List three main types of risk. Explain Boehm's risk categories task breakdown structure . Briefly explain the categories of factors that need to be considered while risk identification.
Risk:
Risk is a problem that could cause some loss or threaten the progress of the project, but this has not happened yet.
These potential issues might harm the cost, schedule, or technical success of the project and the quality of our software device, or project team morale. A risk is an uncertain event or condition that, if occurs, has a negative on a project's objective.
The objective of risk management is to avoid or minimize the adverse effect of unforeseen events by avoiding the risk of drawing up contingency plans for dealing with them.
The above figure shows a task breakdown structure of Barry Boehm:-
- Risk identification consists of a listing of all the risks that can adversely affect the successful execution of the project.
- Risk estimation consists of assessing the likelihood and impact of each hazard.
- Risk evaluaton consss of rank9ing the rsik an d detemining risk aversion stragteigies.
- Risk planning consists of drawing up contingency plans and where appropriate adding these to the project's task structure with small projects, risk planning is likely to be the responsibility of the project manager but medium or larger projects will benefit from the appointment of a full-time risk manager.
- Risk control concerns the main function of the risk manager in minimizing and reacting to problems throughout the projects. This function will include aspects of quality controls.
- Risk monitoring must be an ongoing activity the importance and likelihood of particular risk can change as the project proceeds.
- Risk directing and risk staffing are concerned with the day-to-day management of risk. Riskadverion and problem-solving strategies frequently involve the use of additional staff.
The categories of factors that need to be considered while risk identification are given below:-
- Application factors
- staff factor
- project actor
- hardware or software factor
- Changeover factor
- Supplier factor
- Environment factor
- Health and safety factors
Any four of them are explained below:-
Hardware and software factor
A project that requires new hardware for development is likely to pose a higher risk than one where the software can be developed on existing hardware. When a system is developed on one type of hardware or software platform to be used n another there might be a high risk at installation.
Change over factor
The need for an all-in-one change over to the new system poses a particular risk. Incremental or gradual change over minimizes the risks involved but is not always practical. Parallel running can provide a safety net but might be impossible or too costly.
Supplier factor
The extent to which a project relies on an external organization that cannot be directly controlled often influences
the project's success For ex: Delays in the installation of telephone lines or delivery of equipment may be difficult to avoid_particularly if the project is of little consequences to the external suppliers
the project's success For ex: Delays in the installation of telephone lines or delivery of equipment may be difficult to avoid_particularly if the project is of little consequences to the external suppliers
Environmental factor
Changes in the environment can affect projects' success A significant change in taxation regulation could have serious consequences for the development of a payroll application.
