The document discusses prototype modeling. It defines a prototype as a working model built to test design aspects or concepts. There are different types of prototyping models and processes. Benefits of prototyping include exposing misunderstandings, identifying missing functionality, and encouraging innovation. Potential disadvantages are insufficient analysis if the focus is only on the prototype, user confusion between prototypes and finished systems, and excessive development time.

3. WHAT IS PROTOYPE?
• Prototype is the process of quickly putting together a
working model (a prototype) in order to test various
aspects of a design,
• A Prototype is an early sample or model built to test a
concept or process or to act as a thing to be replicated or
learned from.
• . A prototype is a model or a program which is not based
on strict planning, but is an early approximation of the
final product or software system

4. •Hardware acquisition
•Software acquisition
•User preparation
•Personal: hiring and training
•Site preparation
•Data preparation
•Installation
•Testing
•Start up
•User acceptance

8. Need of prototype model
• A prototype is made. Completely built sample model is shown to user
and based on his feedback
.
• Prototypes are an essential part of the design process: realizing a design
in a physical form. This is beneficial in proving whether a new product is
viable, in terms of its mechanical, electronic and ergonomic design.
Having a working prototype demonstrates the benefits of your idea to
industry, in a convincing way, to help inspire confidence in the idea.

9. Benefits Of Prototyping
• Misunderstandings between software users and
developers are exposed
• Missing services may be detected and confusing services
may be identified
• A working system is available early in the process
• The prototype may serve as a basis for deriving a system
specification
• The system can support user training and system testing

11. Advantages of Prototype model
1.
Reduces development time.
2. Reduces development costs.
3. Requires user involvement.
4. Missing functionality can be identified easily
5. Encourages innovation and flexible designs
6. Results in higher user satisfaction

12. Disadvantage
• Insufficient analysis: The focus on a limited prototype can distract
developers from properly analyzing the complete project. This can
lead to overlooking better solutions, preparation of incomplete
specifications or the conversion of limited prototypes into poorly
engineered final projects that are hard to maintain.
• User confusion of prototype and finished system: Users can begin
to think that a prototype, intended to be thrown away, is actually a
final system that merely needs to be finished or polished. Users can
also become attached to features that were included in a prototype
for consideration and then removed from the specification for a
final system.

13. • Developer misunderstanding of user objectives:
• Expense of implementing prototyping:
• Excessive development time of the prototype
