Case: Loop Mask is a company that manufactures mouth covers for adults and minors with a value proposition that has made them preferred over other brands. Their products are biodegradable and can be used for 40 hours each without altering their effectiveness.

They currently have a manufacturing plant located in the north of the country, but its capacity is no longer sufficient to meet demand. Projections for the next three years have been analyzed and show that demand will not only remain the same, but will increase by approximately 10%.

For this reason, the company is planning to expand its production plant to meet demand and add new products to its portfolio, such as gloves and sanitizing gels.

For this project a cost of $35,000.00 MXN per day and 150 days was established as the maximum estimated time for the completion of the project. The project manager can define the days for each of the proposed activities.
