One technique for handling risk is risk avoidance, which involves changing the project in some way so as to eliminate the risk altogether. An example of a risk that could be dealt with in this way would be a project team that is considering using a programming language and/or technology that the team is not familiar with. Moving forward with such a choice brings with it some potentially significant risks.
The project may take longer than anticipated due to the learning curve, or it may be discovered that features the team wants to implement are not well suited to the chosen technology. One way to handle this risk would be to select a technology that the team is already familiar with, as long as it can satisfy the needs of the project. This would allow the team to effectively avoid the risk.
Keep in mind that not all risks can be avoided, and avoiding a risk could lead to other risks. In addition, taking risks is sometimes necessary in order to take advantage of an opportunity. These should be some of your thoughts when considering whether or not to avoid a risk.
