Routine decisions are decisions that people make hundreds of times each day without much thought based on established routines. These routine decisions are usually sufficient but sometimes fail, providing an opportunity to improve decision-making. Decisions in organizations can be strategic, tactical, or operational. Strategic decisions are made by top management and involve long-term goals and resource allocation, while individual decisions are influenced most by perception. Group decisions assess the organization's direction using tools like SWOT and aim for consensus without clear winners or losers.
