TRUE OR FALSE
A constraint is a restriction that limits a design, such as cost, time, power, noise, safety, or available materials.
TRUE. A constraint limits design choices or project conditions.
WHAT IS YOUR TEACHERS FULL NAME?
R.M.L.
The ability to connect each requirement to its source, design response, test method, evidence, and final result.
A. CALIBRATION
B. SYSTEM BOUNDARY
C. TRACEABILITY
C. TRACEABILITY
WHAT IS ROOT CAUSE?
The deepest correctable reason a problem occurred; removing it should prevent or greatly reduce recurrence.
Criterion compared with constraint
A criterion is a measurable feature used to judge success. A constraint is a restriction that limits the design. Criteria help rank acceptable choices; a hard constraint can eliminate a choice.
If two variables are correlated, the correlation proves that one variable caused the other.
FALSE. Correlation shows variables change together; it does not by itself prove causation.
HOW MANY PETS DOES YOUR TEACHER HAVE?
3
A preliminary model or working version used to learn, test, or demonstrate selected features.
A. CALIBRATION
B. PROTOTYPE
C. SYSTEM BOUNDARY
B. PROTOTYPE
WHAT IS A CONTROLLED VARIABLE?
A factor intentionally kept constant so it does not unfairly influence the test result.
Symptom compared with root cause
A symptom is an observable effect that signals a problem. A root cause is the deepest correctable reason the problem occurred. Treating only the symptom may allow recurrence.
Verification asks whether the solution was built according to technical requirements, while validation asks whether it satisfies user needs.
TRUE. Verification asks “Did we build it correctly?” Validation asks “Did we build the right solution?”
FROM WHAT COLLEGE AND PROGRAM DID MR. MARTINEZ GRADUATE?
UNIVERSITY OF TEXAS AT EL PASO (UTEP)
COLLEGE OF BUSINESS ADMINISTRATION (COBA)FINANCE DEGREE WITH ERP CERTIFICATE
RESERVE OFFICER'S TRAINING CORPS (ROTC)The amount by which measured airflow falls below required or design airflow.
A. AIRFLOW DEFICIT
B. SYSTEM BOUNDARY
C. CALIBRATION
A. AIRFLOW DEFICIT
WHAT IS PRESSURE DROP?
The decrease in air pressure across a component because the component resists airflow.
Quantitative compared with qualitative data
Quantitative data are numerical evidence from counting or measurement. Qualitative data are descriptive, categorical, or observational evidence not expressed mainly as numbers.
Differential pressure means the pressures at two measured locations are exactly the same.
FALSE. Differential pressure is the difference between pressures at two locations.
WHAT IS MR. MARTINEZ FAVORITE SPORT?
AIRSOFT
The line that defines what is included, excluded, and what crosses into or out of a system.
A. SYSTEM BOUNDARY
B. RANGE
C. MEAN
A. SYSTEM BOUNDARY
WHAT IS THE SENSITIVITY ANALYSIS?
A check of whether the preferred decision changes when weights, assumptions, estimates, or inputs are varied.
Verification compared with validation
Verification determines whether the solution meets technical requirements. Validation determines whether the completed solution meets stakeholder needs and its intended purpose.
A hard constraint may be ignored when another design criterion receives a high weighted score.
FALSE. Every acceptable solution must meet a hard constraint; otherwise it is rejected.
HOW OLD IS MR. MARTINEZ?
27? Maybe
Comparing and adjusting an instrument against a trusted reference.
A. CALIBRATION
B. VERIFICATION
C. VALIDATION
A. CALIBRATION
WHAT IS PASS CONDITION?
The measurable result that shows a requirement has been met.
Supply air compared with return air
Supply air is conditioned air delivered into the occupied room. Return air is room air drawn back to HVAC equipment for re-circulation, filtration, exhaust, or further conditioning.
