Whether it’s something you are intentionally building or not - your company has a culture.  A bad company culture often results in less innovation, lower productivity and higher staff turnover. 
But creating a positive culture is more than just words on a wall or pizza on a Friday.  You can’t transform a culture overnight – however, developing a programme of continuous learning will help attract and retain talent as well as motivate and engage employees – all of which will go a long way in helping you achieving your culture goals faster.
