Risk Register
A risk register (PRINCE2) is a document used as a risk management tool and to fulfill regulatory compliance acting as a repository for all risks identified and includes additional information about each risk, e.g., nature of the risk, reference and owner, mitigation measures. It can be displayed as a scatterplot or as a table. ISO 73:2009 Risk management—Vocabulary defines a risk register to be a "record of information about identified risks". Example Risk register of the project "barbecue party" with somebody inexperienced handling the grill, both in table format (below) and as plot (right). Terminology A Risk Register can contain many different items. There are recommendations for Risk Register content made by the Project Management Institute Body of Knowledge (PMBOK) and PRINCE2. ISO 31000:2009 does not use the term risk register, however it does state that risks need to be documented. There are many different tools that can act as risk registers from comprehensive s ...

Probability
Probability is the branch of mathematics concerning numerical descriptions of how likely an Event (probability theory), event is to occur, or how likely it is that a proposition is true. The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates impossibility of the event and 1 indicates certainty."Kendall's Advanced Theory of Statistics, Volume 1: Distribution Theory", Alan Stuart and Keith Ord, 6th Ed, (2009), .William Feller, ''An Introduction to Probability Theory and Its Applications'', (Vol 1), 3rd Ed, (1968), Wiley, . The higher the probability of an event, the more likely it is that the event will occur. A simple example is the tossing of a fair (unbiased) coin. Since the coin is fair, the two outcomes ("heads" and "tails") are both equally probable; the probability of "heads" equals the probability of "tails"; and since no other outcomes are possible, the probability of either "heads" or "tails" is 1/2 (which could also be written ...

Failure Mode And Effects Analysis
Failure mode and effects analysis (FMEA; often written with "failure modes" in plural) is the process of reviewing as many components, assemblies, and subsystems as possible to identify potential failure modes in a system and their causes and effects. For each component, the failure modes and their resulting effects on the rest of the system are recorded in a specific FMEA worksheet. There are numerous variations of such worksheets. An FMEA can be a qualitative analysis, but may be put on a quantitative basis when mathematical failure rate models are combined with a statistical failure mode ratio database. It was one of the first highly structured, systematic techniques for failure analysis. It was developed by reliability engineers in the late 1950s to study problems that might arise from malfunctions of military systems. An FMEA is often the first step of a system reliability study. A few different types of FMEA analyses exist, such as: * Functional * Design * Process Sometime ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Issue Log
An issue log is a documentation element of software project management that contains a list of ongoing and closed issues of the project. While issue logs can be viewed as a way to track errors in the project, the role it plays often extends further. Issue logs can be used to order and organize the current issues by type and severity in order to prioritize issues associated with the current milestone or iteration. Issue logs may also contain customer requests and remarks about the various problems that can be found in current code. CAIR - Constraints, Assumptions/Actions, Issues, Risks - a log for tracking such items and managing them. Issue management An issue log is usually blank at the beginning of the project, but this is not always true for subsequent releases. In some projects, the issue log is actually used as a guideline for the release schedule; in that case the issue log can be populated with issues that are specifically tagged for completion in the upcoming release. As ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Risk Management Tools
Risk management tools allow the uncertainty to be addressed by identifying and generating metrics, parameterizing, prioritizing, and developing responses, and tracking risk. These activities may be difficult to track without tools and techniques, documentation and information systems. There are two distinct types of risk tools identified by their approach: market-level tools using the capital asset pricing model (CAP-M) and component-level tools with probabilistic risk assessment (PRA). Market-level tools use market forces to make risk decisions between securities. Component-level tools use the functions of probability and impact of individual risks to make decisions between resource allocations. ISO/IEC 31010 (Risk assessment techniques) has a detailed but non-exhaustive list of tools and techniques available for assessing risk. Market-level (CAP-M) CAP-M uses market or economic statistics and assumptions to determine the appropriate required rate of return of an asset, given ...

