prototyping

prototyping

1. what is the purpose of prototyping

   • prototype is a small part of a system that may not be functional
   • prototype is created to demonstrate an element of a system
   • the people will be able to see what the system is going to be
   • they will be able to change the bad and keep the good things about the system
   • they can get fees back for the clients and the customer will be happier with the end products

2. what are the advantages

   • you can see what the product is goingto be like before the real system
   • you will save money when using prototypes before creating the real thing, before you've tested the system and youll know every thing works
   • you can just throw aways any prototyps what aren't worth to keep and change the design, this will save you money to create the real system

3. what are the disadvantages

   • the prototype will take a long time to create and it may not be right and need to change it all
   • Incomplete application may cause application not to be used as the full system was designed Incomplete or inadequate problem analysis.
   • if the prototype doesn't meet the objectives then you have just wasted all that time and money on that one prototype

4. the different feature and formats of prototyping

   • functional. it performs actions and functions that final system will perform
   • illustrate. this is usually an interface such as an input or output screen, this will show what the system is going to look like.
   • evolutionary. this is built on during the features or design and development process. this is refined till the it becomes the final application
   • throw-away. this shows the client the features and design of the system. this will not be used again. this can be created in different software
