Implementation is the execution phase that ensures the objectives set during planning are achieved. All employees must understand their roles and responsibilities, and performance measures provide feedback to identify successes and areas for improvement. Companies closely monitor processes during implementation to quickly make necessary changes, such as expediting product delivery if shipping is identified as too slow based on common customer complaints. Functional plans lay out guidelines for each department, including production, marketing, finance, and human resources, to support the overall strategy. Functional policies provide boundaries to guide decision-making within each department.
