Weaknesses and Strengths (WO): In this quadrant Perrigo can minimize weaknesses by clutching its opportunities such as: minimizing W1 by taking the advantage of O1 and O4.      

Strengths and Threats (ST): Generate strategies here that utilize strengths to avoid threats as Perrigo is using S3, S6, and S7 to avoid T1 and other strategic options as well.

Weaknesses and Threats (WT): Generate strategies that minimize weaknesses and avoid threats; such as Perrigo diminishes W1 and avoid T1 and T3.
