Question

1-Differentiate technology from methodology and from method. Can you come up with an example that differentiates these concepts in a specific context, perhaps software development?

2-Name activities in software development covered by various methodologies. Can you explain why more than one methodology is needed in developing a piece of software?

3-Why do we need to gather requirements?

4-When is the best time to gather requirements about a product?

Answer 1

3.The Process to gather the software requirements from client,analyze and document them is known as reqirement engineering.

The goal of reqirement engineering is to develop and maintain sophisticated and descriptive 'System Requirements Specification' document.

Requirements gathering is an essential part of any project and project management.Understanding fully what a project will deliver is criticalto its success.Requirements gathering sounds like common sense,but surprisingly,it's an area that is given far too little attention.

4.Good Requirements start with good sources.Finding those quality sources is an important task and fortunately one that takes few resources.Examples of sources of requirements include

->Customers

->Users

->Administrators and maintainance staff

->Partners

->Domain Experts

->Industry Analysis

->Information about competitors

->Get Detailed

It is good time to get requirements when that particular product needs development in its life cycle.

2.There are different activities in software development they are

Types of SDLC(Software Development Life Cycle)

* Waterfall model

* V-shaped model

* Iterative and Incremental model

* Agile Development

We need more than one methodology because all the properties and functions are not satisfied in one methodology so,we have to check all the methodologies.

1.Firstly we have to know that method is a tool to achieve aims/goals and technology is enabler to achieve aims/goals

Research Methods are the tools,techniques or processes that we use in our research.These might be,for example ,surveys,interviews,Photovoice,or participant observation.

Methodologyis the study of how research is done,how we find out about things,and how knowledge is gained.In other words,methodology is about the principles that guide our research practices.Methodology therefore explains why we're using certain methods or tools in our research.
