Question

Iterative Process

a. What is meant by the iterative development process? Briefly explain its key attributes and benefits .

b. What is the Agile Manifesto and what are some of its key values? explain at least 2 values in terms of their implications on the agile model.

Answer 1

a. The iterative development is the process in which the software development of a large application is breakdown into small-small chunks. Its key attribute is that it works on following four phases :

1. Requirement Phase : Here all the requirements of the software are gathered and analyzed.

2. Design Phase : Here, based on the requirements, the design of the software is prepared. It can be either a new design or an extension of the older one.

3. Implementation and Test Phase : Here the implementation, coding and testing part of the software is done.

4. Review Phase : Here the software is reviewed and changes or additions are proposed.

Its key benefits are :
1. It generates a working software very early and quickly.

2. Because of small iteration, it becomes easier to test and debug the software.

3. It is easy to manage risks because risky pieces can be easily identified during various stages.

4. Here modifications can be done easily. Hence it is more flexible.

b. Agile Manifesto is simply a document that identifies or built on 4 key values and 12 principles for the development of agile software.

The key values of Agile Manifesto are :

1. Individuals and interactions among them over Processes and Tools - According to this, Agile Manifesto suggest that having best possible tools and processes to build a software is important but the thing which is more important is the group of right individuals and the interaction between the team as best possible tools in wrong hands is worthless.

2. Working software in place of comprehensive documentation - According to this, Agile Manifesto suggest that it is not required to make a very detailed documentation and wasting a lot of time before even writing a single line of code. Instead, agile model places shipping software to the customers as first priority and gathers feedback for development of future softwares.

3. Customer collaboration in place of contract negotiation - According to this, Agile model suggest that instead of contracts, focus should be on continuous development by taking periodic feedbacks and making your software better with time.

4. Responding and reflecting to changes over following a plan - According to this, Agile model suggest that with changing time, software teams must keep themselves up to date and they should have the ability to pivot and change direction whenever needed.
