To conduct a CBA, you need to define your objective and criteria, list your options and alternatives, estimate the costs and benefits of each option, compare and rank your options, and choose the best option to implement. For example, your objective could be to increase productivity, with criteria such as time, money, quality, and satisfaction. Your options could be to work from home, in the office, or in a coworking space. Additionally, you can measure the costs and benefits of each option by considering expenses, risks, drawbacks, revenues, savings, and advantages. You can then use a table or chart to compare the costs and benefits of each option and assign scores or weights to each criterion. Finally, select the option with the highest net benefit or benefit-cost ratio for optimal execution.
