For this Assignment, you will create an annotated bibliography focusing on models used by companies to leverage diversification. These models also can serve to construct a portfolio management tool that characterizes business unit strategy and measures company results. These results are a valuable tool for evaluating how a corporate strategy differs from a business-unit-level strategy. 

To prepare for this Assignment, select four peer-reviewed scholarly articles, with each article addressing a topic of interest for research.

Submit an annotated bibliography for the four new (not used in previous discussions or assignments) peer-reviewed resources you selected. In your annotated bibliography, include the following:

• A full APA-style bibliographic reference including the author, title, publisher, and place of publication
• A summary of the document (2–3 paragraphs for each entry), including the main points, its purpose, the theoretical perspective on which it is based, and the scope
• For each article, evaluate the following:
  • Reliability (research methods used, theories used, and data on which it is based)
  • Appropriateness for the intended audience
  • Background and authority of the author
  • Limitations of the research (which can depend on the scope, reliability, age of the document, and bias)
  • Significance of the research
