 If I need to add some thing or need to go to the start I can do.
 While implementing he system using a Beta version I can get ideas or feedback from
the client.
 According to the scenario if I missed something I can fix it in the middle of the
project.
When I looking at the other methods I can’t do these works because some model developer
can’t go to the previous stages. And also other models we can’t check with a prototype or the
sample of the product. If the client has any changes in the system only after the final product
we can get the feedback.

System Analysis and Design
According to the Scenario
 Prototype model enables rapid delivery as it reduces the overall development time due
to reusability of the components and parallel development.
 Prototype works well only if high skilled engineers are available and the customer is
also committed to achieve the targeted prototype in the given time frame. If there is
commitment lacking on either side the model may fail.
 Changing requirements can be accommodated.
 Progress can be measured.
 Iteration time can be short with use of powerful prototype tools.
 Productivity with fewer people in short time.
 Reduced development time.
 Increases reusability of components
 Quick initial reviews occur
 Encourages customer feedback
 Integration from very beginning solves a lot of integration issues.

Task 1.1.2 (D 1.1)
Fact finding technics
There is four fact finding technics that are
 Examining documentation
 Interviewing
 Research
 Questionnaires
Examining Documentation
The documentation, form and Files the good analyst always will collect the fact form the
existing documentations rather than collecting form people the Documents that describe the
business function being designed true the documentation can collect the entire thing about the
company which is useful for our project this is the initial technics of fact gathering this will
more help full for understanding the system how I will be and more fats can gather in the
documentation following things we can get
 Company’s mission, objectives and strategic plan.
 Policy manuals, SOPs
 Samples of manual and computerized databases.
 Samples of manual and computerized screens and reports.
 Documentation of previous system studies and designs.
 Fact Finding Techniques
After gathering these thing, we can start doing our project work true their information’s like
there database how the manual database was worked and their mission and objectives the
developer can use the tools and techniques to draw the diagram true the gathered information

System Analysis and Design
Interviewing
The intervening is a method to collect information the interviewer which is the system
developer will ask the questions face to face for the customer to gather information in this
interview the interviewer should collect all the possible information about the client in order
