???? - ??????????????????????????? (Complete
uncertainty) - ??????????????????????????? (Relative
uncertainty) - ???????????????????????? (Complete certainty)
9- The alternative to proactive management is
reactive management, also called crisis
management. This requires significantly more
resources and takes longer for problems to
surface.

30Example of a Risk Check List
- Funding for the project has been secured
- Funding for the project is sufficient
- Funding for the project has been approved by
senior management - The project team has the requisite skills to
complete the project - The project has adequate manpower to complete the
project - The project charter and project plan have been
approved by senior - management or the project sponsor
- The projects goal is realistic and achievable
- The projects schedule is realistic and
achievable - The projects scope has been clearly defined
- Processes for scope changes have been clearly
defined

Monitoring project risks is analogous to a radar
scope where threat and opportunities may present
themselves at different times
