uantifying the impact of one decision verse another is the primary challenge of the business manager. Total costs include both relevant costs and irrelevant costs and clarity of information concerning both is critical to success. Discuss two manufacturing companies of your choosing that could manage their business better focusing on relevant costs versus total costs. Also discuss two manufacturing companies that measure using total costs methods and do not need to break the data down differently. Explain with examples. If you were going to invest in one of the four companies, which would it be and why. Use quantitative facts in your decision and explanation. After your initial post, review other students discussion posts and discuss your agreement/disagreement with their findings and/or conclusions. Provide constructive feedback in your reply post(s). Offer a follow-up question in your post(s) to help keep the discussion going forward
