Refactoring, TDD and Solutions Spikes are most known engineering practices that are fundamental for an Agile process.
Refactoring - "…is a disciplined technique for restructuring an existing body of code,
altering its internal structure without changing its external behavior." AND "Refactoring is a controlled technique for improving the
design of an existing code base." (Martin Fowler)
