Which of the following is NOT one of the business improvement programs mentioned?

C is identified as the correct answer because the Waterfall model is not a business improvement program in the same context as the others listed. It is primarily a project management and software development approach that emphasizes a sequential design process.

In contrast, Kaizen, Lean, and Total Productive Maintenance (TPM) focus on continuous improvement within business processes.

Kaizen is a philosophy that seeks incremental improvement in productivity, efficiency, and quality. Lean aims to maximize value by minimizing waste in all forms. Total Productive Maintenance is a system that emphasizes proactive and preventive maintenance to maximize the operational efficiency of equipment. These methodologies are integral to enhancing overall business performance, whereas the Waterfall model is more about managing the progression of projects, particularly in software development.
