| Jan 25, 2012 at 4:40 | comment | added | Michelle | Hi again Paul :) Oh gosh, I don't envy you your project. Has your organisation fully implemented ISO-type project management processes, including risk registers, post-project debriefs, and variance reporting (cost and timeline)? I'm wondering if we can do some quality improvement without creating what will possibly be arbitrary statistical indices. :) | |

| Jan 19, 2012 at 17:36 | comment | added | rolando2 | Some questions to help us help you: 1. What is your indicator of quality of work? (What is the range of values it can take on? Does it follow a bell curve or can you otherwise characterize its shape?) 2. Will you have quality data on all 5 services and, for each of these, on both kinds of projects? If so, will you have comparable numbers of cases for each of these 10 combinations? 3. What would you consider a meaningful difference in quality? Knowledge of these questions will help determine the best statistical test and the necessary sample sizes per group. | |
