Software Engineering

1.) What is a risk?
*
Risk is a concept that denotes the precise probability of specific eventualities. Technically, the notion of risk is independent from the notion of value and, as such, eventualities may have both beneficial and adverse consequences.
*
Risk can be defined as “the threat or probability that an action or event will adversely or beneficially affect an organisation's ability to achieve its objectives”[1].

In
engineering, the definition risk often simply is:
 \text{Risk} = (\text{probability of an accident}) \times  (\text{losses per accident}).\,

Or in more general terms:

 \text{Risk} = (\text{probability of event occurring}) \times  (\text{impact of event occuring}).\,

2.) Identify at least 5 software risk. Discuss each.

*Risk analysis- is a technique to identify and assess factors that may jeopardize the success of a project or achieving a goal. This technique also helps to define preventive measures to reduce the probability of these factors from occurring and identify countermeasures to successfully deal with these constraints when they develop to avert possible negative effects on the competitiveness of the company.
*Risk management- is the identification, assessment, and prioritization of risks followed by coordinated and economical application of resources to minimize, monitor, and control the probability and/or impact of unfortunate events.[1] Risks can come from uncertainty in financial markets, project failures, legal liabilities, credit risk, accidents, natural causes and disasters as well as deliberate attacks from an adversary.
*Commercial Software Risk-is an inherent part of software development. It is therefore an important factor in software investment decisions.
*Project itself- "What obstacles do project managers face to successful completion of an Information Technology project?”
3.)Risk management strategies?
*it is the strategies to manage risk include transferring the risk to another party, avoiding the risk, reducing the negative effect of the risk, and accepting some or all of the consequences of a particular risk. Certain aspects of many of the risk management standards have come under criticism for having no measurable improvement on risk even though the confidence in estimates and decisions increase.
