Question

_____ is a systems development technique that tests system concepts and provides an opportunity to examine input, output, and user interfaces before final decisions are made.

a. Modeling
b. Prototyping
c. Scrum
d. RAD

Answer 1

Option b("Prototyping") is the correct answer for the above question.

Step-by-step explanation:

• Prototyping is a type of Model which follows the phases of SDLC and used to develop the software project.
• In this model only a copy of the software is developed and seen by the customer that the developer is developing the right thing or there may be any changes.
• The above question asked about the Model which is used to provide a copy of the software. That model is known as the Prototyping Model which is described above. Hence Oprion b (Prototyping) is the correct answer for the above while the other is not because:-

1. Option 'a' states about Modeling which is not a model of SDLC.
2. Option c states about Scrum, which does not provide the prototype to the customer.
3. Option d states about RAD which is not the correct answer.
