Question

A manifesto is normally associated with an emerging political movement-one that attacks the old guard and suggests revolutionary change (hopefully for the better). In some ways, that's exactly what agile development is all about. Although the underlying ideas that guide agile development have been with us for many years, it has been less than two decades since these ideas have crystallized into a "movement." In essence, agile methods were developed in an effort to over- come perceived and actual weaknesses in conventional software engineering. Agile development can provide important benefits, but it is not applicable to all projects, all products, all people, and all situations. It is also not antithetical to solid software engineering practice and can be applied as an overriding philosophy for all software work In the modern economy, it is often difficult or impossible to predict how a computer-based system (eg., a Web-based application) will evolve as time passes. Market conditions change rapidly, end-user needs evolve, and new competitive threats emerge without warning In many situations, you won't be able to define requirements fully before the project begins. You must be agile enough to respond to a fluid business environment. Fluidity implies change, and change is expensive. Particularly if it is uncontrolled or poorly managed. One of the most compelling characteristics of the agile approach is its ability to reduce the costs of change throughout the software process. Does this mean that a recognition of challenges posed by modern realities causes you to discard valuable software engineering principles, concepts, methods, and tools? Absolutely not! Like all engineering disciplines, software engineering contin- ues to evolve. It can be adapted easily to meet the challenges posed by a demand for agility In a thought-provoking book on agile software development, Alistair Cockburn ICoc02] argues that the prescriptive process models introduced in Chapter 2 have a major failing: they forget the frailtics of the pcople who build computer software. Software engineers are not robots. They exhibit great variation in working styles, significant dif- ferences in skill level, creativity, orderliness, consistency, and spontaneity Some com- municate well in written form, others do not. Cockburn argues that process models can "deal with people's common weaknesses with leither] discipline or tolerance" and that most prescriptive process models choose discipline. He states: "Because consis- tency in action is a human weakness, high discipline methodologies are fragile. If process models are to work, they must provide a realistic mechanism for en couraging the discipline that is necessary, or they must be characterized in a man- ner that shows "tolerance" for the people who do software engineering work. Invariably, tolerant practices are easier for software people to adopt and sustain, but (as Cockburn admits) they may be less productive. Like most things in life, trade-offs must be considered. 1 Agile methods are sometimes referred to as light methods or lean methods

Explanation / Answer

The manifesto described for Agile development has its own advantages.

The best practices for designing and developing software is mentioned in the following:

For Instance:

Consider a situation, where the client fails to address full requirements to the programmer/developer leading to improper software development and further resulting in mess.
Hence, the software development team may get into catastrophe due to the fourth value.

Agile development helps to overcome these issues:

1.Significance of self-managing workforce panel that has command over the task they execute.
2. Interaction and involvement of different stake holders.
3. A prominence on swift and speed delivery of software modules that persuades the clients.
