Final answer:
The correct option is Businesses focus on their customers by swiftly addressing complaints, engaging in market research, offering quality products at competitive prices.
Step-by-step explanation:
Companies focus on their customers through various methods, ranging from fixing customer complaints quickly to implementing Total Quality Management (TCM) systems. By gathering information from customers and stakeholders, businesses can truly understand their needs and improve customer service accordingly. Conducting market research helps businesses understand the benchmarks of superior service.
Moreover, considering one's manager as an important internal customer can lead to professional development and job satisfaction by offering exceptional service internally. Specializing in a few quality products at competitive prices (core competency) often leads to more success than trying to offer a wide range. Additionally, a root cause analysis helps identify the true causes behind challenges, allowing for effective problem-solving and improvement.
