1. What kind of data gathering would be appropriate to evaluate requirements? Why?
   
2. What method(s) would you use to analyze the data?
   
3. What kind of prototype would you use to evaluate your design during an early stage of development? Why?

Answer 1

ANSWERS :

ANS 1. Following kind of data gathering would be appropriate to evaluate requirements :

There are basically 2 types of data gathering :

1. Primary Data Gathering

2. Secondary Data Gathering

The most suitable data collection form here is :

- Qualitative Method involving Research : This is a method in which the data is gathered by using some mathematical calculations.It takes into account the mathematical feature rather than the emotions. It basically includes :

* Open Ended questions.

  

* Surveys over the internet.

* Interviews (more detailed)

- Quantitative Method : It again consists of mathematical calculations. It includes :

* Face to Face questionare

* Via Telephone and Email

  

  

ANS 2.  Following methods would be used to analyze the data :

They are of basically 2 types : Qualitative data analysis and Quantitative Data analysis.

In this case following method used :

1. Oualitative : It ususally consists of pictures, written texts etc.

* Data / Content Analysis

* Narrative Analysis

2. Quantitative : It is statistical way of data analysing .

* Using Mean

* Data Set / Hypothesis Analysing

ANS 3. Following kind of prototype would you use to evaluate your design during an early stage of development :

1. Feasibility Prototype :

It involves the creating of a prototype which is used to determine the feasibility of the design, to check the working and verify the possible threats that can lead to unsuccessful design of project.

  

2. Rapid Prototype :

It involves the creating of a prototype which is used to determine the results very fast i.e. in a short period of time, to get the results quickly this is used.