Risk Breakdown Structure
A Risk Breakdown Structure (RBS) within risk management is a hierarchically organised depiction of the identified project risks arranged by category. An Introduction to the Risk Breakdown Structure When planning a project to meet targets for cost, schedule, or quality, it is useful to identify likely risks to the success of the project. A risk is any possible situation that is not planned for, but that, if it occurs, is likely to divert the project from its planned result. For example, an established project team plans for the work to be done by its staff, but there is the risk that an employee may unexpectedly leave the team. In Project Management, the ''Risk Management Process'' has the objectives of identifying, assessing, and managing risks, both positive and negative. All too often, project managers focus only on negative risk, however, good things can happen in a project, "things" that were foreseen, but not expressly planned. The objective of Risk Management is to pred ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Event Chain Methodology
Event chain methodology is a network analysis technique that is focused on identifying and managing events and relationship between them (event chains) that affect project schedules. It is an uncertainty modeling schedule technique. Event chain methodology is an extension of quantitative project risk analysis with Monte Carlo simulations. It is the next advance beyond critical path method and critical chain project management. Event chain methodology tries to mitigate the effect of motivational and cognitive biases in estimating and scheduling. It improves accuracy of risk assessment and helps to generate more realistic risk adjusted project schedules. History Event chain methodology is an extension of traditional Monte Carlo simulation of project schedules where uncertainties in task duration and costs are defined by statistical distribution. For example, task duration can be defined by three point estimates: low, base, and high. The results of analysis is a risk adjusted proje ...

Risk
In simple terms, risk is the possibility of something bad happening. Risk involves uncertainty about the effects/implications of an activity with respect to something that humans value (such as health, well-being, wealth, property or the environment), often focusing on negative, undesirable consequences. Many different definitions have been proposed. The international standard definition of risk for common understanding in different applications is “effect of uncertainty on objectives”. The understanding of risk, the methods of assessment and management, the descriptions of risk and even the definitions of risk differ in different practice areas (business, economics, environment, finance, information technology, health, insurance, safety, security etc). This article provides links to more detailed articles on these areas. The international standard for risk management, ISO 31000, provides principles and generic guidelines on managing risks faced by organizations. Definitions ...

Illusion Of Control
The illusion of control is the tendency for people to overestimate their ability to control events. It was named by U.S. psychologist Ellen Langer and is thought to influence gambling behavior and belief in the paranormal. Along with illusory superiority and optimism bias, the illusion of control is one of the positive illusions. Definition The illusion of control is the tendency for people to overestimate their ability to control events, for example, when someone feels a sense of control over outcomes that they demonstrably do not influence. The illusion might arise because a person lacks direct introspective insight into whether they are in control of events. This has been called the introspection illusion. Instead, they may judge their degree of control by a process which is often unreliable. As a result, they see themselves as responsible for events to which there is little or no causal link. For example, in one study, college students were in a virtual reality setting to t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Likelihood
The likelihood function (often simply called the likelihood) represents the probability of random variable realizations conditional on particular values of the statistical parameters. Thus, when evaluated on a given sample, the likelihood function indicates which parameter values are more ''likely'' than others, in the sense that they would have made the observed data more probable. Consequently, the likelihood is often written as \mathcal(\theta\mid X) instead of P(X \mid \theta), to emphasize that it is to be understood as a function of the parameters \theta instead of the random variable X. In maximum likelihood estimation, the arg max of the likelihood function serves as a point estimate for \theta, while local curvature (approximated by the likelihood's Hessian matrix) indicates the estimate's precision. Meanwhile in Bayesian statistics, parameter estimates are derived from the converse of the likelihood, the so-called posterior probability, which is calculated via Bayes' r ...

Integer
An integer is the number zero (), a positive natural number (, , , etc.) or a negative integer with a minus sign (−1, −2, −3, etc.). The negative numbers are the additive inverses of the corresponding positive numbers. In the language of mathematics, the set of integers is often denoted by the boldface or blackboard bold \mathbb. The set of natural numbers \mathbb is a subset of \mathbb, which in turn is a subset of the set of all rational numbers \mathbb, itself a subset of the real numbers \mathbb. Like the natural numbers, \mathbb is countably infinite. An integer may be regarded as a real number that can be written without a fractional component. For example, 21, 4, 0, and −2048 are integers, while 9.75, , and are not. The integers form the smallest group and the smallest ring containing the natural numbers. In algebraic number theory, the integers are sometimes qualified as rational integers to distinguish them from the more general algebraic integers ...

PRINCE2
PRINCE2 (PRojects IN Controlled Environments) is a structured project management method and practitioner certification programme. PRINCE2 emphasises dividing projects into manageable and controllable stages. It is adopted in many countries worldwide, including the UK, Western European countries, and Australia. PRINCE2 training is available in many languages. PRINCE2 was developed as a UK government standard for information systems projects. In July 2013, ownership of the rights to PRINCE2 were transferred from HM Cabinet Office to AXELOS Ltd, a joint venture by the Cabinet Office and Capita, with 49% and 51% stakes respectively. History PRINCE was derived from an earlier method called PROMPT II (Project Resource Organisation Management Planning Techniques). In 1989 the Central Computer and Telecommunications Agency (CCTA) adopted a version of PROMPT II as a UK Government standard for information systems (IT) project management. They gave it the name 'PRINCE', which originally ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
