A project's score represents its benefit and can be entered into our Can Do project management tool. Now, a project can also "do harm". The question is, why should you do such a project in the first place?
For example, if the "profit" of a project is defined as a score, a project that does not make a profit but only a loss could have a negative score.
We have therefore changed the input field in the Can Do PM software to allow a negative score to be entered. Similarly, the graphics in the BubbleChart have been changed to allow a negative score to be displayed.
