There are many types of relationships, some which originate and exist based on emotion, some which are based on the need to conduct affairs, with affairs not being of the heart.

For example a young organisation can be staffed with a mix of experienced and less experienced persons for certain periods of time to facilitate start up and growth.
With knowledge of the market and good strategic planning, one will determine what are the needs of the company for the interim or in economic terms, the short and long term. One will also determine what are the factors which are variable and fixed.
More importantly, one will identify the factors over which there is no control and one can only try to estimate the impact and prepare for it.
