Answer
Forward engineering means the generation of code from diagrams

Answer
When analysis is complete and we start with design the following activities still need attention:

• Proof of concept programming
  
• Finding resources e.g. people, software etc.
  
• Planning
  
• Setting up the environment
  

Answer

We should always provoke early change in software than at later stage to minimize their fixing efforts and resources consumed at later iteration. Early change execution can be done by:

• Discover and change requirements during the design and implementation work.
  
• Embrace change is the key of iterative development to provoke change in early iteration.
  
• Early programming, tests, and demos help provoke the inevitable changes early on.
  
• Changing specifications will clarify the purpose of the design work of this iteration and also refine the requirements understanding for future iterations
  
• During early elaboration iterations, the requirements should stabilized, refined up to 80% as a result of feedback, early programming and testing.
