Roark has just joined the company and in his role as lead analyst, he will be responsible for determining which systems development method the team uses to create the new application for a major medical supplier.
It is a new day at the firm. Roark has been in place for a few weeks, strengthening the communications skills of his employees, getting them to work much better together.
