Harriet has 3 projects, with the following conditions: Project 1 _ CPI=.8 & SPI =.9 and is in Closing phase of project Project 2- CPI=1.1 & SPI=.8 and is in Execution phase of project Project 3 _ CPI= 1.0 & SPI=1.0 and is in Planning phase of project Which of her projects shows the most potential for success, of being on schedule and on cost, solely based on CPI/SPI at this moment in time?
Project 2
None of these
Project 1
Project 3
Let's first look at the definition of Schedule Performance Index and Cost Performance Index; A value >1 shows ahead of planned schedule and under planned cost, a value<1.0 is behind planned schedule and over budgeted cost, and a value=1.0 is on planned schedule and on planned cost. Project 1 is incorrect as CPI and SPI are both over planned cost and behind schedule. Project 2 is incorrect; while CPI is under planned cost but SPI is behind schedule. Project 3 is correct as both parameters are on schedule and cost at this time. None of these is incorrect as Project 3 does meet critieria. (PMBOK 2013 Rev 5th Edition, pgs 217-225).
