Organizational Test Strategy

A long-lived, generic description of how testing is generally organized and performed across an entire organization, independent of any single project. It provides reusable rules, standards, and practices from which project-level test approaches are derived.

Related: Test Approach, Test Policy
Test Policy

A short, high-level statement of an organization's overall aims, principles, and intent regarding testing. It sits above the organizational test strategy and gives direction without prescribing detailed practices or techniques.

Related: Organizational Test Strategy
Test Approach

The concrete implementation of testing for one specific project or release. It selects starting point, techniques, levels, and exit criteria to fit that project's context, risks, and constraints, and is documented in the test plan.

Related: Organizational Test Strategy, Test Strategy Tailoring
Test Strategy Tailoring

Adapting the organizational test strategy to the specific context of a project, such as its risk profile, lifecycle model, technology, and regulatory constraints. Tailoring justifies deviations rather than applying organizational rules blindly.

Related: Test Approach, Organizational Test Strategy
Test Maturity Model

A framework describing staged levels of testing capability, from ad hoc practice to continuously optimized and measured processes. Organizations use it to benchmark current practice and plan improvement steps with defined entry criteria per level.

Related: Organizational Test Strategy, Test Process Improvement
Test Process Improvement

A structured, cyclic effort to raise the effectiveness and efficiency of testing, typically by assessing current practice, selecting prioritized improvements, implementing them, and measuring the outcome before repeating.

Related: Test Maturity Model, Root Cause Analysis
Test Team Roles

The defined responsibilities within a test organization, such as test manager, test leader, test analyst, and technical test analyst. Clear role definition prevents gaps and overlaps in accountability across the test process.

Related: Test Manager, Testing Competency
Test Manager

The role accountable for planning, monitoring, controlling, and reporting test activities, and for leading the test team and engaging stakeholders. The role focuses on management concerns rather than designing individual test cases.

Related: Test Team Roles, Test Plan
Testing Competency

A combination of knowledge, skills, and behavior needed to perform a testing task well, for example risk analysis, test design, communication, or tool use. Competencies are assessed and developed to match task demands.

Related: Skills Matrix, Test Team Roles
Skills Matrix

A grid mapping team members against required competencies, showing current proficiency and gaps. Test managers use it to plan training, assignments, and recruitment, and to identify single points of failure in the team.

Related: Testing Competency, Test Team Motivation
Test Team Motivation

The set of management actions that sustain team engagement and commitment, such as clear goals, recognition, autonomy, fair workload, and development opportunities. Motivation strongly influences defect detection and retention.

Related: Skills Matrix, Distributed Testing
Distributed Testing

Testing performed by team members or teams located in different places or time zones, or outsourced to another organization. It raises challenges in communication, handover, shared tooling, and consistent process adherence.

Related: Test Team Motivation, Test Stakeholder
Test-Driven Development

A development practice in which a failing automated test is written before production code, then code is written to pass it and refactored. Tests thereby drive design and provide a continuously growing regression safety net.

Related: Behavior-Driven Development, Regression Testing
Behavior-Driven Development

A collaborative practice where examples of desired behavior are written in structured natural language before implementation. These examples become executable acceptance tests and improve shared understanding among business, development, and testing.

Related: Acceptance Criteria, Test-Driven Development
Acceptance Criteria

The conditions a work item must satisfy to be accepted by its stakeholders. They define scope for testing and are typically expressed as concrete examples or checklist items agreed before development begins.

Related: Behavior-Driven Development, Definition of Done
Definition of Done

An agreed checklist stating what must be true for a work item to be considered complete, often including review, testing, and documentation. It prevents work from being counted as finished while quality activities remain outstanding.

Related: Acceptance Criteria, Entry Criteria
Retrospective

A regular team reflection at the end of an iteration or milestone examining what went well, what did not, and what to change. Test managers use it to adapt test processes and team practices based on evidence.

Related: Test Process Improvement, Root Cause Analysis
Shift Left

Moving testing and quality activities earlier in the lifecycle, for example reviewing requirements or writing tests before coding. Earlier defect detection usually lowers cost and shortens feedback loops.

Related: Static Testing, Test-Driven Development
Continuous Integration

A practice where developers merge code frequently into a shared mainline, with automated build and test runs on each change. It provides rapid feedback on integration defects and keeps the codebase releasable.

