EXIN Lean IT Foundation key terms
EXIN Lean IT Foundation · Get comfortable with the vocabulary.
- Value stream
The relevant end-to-end work and information path from demand to delivered outcome, including queues and necessary handoffs rather than only one team’s processing.
- Pull signal
A demand/capacity condition authorizing relevant upstream work under an explicit operating policy, not simply the presence of a visual board.
- Takt time
The available production or service time divided by relevant customer demand under stated units and boundaries, distinct from measured processing duration.
- Activity ratio
The explicitly defined active processing time divided by total lead time under consistent units and scope, without automatically classifying all other time as avoidable waste.
- Work in progress
The items within a defined started-but-not-finished boundary, whose effect on flow must be interpreted with throughput and lead-time conditions.
- Root-cause hypothesis
A proposed explanation for a process condition that requires supporting evidence, distinct from a diagram label or a fixed number of why questions.
- Countermeasure
A proposed intervention addressing a supported cause, requiring an appropriate bounded test and outcome verification rather than adoption because it appears on a diagram.
- Control plan
An agreed arrangement defining ongoing measures, ownership, response conditions and review needed to sustain and verify a process improvement in daily operation.
- Specification limit
A boundary expressing the actual customer or other requirement, distinct from a statistical control limit describing observed process behavior.
- Operational definition
A clear statement of what is counted or measured, the relevant unit and population, and how collection is performed so results are interpretable.
- Defect opportunity
A defined relevant chance for nonconformance per unit, whose count and consistency affect the interpretation of defects-per-million-opportunities calculations.
- Rolled throughput yield
A model of the proportion passing an entire specified sequence without rework, calculated from appropriately conditioned step yields rather than their simple average.
- Common-cause variation
Variation arising from the current process system under the stated stability model, distinguished from an identified unusual influence without treating all fluctuations as special causes.
- Risk Assessment
- Related: Risk Management, Security Audit
The process of identifying, analyzing, and evaluating risks to determine their potential impact and likelihood, often used to prioritize security controls.
- Risk Management
- Related: Risk Assessment, Business Continuity Plan
The coordinated activities to direct and control an organization regarding risk, including risk assessment, treatment, acceptance, and communication.
- Security Audit
- Related: Risk Assessment, Compliance
A systematic examination of an organization's security controls, policies, and procedures to verify compliance with standards and identify areas for improvement.
- Risk
- Related: Inherent risk, Residual risk, Risk assessment
The effect of uncertainty on objectives, usually described by the likelihood of an event and its potential impact.
- Inherent risk
- Related: Residual risk, Control, Risk assessment
The level of risk that exists before any controls or risk responses are applied to a process, asset, or activity.
- Residual risk
- Related: Inherent risk, Control testing, Risk acceptance
The risk remaining after controls and risk responses have been implemented and their effectiveness has been considered.
- Risk analysis
- Related: Risk assessment, Likelihood, Impact
The part of risk assessment that examines the nature, causes, likelihood, and impact of identified risks. It may use qualitative or quantitative methods.
- Risk evaluation
- Related: Risk assessment, Risk appetite, Risk tolerance
The part of risk assessment that compares analysis results with risk criteria to decide whether risk is acceptable.
- Risk register
- Related: Risk owner, Risk response, Risk reporting
A structured record of identified risks, including owners, ratings, controls, responses, and status, used to monitor and manage risk.
- Threat
- Related: Vulnerability, Likelihood, Impact
A potential cause of an unwanted incident that could harm an asset or organization, such as an attacker, malware, or natural event.
- Vulnerability
- Related: Threat, Vulnerability management, Control
A weakness in a process, system, or control that could be exploited by a threat to cause harm.
- Likelihood
- Related: Impact, Risk analysis, Threat
The probability that a threat event will occur and exploit a vulnerability, expressed qualitatively or quantitatively. It is one factor used to rate risk.
- Impact
- Related: Likelihood, Business impact analysis, Risk analysis
The consequence or magnitude of loss or harm to the organization if a risk event occurs. It may be financial, operational, legal, or reputational.
- Control
- Related: Control testing, Inherent risk, Residual risk
A safeguard, policy, procedure, or technical measure that reduces the likelihood or impact of a risk event.
