|The TCM Methodology is a system by which the independent variables of the process are controlled using a PosiTrol Plan, rather than monitoring the product response variables after the fact. In TCM, most types of control charts are used. These are used to monitor the behavior of independent variables and response variables during production. The charts are synchronized in real-time to the corrective-action-system (CAL).
The corrective-action-system is equally synchronized to an out-of-control action plan (OCAP) that specifies to production operators how to bring the process back into statistical control. Another element of the Total Control Methodology is maintaining traceability of process changes as well as changes in consumables during production. The traceability element is the PosiTrol Log, and its function is again synchronized to the PosiTrol Plan, which brings about the total recapture of the process variables and other distinctive conditions during production.
To avoid the possibility of production personnel dominating the variability of the process, TCM also focuses on the human element in the production process. Work instructions, inspection instructions and visual (graphical) aids are integrated into a standard working procedure (Work Standard), which describes all the work that needs to be done by the operators. Another key element of TCM is the preventive maintenance of the production area and equipment. TCM ties a preventive maintenance plan with all the other elements to sustain "functional equilibrium" during the life of the production process.
Finally, the TCM book and course present a standard operating procedure for all the elements of TCM which can be tailored to your existing production facility.
