Software Engineering Principles
Involve your prospective users in the process as early
and as often as possible.
4
Build an initial, simpler prototype and then add to it
incrementally
5
Code and test in small increments—never more than a
few blocks at a time.
6
Design the logic for your app before beginning to code
7
Divide and conquer.
8
Comment your source code or blocks so you can easily remember and
others can understand them.
9
Learn to trace blocks manually so that you understand
how they work.

Objects Over Time
