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

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.

Suppose that a data warehouse for Big-University consists of the following four dimensions: student, course, semester, and instructor, and two measures count and avg_grade. When at the lowest conceptual level (e.g., for a given student, course, semester, and instructor combination), the avg_grade measure stores the actual course grade of the student. At higher conceptual levels, avg_grade stores the average grade for the given combination. a) Draw a snowflake schema diagram for the data warehouse. b) Starting with the base cuboid [student, course, semester, instructor], what specific OLAP operations (e.g., roll-up from semester to year) should one perform in order to list the average grade of CS courses for each BigUniversity student. c) If each dimension has five levels (including all), such as “student < major < status < university < all”, how many cuboids will this cube contain (including the base and apex cuboids)?

a) A Snowflake Shema is shown in figure below: b) The specific OLAP operations to be performed: 1. Roll-up on course from course_id to department. 2. Roll-up on a student from student_id to university. 3. Dice on course, student with department ="CS" and university = "biguniversity" 4. Drill-down on a student from the university to student_name. c) N = 4 dimensions The cube will contain 54 = 625 cuboids.

Suppose that a data warehouse consists of the four dimensions; date, spectator, location, and game, and the two measures, count and charge, where charge is the fee that a spectator pays when watching a game on a given date. Spectators may be students, adults, or seniors, with each category having its own charge rate. a) Draw a star schema diagram for the data b) Starting with the base cuboid [date; spectator; location; game], what specific OLAP operations should perform in order to list the total charge paid by student spectators at GM Place in 2004?

Discuss classification or taxonomy of virtualization at different levels.

Taxonomy of virtualization Virtualization is mainly used to emulate the execution environment, storage, and networks. The execution environment is classified into two: – Process-level – implemented on top of an existing operating system.  – System-level – implemented directly on hardware and does not or minimum requirement of the existing operating system. OR,  Virtualization covers a wide range of emulation techniques that are applied to different areas of computing. A classification of these techniques helps us better understand their characteristics and use  V irtualization is mainly used to emulate  ● Execution Environments: To provide support for the execution of the programs eg. OS, and Application.  ○ Process Level: Implemented on top of an existing OS that has full control of the hardware  ○ System Level: Implemented directly on Hardware and do not require support from existing OS.  ● Storage: Storage vi...
