Chain of command

The formal line of authority running from senior leadership down through each level of staff, showing who reports to whom and who may give direction within the laboratory.

Related: Span of control, Delegation
Span of control

The number of employees who report directly to one supervisor. Wide spans create flat, lean structures; narrow spans add management layers and cost.

Related: Chain of command
Delegation

Assigning a task together with the authority to complete it to a subordinate, while the manager keeps accountability for the outcome. Good delegation develops staff and frees leaders for higher-level work.

Related: Span of control, Competency assessment
Change management

A structured approach to moving an organization from its current state to a desired future state, including explaining the reason for change, engaging staff, and reinforcing new behaviors.

Related: Strategic plan, PDSA cycle
Operating budget

A plan for expected revenue and day-to-day expenses over one fiscal year, covering personnel, supplies, and other recurring costs required to run the laboratory.

Related: Capital budget, Budget variance
Capital budget

A multi-year plan for major purchases such as analyzers, buildings, and information systems, usually funded through reserves, depreciation, or financing rather than routine operating revenue.

Related: Operating budget, Return on investment
Budget variance

The difference between budgeted and actual revenue or expense, labeled favorable or unfavorable. Managers investigate large variances to find causes such as volume shifts, price increases, or staffing changes.

Related: Operating budget, Cost per reportable test
Cost per reportable test

Total laboratory costs divided by the number of tests reported to clinicians, used to compare efficiency across methods, platforms, or sites and to help set prices.

Related: Break-even analysis, Benchmarking
Break-even analysis

A calculation of the testing volume at which total revenue equals total cost, showing how many tests must be performed before a service begins to generate a profit.

Related: Cost per reportable test, Return on investment
Return on investment

A ratio comparing the financial gain produced by an investment with its cost, expressed as a percentage, used to rank competing equipment or project proposals.

Related: Capital budget, Break-even analysis
Lean

A process-improvement philosophy that removes waste such as waiting, overprocessing, and excess motion so work flows smoothly at the pace of customer demand.

Related: Process mapping, PDSA cycle
Turnaround time

The elapsed time from receipt of a specimen or order to reporting of the result, a core laboratory performance measure often tracked as collection-to-report or receipt-to-report intervals.

Related: Key performance indicator, Workload unit
Process mapping

A visual diagram of every step, decision, and handoff in a workflow, used to expose delays, duplication, and non-value-added steps before redesign begins.

Related: Lean, Root cause analysis
Workload unit

A standardized measure of laboratory work, such as a billable test or a weighted time unit, used to compare staffing needs, productivity, and cost across sections.

Related: Full-time equivalent, Cost per reportable test
Capacity planning

Estimating future test volumes and matching staff, equipment, and space to those volumes so service levels are met without carrying excess idle capacity.

Related: Workload unit, Strategic plan
Full-time equivalent

A staffing measure equal to one person working a standard full schedule. Part-time and overtime hours are converted to FTE so positions and budgets can be expressed uniformly.

Related: Workload unit, Turnover rate
Competency assessment

A documented, recurring evaluation of whether an employee can correctly perform assigned tasks, using direct observation, testing, and review of results at defined intervals.

Related: Performance appraisal, Proficiency testing
Performance appraisal

A periodic formal review of an employee's job performance against agreed goals and behavioral standards, usually linked to feedback, development plans, and pay decisions.

Related: Competency assessment, Succession planning
Turnover rate

The percentage of staff who leave an organization over a period, calculated by dividing separations by average headcount. High rates raise recruitment and training costs.

Related: Full-time equivalent, Performance appraisal
Succession planning

A deliberate process of identifying and developing employees who can fill key leadership or technical positions when current holders leave, retire, or are promoted.

Related: Performance appraisal, Strategic plan
PDSA cycle

A small-scale improvement method that repeats four steps, plan, do, study, and act, so a change can be tested, measured, and refined before wider adoption.

Related: Root cause analysis, Key performance indicator
Root cause analysis

A structured team investigation that traces an adverse event back to underlying system failures, rather than blaming individuals, and produces actions aimed at preventing recurrence.

Related: Failure mode and effects analysis, PDSA cycle
Failure mode and effects analysis

A proactive risk assessment in which a team lists each step of a process, scores how it could fail and how harmful that failure would be, then prioritizes fixes for the riskiest steps.

Related: Root cause analysis, Process mapping
Corrective and preventive action

The paired response to a detected problem: correcting the immediate issue, then changing the system so it cannot recur, with follow-up to confirm the fix worked.

Related: Root cause analysis, Proficiency testing
Key performance indicator

A quantifiable measure chosen to track progress toward a goal, such as specimen rejection rate or turnaround time, reviewed regularly by management.

Related: Balanced scorecard, Benchmarking, Turnaround time
Benchmarking

Comparing an organization's performance measures with those of peer institutions or recognized best practice in order to identify gaps and set improvement targets.

Related: Key performance indicator, Cost per reportable test
CLIA '88

The federal law that sets minimum quality and personnel standards for laboratories testing human specimens, classifies tests by complexity, and ties requirements to the certificate held.

Related: Waived testing, Proficiency testing
Proficiency testing

A program that sends unknown specimens to a laboratory and compares its results with peer laboratories, providing an external check on accuracy and required for regulated testing.

Related: Competency assessment, CLIA '88
Waived testing

Tests classified as simple and low risk under federal rules, for which the laboratory follows manufacturer instructions and basic requirements but is not held to full quality standards.

Related: CLIA '88
CAP accreditation

A voluntary peer-review program in which trained inspectors evaluate a laboratory against detailed checklists, granting accreditation for a set term and often serving as evidence of federal compliance.

Related: CLIA '88, Proficiency testing
Compliance program

An organized set of policies, training, monitoring, and reporting channels that helps a laboratory prevent and detect violations of billing, privacy, and safety laws.

Related: CLIA '88, Data governance
Laboratory information system

Software that manages orders, results, quality control, and reporting in the laboratory and connects instruments to patient records and billing systems.

Related: HL7 interface, Autoverification
HL7 interface

A standardized messaging connection that lets the laboratory system exchange orders and results with hospital or reference systems built by different vendors.

Related: Laboratory information system, Autoverification
Autoverification

Rules-based software release of results that pass predefined criteria, such as delta checks and reference ranges, without manual review, with exceptions held for technologist inspection.

Downtime procedure

A written plan telling staff how to order, test, and report results when the information system is unavailable, including backup documentation and reconciliation steps afterward.
