Question 3 (10 points)
Reflecting on the project that had just completed, Roger Rafa, the owner of a construction company
developing largely standardized affordable homes, wondered what went wrong. Nearly all of the 60
homes his company had just completed were behind schedule and significantly over budget. His
business was at risk.
When he met with the project team, the construction foreman blamed customers, sales
representatives and suppliers. Customers kept changing their minds about design details, and sales
representatives let customers make design changes well beyond established deadlines. Since
materials often required long lead times for delivery, construction crews waited as long as a month for
new construction materials. Customers did not pay for construction rework since they were told by the
salespeople that they would be able to make changes throughout most of the construction and Roger,
the company owner, believes strongly doing whatever it takes to delight customers.
What advice would you provide to Roger to improve the way his company manages these types
of construction projects? Please support the rationale for your advice.

Question 6 (10 points)
Ryan Riggles is a Project Management Professional (PMP) who applies project management
fundamentals with great skill from project selection to project close. Yet he finds it very frustrating that
many non-PMP project leaders in his company are outperforming him.
Ryan grew up in a family that honors harmony above all else. He works hard to instill this value of
harmony in his project teams. It seems to be working since team members have managed to
completely avoid conflict and they were quick to agree on work practices. Despite this, Ryan is not
seeing the positive results that other project leaders experience with their teams.
What advice would you provide to Ryan to improve the performance of his projects? Please
support the rationale for your advice.
