DMAIC framework

The Control phase focuses on sustaining improvements, which is achieved through Statistical Process Control (SPC) charts to monitor performance and standard operating procedures to standardize the process. In contrast, tools like project chartering are used during the initial Define phase to establish the project's scope, not to sustain gains.

DMAIC is the standard, structured five-phase methodology used in Six Sigma to systematically improve existing processes. Option A correctly represents this sequence of phases, whereas Option B is incorrect because it mistakenly describes a manufacturing production cycle rather than an improvement framework.

• !Option A correctly represents this sequence of phases, whereas Option B is incorrect because it mistakenly describes a manufacturing production cycle rather than an improvement framework.
• !Option A is incorrect because the Improve phase focuses on implementing solutions rather than gathering initial customer requirements.
• !Distractors like Option D are incorrect because they invent non-standard phrases that confuse cycle time with quality metrics.
