One of the most common mistakes when it comes to strategy implementation is that responsibilities are not clearly defined. Employees are not sure what is expected of them or simply assume that someone else will do the job. Often with the result that goals are not achieved fully, not at all, or not within the desired time frame. Trouble and frustration are inevitable. Yet, this mistake can easily be avoided. Responsibility matrices, such as the RACI matrix, help organizations to clearly define, communicate, and document roles and responsibilities.
