The marketing mix model has four key elements- product, place, price and promotion, which constitutes the four Ps. The four Ps need to work together. The only way a marketing plan can succeed if the four Ps are aligned and are worked in unison. Their role is to implement the strategic direction the top management has chosen.  However if one of the four Ps is not in sync with the others, then the entire plan becomes compromised.  All four Ps must be integrated and directed in the same direction; otherwise a company’s competitive model wouldn’t succeed. The four Ps shouldn’t be applied in a static way either. There will be times when one changes. The four Ps can be readjusted and need to be readjusted when one of its Ps’ changes.
