development which help us to select any problems early and make it easier to reply to alteration. Agility indicates to admit the alterations, client satisfaction, creating the suitable product [6, 8]. There are agile methodologies: feature driven development, Extreme programming, rational unified process, animated systems development, scrum and Adaptive software development [9].

Yet unlike the methods that originated it, agile development is less confined and allows developers and teams to circumvent the red tape that more bureaucratic methods put forth. This newfound flexibility and freeform environment in agile development is feasible by excluding some of the extensive planning, detailed documentation, and defined cycles that are intrinsic to other traditional methods. This sort of approach deviates significantly from most traditional software engineering methods for many reasons. For example, unlike the waterfall method, agile development merges the testing and building phase as concurrent processes, speeding up the overall process. In ideal conditions Agile software development allows for earlier accessibility of software, gradual and iterative progress, and higher feasibility of change. However ideal conditions are not always the case in the real world. Due to the intentional reduction of analysis and planning, agile development is most effective and efficient in smaller sized and highly skilled teams. If teams can’t be quick to adopt a project, and make rapid progress, the agile method is not very effective.

Scrum, Kanban, XP are some of the methodologies used to develop the software form the Agile..

As the world keeps evolving day by day, technology has become an essential thing in our daily lives. Many tech-companies have been established due to huge expectation from people who are always enthusiastic about new inventions. However, not so many companies could survive in very competitive markets like PC computing, software, hardware, etc. In the early 1990s, as PC computing began to proliferate in the industry, software development faced a crisis. Expected estimated the time for a startup business to have a shippable application in production was about three years. This was even worse when it came to others area in the industry. For example, in aerospace and defense, the average time for a typical complex project could easily be more than 20 years. As a result, many projects ended up being cancelled in the middle of the development phase. Some were complete but did not meet all the business’s current needs. Conclusively, project management is the primary cause for those failures. Fortunately, the agile process management has been established from a small group of software leaders to solve the management issue. Agile is a set of development methods which promotes adaptive planning, early delivery. Not only that, it also encourages rapid and flexible responses to requirements changes at any phase of the development process. It is true to say that agile process has given companies, businesses a more sophisticated

Team members with diverse skillset and knowledge would be useful when developing software using agile. This whole team approach encourages effective and efficient team. It allows rapid project delivery. Project feedback is possible at early stages of software development lifecycle (Cockburn, Alistair, and Williams 2003). Therefore agile methodology is considered as cost as well as time effective.

This paper shows a survey of three spry methodologies including Extreme Programming, Agile Modeling, SCRUM, and depicts the contrasts in the middle of them and prescribes when to utilize them.

Despite the fact that agile process has many advantages, Software Organizations still using traditional process and not jumping into agile. We have summarized the characteristics, strengths, and weaknesses and issues of the conventional and agile methods in below Table1.
