PRJ is getting ready to work on their extended1 Annual assessment of the effectiveness of their internal financial auditing controls based on Sarbanes-Oxley (SOX) Compliance. SOX was enacted in response to a series of high-profile financial scandals that occurred in the early 2000s at companies like Enron and WorldCom, among others, that upset investors’ confidence. It’s aimed at improving corporate governance and accountability, requiring all public companies to submit an annual assessment of the effectiveness of their internal financial auditing controls to the Securities and Exchange Commission (SEC). Based on the experiences of similar companies, PRJ decided to use the following approach in planning for this project. Explain (show with a precedence-relationships graph) what is the total duration and cost for the project?
