A dis-benefit is an outcome perceived as negative by one or more stakeholders.
Dis-benefits are actual consequences of an activity whereas, by definition, a risk has some uncertainty about whether it will materialize.
For example, a decision to merge two elements of an organization onto a new site may have benefits (e.g. better joint working), costs (e.g. expanding one of the two sites) and dis-benefits (e.g. drop in productivity during the merger).
These would all need to be considered and valued as part of the investment appraisal.
Note: With good transition planning there should be no dip in performance after the merger.
However, staff living close to the redundant site may find it more or an issue getting to the new site.
This is a likely outcome despite good transition planning.
