PC Plan allows users that have permission to create SPC plans that include characteristic, data type, specifications, references to graphic data, instructions, standard causes, action, and other related data needed for a typical plan. The Plan module creates all necessary database table entries associated with the plan for the Template/Tk, DPC Entry and DPC Chart modules to act on the plan and its associated data. These rules are then used by Template/Tk and DPC Entry to enforce the data collection scheme. This rule enforcement, along with clear instructions that can be provided in text and graphics, supports ISO 9000 requirements.
