The assessment of project success in Six Sigma predominantly focuses on metrics that directly relate to the core principles of the methodology, which aims to improve processes by identifying and eliminating defects. Option B highlights critical areas such as improvements in quality, efficiency, customer satisfaction, and cost reduction.

These metrics are essential because Six Sigma seeks to enhance the performance of processes and minimize variability. Quality improvement is measured through defect rates and process capability, while efficiency is assessed through time and resource utilization. Customer satisfaction is a key indicator of whether the improvements lead to a better experience from the user's perspective. Cost reduction directly ties to the financial benefits of improved efficiencies and quality.

The other options, while relevant in broader business contexts, do not specifically align with the objectives and methodologies of Six Sigma. Sales growth and profitability, while important, are typically outcomes of numerous factors, not strictly the focus of project evaluation in a Six Sigma context. Employee retention and job satisfaction are valuable metrics, yet they are more aligned with human resource management and organizational behavior rather than operational improvements aimed at reducing defects. Market share and brand recognition reflect external business performance and competitive positioning, which are also outside the scope of what Six Sigma specifically measures for project evaluation purposes.
