Countless books and articles have been written about leadership — on such topics as the differences between managing and leading, what makes a good leader, and how to become a better leader, among others. One frequent topic: Are leaders born or made? The Center for Creative Leadership (CCL) posed this question to C-level executives of companies in 53 countries ( www.ccl.org/leadership/pdf/research/areleadersbornormade.pdf ). Slightly more than half (53.4%) of the top executives think leaders are made, about a fifth (19.1%) think they are born, and a little more than a quarter (28.5%) think leaders are both born and made.

When the U.S. Food and Drug Administration (FDA), under the leadership of Ajaz Hussain, then the Associate Director of the FDA’s Center for Drug Evaluation and Research (CDER), launched the Process Analytical Technology (PAT) Initiative a decade ago, it set in motion a multifaceted search for a more scientifically based approach to pharmaceutical manufacturing and quality assurance. Hussain’s call for more PAT in the industry’s manufacturing operations was really more of a challenge to current practices than a proscriptive program. The pharmaceutical industry has responded with a renewed emphasis on understanding the scientific basis of its processes, and toward that end has made significant investments in personnel and tools.

Many plants shut down or reduce operations during a holiday period. Equipment may be in a non-standard condition while processes are on hold or shut down. Even though the plant is shut down, it is likely that hazardous materials are still present in storage tanks and process vessels. Equipment that is shut down may be opened for inspection or maintenance. Some plants continue to operate during a holiday but with reduced staff, delaying less-critical activities.
