Culture is leader led.  When businesses are starting out, the culture is very often a direct reflection of how the founder likes to get things done.  As a business grows, the initial culture is diluted as more and more people join with their own habits and ways of working.  Because culture is made up of instinctive, repetitive habits and emotional responses it can't be copied or easily summed up. Each organisation's culture is unique.

One way to describe culture is the self sustaining patterns of behaviour in an organisation that determine how things get done.  At worst, culture can be a drag on productivity and become a negative contagion infecting every part of the business.  At best it's like the DNA of the business and can emotionally energise and create a positive contagion. What people feel, think and believe is reflected in the way they work, directly impacting the culture - and flowing into every other part of the business.

When positive culture forces and strategic priorities are in sync, companies can draw energy from the way people feel.  Accelerating a companies ability to gain competitive advantage or regain advantages that have been lost.
