SharePoint can be implemented well or poorly depending on how an organization approaches it. The document discusses developing a strategy that includes planning, resources, culture, governance, and user experience. Key aspects that make SharePoint "good" include establishing roles and responsibilities, content standards, training, and designing the user experience around common navigation, branding, and information architecture. The summary emphasizes that whether SharePoint is viewed as "good" or "bad" depends more on how an organization implements it rather than the underlying technology alone.
