Project evaluation wrap-up

Carlos Bana e Costa introduced the MACBETH approach to multi-criteria evaluation as a means to support decision making, some 20 years ago. In a nutshell, he showed that the analytic hierarchy process didn't work well and presented a solution: MACBETH.
In the past few articles, I've been covering the problems that can arise when evaluating (and that Carlos Bana e Costa fixed with his MACBETH) so you may want to start from there:


These articles are not about the MACBETH but about the problems it solves and how to work around them.

Interview with Peter Taylor

I'm doing some volunteer work for the Information Systems Community of Practice (IS CoP) of the Project Management Institute (PMI). This work consists on interviewing some remarkable Project Managers and share the resulting video on YouTube and the IS CoP website.
I'm very proud to share Episode 9 of the Who Is Program, featuring Peter Taylor, AKA The Lazy Project Manager. It's a 53 minutes long interview so if you have 1 hour on your hands, use it well!

Beware of scales

Linear scales and others
And so we continue exploring the problems that can arise when selecting and evaluating projects, in particular when we're real trying hard to be objective and transparent about the evaluation process. This time we'll be covering scales, that is, what is the impact that measurements (and their respective scales) have on the end result. Can it be that just changing scales can change the way we appreciate and perceive things?

4th Anniversary

4th Anniversary

Yes, it has been 4 years already. It was on May 23, 2010 when the first article "Change Management and Project Management" was posted here on Ah-Ha-Moments.
Since then many things have changed for the better with the objective of making this blog a good source of information for all Project Managers. Fulfilling this blog's mission has provided many challenges and many new friends, and I'd like to start by thanking those (friends) who took the time to share their views with comments.

Weights Do Influence, Big Time

Weights do influence, big time
I've been exploring the unexpected effects that can occur when evaluating/selecting projects and you can check the previous articles on this topic ("Dangerous mistakes when evaluating: election methods", and "Influencing results: just participate!") to start on the same page.. This article will continue on that direction and this time I'm going to show you how weights can influence the end result. That is, I'm going to provide an example where we evaluate 3 projects and get different best projects with small changes on the less important criteria (the criteria with the least weight) for the worst project evaluated. Funny thing, it that the weights attributed to each criteria will make a different project the winner!
You don't believe it, do you? Good, just keep on reading then!

Influencing results: just participate!

Just participate!
After checking how the election method we use can determine who wins an election (being that an election can be used to select which project to start next), it's now time to check how we can determine who wins by introducing or eliminating options.
That is, given:

  • a set of projects to select what the best option is, and
  • the criteria we're using to evaluate them

We can determine what the best project is just by introducing extra projects or removing options from the lot. And yes, you read this right. But you don't think it's possible, do you? Please keep on reading then!

Dangerous mistakes when evaluating: election methods


When evaluating something (selecting a supplier or which projects will get to start next month), bias are almost sure to occur.
But the worst kind of errors that can happen are those that we provoke when trying to make things more objective. We may believe we have a close to perfect process to select a supplier because it is based on an election process when in fact the result depends on what method we used to select the lucky winner.
