    • COMPILED & INTERPRETED
    • STEP 1 Naive implementation

    • STEP 2 What is failing?
    • STEP 3 Document the pre-requisites to fix that is failing
    • STEP 4 Document the graph
    • STEP 5 Revert your changes.
    • STEP 5.1 There are more pre-requisites in this level? YES - STEP 6 NO - STEP 7
    • STEP 6 Get the next pre-requisite GOTO STEP 1 repeat the process
    • STEP 7 Down one level GOTO STEP 5.1
    • STEP 8 Pre-requisite has been FIXED
    • STEP 9 Document the graph
    • APP A change STEP 1
    • APP A change STEP 2
    • STEP 3-4 APP Pre-req Pre-req A change Pre-req
