43 43  * **Personnel Increase**: Will result in a short-term drop in productivity, as the new team members require the attention of the original team members (explanations, answering questions, joint familiarization with the project, etc.), which distracts them from their actual work. After this period, productivity will rise above the original productivity as desired.
