1 What is the difference between tangible value and intangib

1. What is the difference between tangible value and intangible value? Give three examples of each.

2. Compare     and   contrast    between parallel development   and   iterative development methodologies in terms of their major elements, benefits and disadvantages?

3. Three types of questions can be used in an interview: Closed-ended questions, Open-ended questions, and Probing questions. When would each type of question be used?

4. What is the purpose of an approval committee in the software development process? Who is usually in this committee?

5. Review the www.seu.edu.sa Web site.   

a) Create a list of business functional requirements that the system meets with.

b) Create the different kinds of non-functional business requirements that the system meets with.

6. The management of Amazon.com Web site decided to extend its web-based system to include products other than books without a radical change in the applied business processes. Which of the analysis techniques will the analyst follow? How the factors influence the choice of the analysis technique?

Solution

1) Difference between tangible value and intangible value:

-------------------------------------------------------------------------------------------------------------------------------------------------------------------

2)

Parallel Development:

Here the development goes parallely ,we con go to further step with in completion of the further step

ex:when using parallel development we can do rquirement analysis for some part of the product and do the remaining thing at a time parallely here the development is some what faster

Advantages:
1) it reduces development time
2)due to that there will increase of reusability of components
3)it solves lot of issues in integartion

Disadvantages:
1)it requires developers with highly skilled
2)it depends on modelling skills

Iterative Development:

Here the development goes in a step by step process ,we can go to further phase with out completing the present phase

ex: we a software development life cycle here when using the iterative phase , fisrt requirment analyis,design then coding after that it implemented and the it will be tested here we cannot run all phases at a time

Advantages:
1)here we cannot design skeleton level design at beginning ,we can do only high level design
2)here we can track defects more effectively
3)less time for documentation
Disadvantages:
1)cost of design and architecture may rise
2)each phase will start in fresh there is no reusability

3)it cannot be applied on cheapr projects
