Lack of collaboration can be described as a failure to achieve an optimal outcome by working together. It is often caused by an unwillingness or inability for individuals and/or teams to come together and work effectively towards a common goal. This can result in inefficient communication, unnecessary delays, ineffective problem solving, and a lack of creativity. The impact of lack of collaboration can be severe, leading to decreased productivity, increased conflict and tension, and a lack of trust in the workplace. The best way to combat this issue is to ensure that everyone works together to share ideas, resources, and expertise – creating an environment of openness and respect.
