Describe the prototyping methods in software process.
Two methods
i. Evolutionary prototyping - In this approach of system development, the early prototype is prepared and it is then refined through various steps to final stage.
ii. Throw-away prototyping - Using this method a rough practical execution of the system is produced. The requirement difficulty can be identified from this execution. It is then leftover. System is then developed using some different engineering techniques.
Top down design: A top down design approach begins by identifying the main modules of the system, decomposing them into their lower level modules and iterating unless the desired

Define Brooks law. Software was delivered late, was not reliable, cost various times the original estimates and often exhibited poor performance characteristics.
State Lehman's First law. A program that is used in true world environment essentially must change or become progressively less useful in that environment.
