In the field (6) must indicate who is responsible for carrying out the control, measurement and monitoring of critical activity. Example: In charge; Director of Work; Surveyor; Quality technician; Laboratory technician; ... In the field (7) must indicate which is the log to use to compile the results of inspections and tests performed in the control, measurement and monitoring of critical activity. Example: Inspection and Testing Register; Control Sheet; Test Report; ... At each stage of control, measurement and monitoring, we need to identify their Risks, that is, events where outputs may not be what they want. Thus, the field (8) serves to identify risks associated with the control, measurement and monitoring, or which are the risks related to the type of inspection and testing set for each critical activity. Example: On receipt of materials when it inspects the Transportation Guide and Purchase Order, one of the associated risks can be "Purchase Order does not match the Transportation Guide. In field (9) a summary description of the identified Risk is to be made, which is intended to be the Explanation of Risk. Thus, the event associated with it will be featured and you can review the respective controls, measurement and monitoring, especially in cases where it is not possible to act on the causes. Example: On receipt of materials, the associated risk is "Purchase Order does not match" in its description we have "received materials do not match the purchase order." In the field (10) intended to briefly describe the effect as if the features previously identified risk to better identify the critical impact on its activity. This characterization will allow the reflection on the consequences of the effect, which will assess its severity using the defined criteria. Example: The effect of the risk "Purchase Order does not match," associated with "Material Reception" activity could be "May cause stop in production." Field (11) is used to assess the risk identified in (8), described in (9) and with the effects identified in (10). The assessment of risk will be conducted in accordance with the criteria described below. According to the definition given risk, we can base the assessment of the risk by two criteria: Probability (P) and Severity (S). Thus, for each risk or failure mode, we must estimate their Probability (P) and assign it a score. After analyzing the consequences of their effects, we will do the same for the Severity (S). Therefore, it is necessary to establish the criteria to be used in the estimation of Probability (P) and Severity (S) values. Proposals for these valuation criteria are presented below.
