Answer (D) is correct . The steps in a TOC analysis are (1) identify the constraint, (2) determine the most profitable product mix given the constraint, (3) maximize the flow through the constraint, (4) increase capacity at the constraint, and (5) redesign the manufacturing process for greater flexibility and speed.
Answer (A) is incorrect because Capacity at the constraint should not be increased until flow through the constraint has been maximized. Answer (B) is incorrect because The most profitable product mix should be determined before capacity at the constraint is increased. Answer (C) is incorrect because After identifying the constraint, the correct steps are determine the most profitable product mix given the constraint, maximize the flow through the constraint, increase capacity at the constraint, and redesign the manufacturing process.
