Scenario:
• A publishing company plans to replace its four proofreaders who look for errors in manuscripts with a new scanning machine and one proofreader in case the machine breaks down. Currently the proofreaders check 15 manuscripts every week between them. Each is paid $80,000 per year. Hiring new scanning machine will cost $5,000 each calendar month.
• How will this new system affect the proofreading department's productivity?
