Changes are impossible to avoid and ignore, they happen every day and represent completely normal occurrences to people. Organisations encounter changes very often, and in order to survive and progress, they need to recognize the need for change in time. The important thing is how will organisations respond to the change and how it will affect their business. Some organisations are more entrepreneurial than others and look for threats and opportunities themselves and they are very successful. They are successful precisely because of their dynamism, adaptation, development and change. There are internal and external needs for change. Internal needs for change arise due to dysfunctions within the organization and can be more easily influenced by the organization, while external ones are often related to changes in the market, with laws, regulations, regulations or economic circumstances and are much more difficult to influence. Organizations can encounter numerous difficulties in such moments. Conflicts, lack of communication and resistance often occur. All difficulties can be avoided if the organization has a predefined plan. The organization needs to recognize when an insider is needed, and when an outsider is needed as the bearer of change, because this can greatly affect the success of implementing the change. Among other things, trust and ingenuity within the organization are an essential element in the entire change process, and it is easily possible that without them the changes won't be carried out with quality.
