Hardwiring Happiness is a psychology/but actually mostly a self-help book. I obviously went into it with expectations that weren't met, but it's not all bad. I did get the psychological research that I wanted and more.
The Work Plan describes the primary objectives and provides for each review its internal identification code and the year in which we expect one or more reports to be issued as a result of the review. When reports are issued, they are posted to OIG's website.
The project plan includes the project scope, schedule, and cost baselines (and sometimes other baselines like quality). These baselines are collectively known as the performance measurement baseline. A baseline is what was originally planned for with any approved changes incorporated into it.
