"During my career this situation has arisen for me quite often. If I notice that someone is completing their job in a way other than what is identified in their work instructions, I will approach the person and ask why they are doing the job in that way. The person may not have been trained adequately, or they may not be aware of the proper method. If this is the case, I will explain the proper method and reiterate the importance of following the steps as specified. If the person is purposefully not following the instructions, I will ask why they are doing the job in this way. Sometimes the team member has identified a better way to complete the task, in this case the instructions should be updated to reflect the new method so everyone else can be trained. If they are just taking short-cuts that could create problems, I will explain to them why this could cause a problem. After talking directly with the team member, I have found they will usually come around and follow the instructions."