Related: Regression Testing, Test Automation
Test Plan

A document or record describing scope, objectives, approach, resources, schedule, risks, and exit criteria for test activities. It guides control and communication and is updated as context changes.

Related: Entry Criteria, Exit Criteria
Entry Criteria

Conditions that must be met before a test activity can reasonably begin, such as approved requirements, a stable build, or available test environment. Unmet criteria signal risk and justify a formal go or no-go decision.

Related: Exit Criteria, Definition of Done
Exit Criteria

Agreed conditions for declaring a test activity or level complete, such as coverage thresholds, defect closure rates, or residual risk acceptance. They support objective decisions about releasing or stopping testing.

Related: Entry Criteria, Test Plan
Test Estimation

Predicting the effort, duration, and resources needed for test activities using techniques such as expert judgment, analogy, or metrics-based models. Estimates are revisited as actual data accumulates.

Related: Test Plan, Test Progress Monitoring
Test Progress Monitoring

The ongoing collection of data about test execution, defect status, coverage, and effort against plan. It provides the factual basis for control decisions and for reporting to stakeholders.

Related: Test Control, Test Report
Test Control

Taking corrective action when monitoring shows deviation from plan, for example reprioritizing tests, reallocating people, adjusting scope, or changing exit criteria with stakeholder agreement. Control turns measurement into decisions.

Related: Test Progress Monitoring, Test Report
Test Report

A structured communication of test status and results to stakeholders, covering progress, coverage, defects, risks, and recommendations. Reports vary in depth from daily dashboards to formal test completion summaries.

Related: Test Progress Monitoring, Test Stakeholder
Test Metric

A quantitative measure used to track testing, such as defect density, test execution rate, or requirement coverage. Metrics must be interpreted in context and chosen to support decisions rather than to impress.

Related: Test Progress Monitoring, Defect Density
Earned Value Management

A project control technique comparing planned value, earned value, and actual cost to assess schedule and budget performance. Test managers can apply it to test effort and progress against the test plan.

Related: Test Estimation, Test Progress Monitoring
Test Stakeholder

Any person or group with an interest in test activities or their results, such as product owners, developers, operations, auditors, and customers. Their needs and influence shape communication and reporting.

Related: Test Report, Stakeholder Communication Plan
Stakeholder Communication Plan

An agreed description of who receives which test information, in what form, and how often. It prevents both information overload and dangerous silence by matching reporting to each stakeholder's decisions.

Related: Test Stakeholder, Test Report
Product Risk

The likelihood and impact of a product failing to meet stakeholder needs or causing harm. Product risks drive test prioritization, technique selection, and the depth of coverage applied to each area.

Related: Risk-Based Testing, Risk Analysis
Risk-Based Testing

Allocating test effort and rigor in proportion to analyzed product risks, so that high-risk areas receive early, deeper, and more varied testing. It aligns testing with what matters most to the business.

Related: Product Risk, Risk Analysis
Risk Analysis

Identifying risks and assessing their likelihood and impact, often using workshops or checklists. The resulting risk levels guide test planning, prioritization, and the choice of mitigation activities.

Related: Risk-Based Testing, Risk Mitigation
Risk Mitigation

Actions taken to reduce the likelihood or impact of a risk, such as additional testing, reviews, contingency planning, or scope reduction. Residual risk remains after mitigation and must be accepted explicitly.

Related: Risk Analysis, Residual Risk
Residual Risk

The risk that remains after mitigation activities have been applied. It must be communicated to decision makers, who formally accept it when approving a release or ending test activities.

Related: Risk Mitigation, Exit Criteria
Defect Management

The process of recording, classifying, prioritizing, tracking, and resolving defects, including agreed workflows and status models. Effective defect management preserves information for analysis and prevents duplicate or lost reports.

Related: Defect Triage, Root Cause Analysis
Defect Triage

A regular meeting where reported defects are reviewed to confirm validity, assign severity and priority, and decide on handling. Triage keeps the defect backlog meaningful and aligned with current risk.

Related: Defect Management, Severity and Priority
Severity and Priority

Two separate attributes of a defect: severity describes the impact on the product, while priority describes how urgently the business wants it fixed. They often differ and should be assigned independently.

Related: Defect Triage, Defect Management
Root Cause Analysis

A technique for tracing defects back to underlying process or technical causes rather than individual symptoms. Findings feed process improvement and prevent recurrence of similar defects.
