Yesterday we learned how to calculate the process capability level. The distance from the lower tolerance level and upper tolerance level is crucial. With the help of the process capability, we can have a deeper insight of the natural spread of the process. We can only improve the process if the tolerance level is shortened between the upper and lower tolerance level.
Our aim is to be on target with minimum variation. A state of statistical process control is not a natural state. We have to make sure about the persistent elimination of special causes.In terms of special causes, immediate action is required. With the help of statistical process control, we can gain knowledge and experience in a coherent manner. SPC needs to become a culture. It is important to understand the voice of the process, when the data indicates change, we need to recalculate control limits.
Change is a very difficult and challenging issue and often causes chaos in a company. Managers have vital roles in the implementation of change. They have to engage with the employees, explain why we need the change, how this change will effect the company and employees positively. Management of change is an emotional process where people can lose their expertise, skills, status, interests, security, territory, but most importantly relationships. Managers need to avoid the resistance of change by the employees and make them understand that in order to improve, we need to change. Although, in terms of resistence, employees could be less committed, conflicts could arise, their working behaviour can be changed and their motivation can be decreased. The management need to support all the employees in the process of change, they need to listen to them in order to deal with all their concerns, they have to share all the relevant information of the change, they need to gain their trust and involve them in the process.
