Changes are normal and welcomed in business, but not many companies know how to cope with them and turn them into opportunities. This is largely due to the fact that companies have never before witnessed so many changes and disruptions in business as they do today. This lack of experience is the key reason why companies fail to adapt to changes. Most notably changes are occurring from increased competition and rapidly changing environment that companies do not know how to respond to.
