A system dynamics view of project management firefighting at a startup company
Fire fighting in project management is the unplanned allocation of resources to either fix problems or speed completion of a project. In a startup company environment, fire fighting oftentimes becomes the norm rather than the exception despite the best efforts to eliminate it. In particular, there …

Examining the effectiveness of online wildland firefighting education for structural firefighters
<p>Because many structural firefighters throughout the United States often respond to wildland fires in the Wildland/Urban Interface, the National Fire Academy developed an online educational curriculum to train structural firefighters in the basics of wildland fire fighting tactics. This training …
