We seek an Excel expert to transform our existing static rota workbook into a sophisticated decision-support calculator. This upgraded model will incorporate cost analysis, probability assessments, and scenario modeling, enhancing our ability to forecast staffing coverage dynamically. The project involves creating interconnected sheets and advanced formulas that will enable management to evaluate essential questions regarding staffing levels, role distributions, demand fluctuations, and associated costs. The primary objective is to develop a probability-based workforce calculator that effectively addresses staffing requirements, cost implications, and the impact of variable changes on operations.
