A good way of introducing something new or implement a change is to take care of different elements, it deserves all attention. Of interest is that employees communicate with each other and joint the particular goal within a set timeline and budget. This is the idea behind project management. Through good structured project management you can make sure the goal is achieved.
Obviously there are larger and smaller projects. Important during projects is the allocation of resources (e.g. money, human resources) and realistic planning to achieve the target. Depending on the project you will also take into account internal and external communications.
