A single definition of agile methodology in software development is not easily found. We should consider agile methodology as an umbrella under which various agile methodologies rest. I will define agile methodology as an alternative to traditional ‘heavyweight’, linear project management methodologies that is marked by an adherence to and reliance on the individual not as a replaceable part, constant interactions between the project team and the customer, adaptiveness, customer collaboration, and…

Agile Methodologies for Software Development Introduction: In agile development model, the development of software is in incremental, rapid cycles. It is building new features on previous functionality with each small incremental release. The software quality is maintained by rigorously testing each release. It is useful for time critical applications. The most well-known current agile development life cycle model is Extreme Programming (XP). Why Agile model: The freedom that agile gives when…

Agile Software Development is a set of principles that have revolutionized the software development industry. They "seek alternatives to traditional project management" acting as "an alternative to waterfall, or traditional sequential development." (The Agile Movement, agilemethodology.org) It is thought that Agile came to be with the introduction of the Agile Manifesto, but their origination dates back much further. Dating as far back as 1970, sequential development has gained its critics. Dr…

Lean Software Development and Enhancing Software Development Projects Introduction Lean Software Development is essentially a transformation of lean manufacturing and IT principles and is a branch of agile development framework. The core concept here being eliminating waste. At the same time CMMI is a capability maturity model integration which is a process improvement technique that is used to bring about an improvement in a project, process or the entire organization for that matter. In…

[1]The Agile software development (ASD) methodologies have been established in various streams like academic, educational and also in professional software development. Understanding of how ASD methodologies are used, the kind of acceptance, successes and failures they have in the mentioned streams would be the main exploration. The findings from the web-based survey of Microsoft employees who involved in development, testing and management have indicated that around one-third of the people use ASD…

Agile Agile software development refers to a group of software development methodologies e.g. Dynamics System Development Model, Crystal Methods and Extreme programming (XP methodology). Agile methods attempt to minimise the risk in software in short time boxes called iterations. Every iteration includes all the tasks necessary to release the mini increment of new functionality: planning, requirements analysis, design coding, testing and documentation. At the end of every iteration the priorities…

Lean Summary Lean Software Development (LSD) is an implementation of Lean Principles in software development. In sum, every action that does not produce value is considered waste (muda)(Liker, 2005). The goal is to create a system (software development or otherwise) that is waste free. “Several Agile techniques can be used to achieve this in software development, making LSD and Agile similar at first glance (Austad, 2011)”. Origin/History It is important to note the history of Lean and the history…

Motivation Over the last several years, agile software development processes have become increasingly popular. According to Fowler (2003), the agile software engineering processes attempt to enable more flexible and adaptive software development than the traditional software engineering processes offer. Agile practitioners consider documentation as an important aspect for their projects but there is too little internal documentation available in their projects (Stettina and Heijstek, 2011). Although…

that was chosen for its development. Agile methodology is an emerging approach for software development while waterfall methodology is the traditional one. This paper presents the detailed and comparative study of agile and waterfall methodologies for project development. Both these methodologies have their applications in certain project development environments. The paper highlights basic principles, project development process, and planning and requirements value in agile and waterfall methodologies…

Lean on Agile In this competitive world of software development speed, accuracy and reliability play an important role during the development of a product. Traditional software development models like waterfall model lack these features which makes them not so feasible with the current scenario. The characteristics which traditional methods failed to address were achieved by agile methodologies, which are rapid, flexible, efficient and iterative. Lean, which was proven to be useful in the manufacturing…
