What is the difference between Harmony, Unity and Synergy?
Harmony is the result of suitable and appropriate parts being combined with one another to produce a pleasant effect.
Unity occurs when separate things or people are combined into one cohesive element with a single purpose.
Synergy is the working together of two or more separate things to produce a greater effect than the sum of their individual efforts.
