Notes for Seminar 1 - War

Chapter 7:

This chapter is about data gathering, where this chapter describes different methods on how to collect data for establishing requirements for our project. The book mentioned some important methods for collecting data, the methods whore interviews, questionnaires and observation. Every method have it’s pro and cons so you should choose a method that will help you to achieve your goal with that study. These methods above that the book mentioned have I personally some experience in during previous project I have used these kind of method. The book also mentioned a technique called Triangulation, which actually was the first time I heard about that technique. I think that the group could benefit from that triangulation because triangulation is a technique of data gathering meaning that data is drawn from different sources at different times but the book also mentioned that the validation through this technique could be a bit difficult to achieve.

Chapter 8:

When all the data have been collected by the different methods and techniques described in chapter 7, we will now analyze all the data. The data that can be received are two different types qualitative and quantitative data gathering. The difference between qualitative and quantitative data gathering is that qualitative data is more in depth question. When you ask question that request the person to reflect. During the analyze of the qualitative data we must search for recurring patterns. Quantitative data is data that can be translated to statistic data where we have short question that can later be summarized in average or percentage.

Chapter 10:

When the data is collected and analyzed then hopefully you know what the users need and one can establishing requirements a product will need to fulfil. We then have two different types of requirements that are functional- and non-functional requirements. Where functional is related to what the product should do and non-functional relates to what type of software the product should be able on. During the development of the product we should capture user characteristics, determine personas (typical user), predict scenarios and the use cases (user-system interaction). I personally think that during establishing requirements these things are very important factors that can help us enhance our product because otherwise there is chance that our final product doesn’t end up felling our main goal with this project.

Question:

Could we be able to use triangulation during the data gathering?
