This was a question I was asked on a recent project management course. I was able to introduce a simple model which went down well.
- assigning projects an overall priority – note: no low priorities due to a sustained level of demand for projects for a number of years
- scoring all projects when they are brought into the portfolio
- establishing portfolio level of governance
What I like about the article is that it is highly practical and is in use. Take a look at this article. It is one that needs further airing.
