Linda Bryant recently started a small home-construction company. In an effort to foster high quality, rather than subcontracting individual work, she has formed teams of employees who are responsible for the entire job. She has contracted with a developer to build 20 homes of similar type and size. She has four teams of workers. The first homes were built in an average of 145 days. How long will it take to complete the contract if an 85 percent learning curve applies?
