The planning of future activities depends on the information obtained from different sources. This information serve as subsidy for taking actions, the next step of the PDCA cycle. Planning stage inputs: mission, vision, values, SWOT analysis, objectives, results, etc. Planning stage outputs: action plans. (D) Execute: this step consists in the implementation of the action plans established during the previous step (planning). Execution stage input: action plans. Execute stege outputs: actions implemented in accordance with the action plans. (C) Check: this step is the evaluation of the results obtained after implementation of the actions. Check stage inputs: the results od the actions implemented in accordance with the action plans. Check stage outputs: standardization of activities, preventive and/or corrective actions according to the results obtained. (A) Act: this step consists in the implementation of actions from the results obtained. Act step inputs: the results of actions executed according to the action plans.
